If you didn't read this, it's your fucking fault if anything goes wrong.
If you already have the game (you're just updating/upgrading), empty your patch folder first.
Anyways, use the installer, THEN merge the included patch folder (if there isn't one, it's because there weren't any necessary at the time this package was made).
Also merge the included Graphics folder if applicable.
Patches can be obtained at: http://ux.getuploader.com/MaiDenSnow_Eve_1/
Always check for newer patches, and always grab all available ones, just in case.
The game knows if a patch is out of date, so there's nothing to worry about.

If you want to play in Japanese, then take the language_eng.rvdata2 file that's in the game folder and rename it to _language_eng.rvdata2.
I've tested this one meself, the game should be stable.
About as stable as D&P's current state at least.
Have fun, faggots.

++++++++++IF YOU ARE STUCK ON A SCREEN THAT HAS A RABBIT RUNNING ON A CLOCK THEN READ THIS++++++++++
When starting a new game for the first time, if it seems to be stuck, you have to press up, left, up, down, right. In that order. It was Rabbit's way of making sure his players read his Readme basically. I checked to make sure this was still the code this time (Tricksy Rabbit changed the fucking thing once before. Sorry.).

++++++++++HOW DO I MAKE THE TURNS WHEN GETTING RAPED NOT GO SO FAST?!?!?!?1one!!?+++++++++++++++++++
In the config (use the included config translation) if you highlight one of the Wait options (it's the japanese option below the volume sliders) and press A, S, or D, you'll make a slider for that option appear that lets you adjust it. Then just do that.


~~~~~Bonus WAT DO Section (You don't need to read this but it's a bunch of useful info.)~~~~~
~About Difficulty Selection~
You have three difficulties:
Beginner (All appearance options unlocked, can retry from floor you died.)
Normal (Appearance options must be earned. Retry sends you to start of dungeon you died in.)
DAIMAKYO (Hard mode. You revert to Level 1 at start of each dungeon and on death. You get more gold.)
Difficulty is locked in for that file once you've made your choice, aside from restarts.

NOTE: From here onwards, when I mention being able to "use a scroll" it means there is a specific scroll-type consumable with the intended function, not a generic "Scroll" item that works for various things.

~Weapon Tips~
Best melee weapons IMO are lances, rapiers and estocs, mainly due to Stinger (has 2 tile range).
This refers to Rapier, Nightfox, Vanguard Lancer, Fox Tooth, and Falcon Stake basically.
The Jade Blades are baller as fuck poison daggers that have great use.
Athame Knife is basically an anti-undead weapon. Is a good sidearm for the kung-fu skeleton butler faggots.
For guns, most are good. The long-range rifle is great for those fucking magic wielding goats (you can outrange them). The handcannon revolver thing is fantastic due to knockback chance.
The Knuckledusters allow to you punch any enemies in point-blank range while also shooting them.
Bullets cap at 80 per slot regardless of type.
Except for the two Silver-Pointed Bullets you start with, all bullet boxes autocombine if applicable.
So if you have a box of 20 Silvers and a box of 30 (and they're not currently loaded), they will be combined into a box of 50.

In general, it's good idea to pack different weapons for different monsters. A good general use weapon that has Stinger, and then stuff that specifically does bonus damage to different types of monsters (check by selecting a weapon and pressing Shift). Some examples are Claymores (anti-beasts), Sky-Shooters (anti-air), Serpent's Fang (anti-dragon/snake), or Silver Bullets (anti-undead). When a weapon has anti-something on it, you can see the bonus it does (it'll say something like anti-whatever+numbers) so be sure to compare that against your general use weapon to see if it'll outdamage it.


~About Gear: Durability~
All weapons, armor, accessories, and innerwear have durability. Only hats have infinite durability.
At zero durability, it breaks, and you can't equip it anymore.
Appropriate clothing damage will appear on your standing cut-in if what you're wearing showed up on it.
Accessories that are broken will not appear damaged, you just won't be wearing them.
You can increase max durability with scrolls. You can restore lost durability with scrolls.
A different (more rarer) type of repair scroll is required to fix anything that's broken.
All damaged gear can be repaired at a safe-area. There are 3 ways to do so.
1. A bonfire. Every safe-area has one. Look for a torch, fireplace, or brazier, and interact with it.
	NOTE: Bonfires may sometimes be disabled on higher difficulties.
2. The salescat NPC. Found in most (but not all) safe-areas.
3. The dwarf NPC. Found only in a few safe-areas. Only he can fix broken or cursed shit.
Upon fixing armor or clothing, it's possible the gear will be altered to make use of the materials left.
A skirt may get shorter, a bra covers less, that kind of thing. This slightly changes the gear's stats.
The dwarf NPC can be used to restore a piece of gear's appearance, or lock-in it's current appearance if you like it as is and don't want it to be changed.
These services aren't provided for free however, so keep that in mind.


~About Gear: Upgrades, Enchantment, Slots, Curses, and Identification~
If a piece of gear's durability is ??/?? it means it has not been identified yet.
You can use scrolls to ID them. The same 3 repairing methods also have ID options. Bonfires sometimes do not.
Equipping unidentified gear will immediately identify it.
Gear can be [Base stat related Enchantment][Name][Combat related Enchantment][}#].
Base stat related enchantments affect your base stats, and aren't related to the gear's actual stats.
Combat related enchantments are things like an innate element or status effect the gear may inflict.
If it's +#, it has better stats than usual. If it's -#, it's cursed.
Cursed gear has worse stats than usual, and cannot be unequipped.
You can use a scroll to uncurse gear. The dwarf can also uncurse it.
If playing on Beginner, you can uncurse gear at a bonfire.
You can use a scroll to upgrade gear. The dwarf NPC can also upgrade gear.* He can also fuse gear to make different gear. You can preview this service at a bonfire, but it cannot be done at one.
Enchanting gear is different. It requires that a gear has slots, which are small square icons that appear on the gear's icon. The enchantments themselves are consumable items similar to scrolls. The number of slots on an enchantment show how many slots a piece of gear will need. You can enchant an enchantment with another enchantment. This lets you stack enchantments, but will increase the slots required. If you try to enchant something what's slots are already full, it will override the whatever is in the slots. The game will warn you about this instead of just doing it and possibly fucking you. You can increase the slots of something via fusing gear, but note that this could change the item itself to another item. Should this happen, you may need to fuse it with something else to try to get it back to the item it was. The game lets you preview what fusing will grant you so you know before you potentially make a mistake.

*Gear gains EXP as you use them in battle, or when you use a scroll/psalm on them. The Dwarf cannot upgrade a piece of gear if it doesn't have enough EXP. There is unfortunately no way to check this, as far as I'm aware. The upgrade menu works like a shop. You move down to the item, and press Right for however many upgrades you want, do so for each item you plan to upgrade, then hold Z. Just like if you're buying something.


~Explanation of the Running state~
The icon that is a square with a <<< in it is this status.
It's use is to denote that Eve is mobile. It's applied whenever you're moving.
It's removed once you take an action that ends with you facing an enemy or wall.
It is required to use some skills. Jumping for example. Or Stinger.
Pretty much anything that requires a running start.


~General Tips and Controls~
Press Z to attack. Press X to pull up the Subscreen.
On the Subscreen you can view Inventory, gear, the System Menu, and so on.
There's five pages of stuff to view.
Pressing D will always pull up the System Menu.
You can change stances by holding the X key.
When wielding a gun, switch from the Intimidate stance to the Avoid stance when enemies are close.
When wielding a blade, use the Riposte stance most of the time.
If the blade you're using is Fox Tooth or Nightfox, use the Avoid stance instead.
This is because its Ice spell triggers off of Stinger.
Use the Exspell stance when approaching a mage.
If you're being raped, the Indure (should be Endure but w/evs, Rabbit's foreign.) stance sucks. Switch it to Refuse if want to actually get the fuck up.
If you have it, the Accept stance makes enemies (and you if futa) cum faster. Has its uses.
Not important, just neat: In Accept stance, Eve spreads her legs a bit. If on all-fours, she sticks her ass up in the air more.

You can Backflip (you attack and jump back a tile) by holding Q and pressing Z.
To check for traps, double tap W. Range decreases with repeated use.
Q and W are what the game refers to as the L and R buttons, if your display setting is set to keyboard.
You can pull up a mini-map with Shift. Holding Shift while moving gives you the instantish movement.
Hold Q to pivot (good to aim without moving). Hold W to only move diagonally.
Holding Q is also for Looking. The log will mention stuff Eve can see within line of sight.
This lets you identify revealed traps so you know what kind they are. They have to be adjacent to Eve though.
Looking is also how you figure out where an adjacent Invisible enemy is.
It also tells you if there's an enemy in the distance.

There are two different skill menus, accessed by A and S respectively.
After bringing up your menu of choice, you simply press in the direction of the skill.
Then select the skill with Z to use it.

----------------------------------------------------
All skills except Rondato, Cross/Lance of Fire, and Splash of Holy Vial require MP.
* means the skill also requires a Holy Vial.
^ means the skill requires SP (Green gauge. Builds as you deal/take damage.).
You can see the range of a skill by highlighting it and then holding Q.

Cross of Fire and Lance of Fire are used to achieve your Super Form (Limit Break. EX Mode. Wield a Noble Phantasm. Bankai. Accession. Turn it up to 11. Accel Turn. Gear 2nd. Kaioken. Whatever, I'm running out of examples here.) basically. Gun (Cross) and Sword (Lance) respectively.
You don an armored form, sprout laser wings, and all your stats that help your equipped weapon shoot up.
The armored form has a time limit, but the wings stay until you move to the next floor.
The armored form represents the defensive stat increases, the wings, offensive.
The armored form also looks different based on your outerwear. Wings are the same regardless though.

Quick-Swap lets you change gear without getting attacked. Do NOT move after using the skill, just open the menu and make your switch.
Splash of Holy Vial and Redemption both can Purify enemies besides their stated effects.
Maiden-Snow only works on enemies that have been Purified. It's also your ultimate attack.
Protector's Oath happens immediately and doesn't actually eat your turn. Very useful skill.
The difference between the two versions of Redemption is the AoE. That's it.
Holy Vial x# is just a count of how many of 'em you have in your inventory is all. Caps at 5.
Purifier's Craft takes a shitload of MP, usually around 2/3rds. It's worth it to make the Holy Vials though.
Rondato requires you to have the Running state.
Rondato is used to Jump. Angelic Hallow can also be used to Jump.
You can Jump diagonally.
The -none- square denotes a space you can slot a skill or item into. This is done from your regular menus.
The rest of the skills do what they say they do.
Helpful Tip: If using guns, a fantastic combo is Redemption followed by Under-Legs.

Please note, recently Rabbit has added skills for the two-handed rifles that I do not have listed here.
Unfortunately they are new, so I'm unfamiliar with them at the moment, sorry.
Perhaps a newer version of this miniguide thing I will have them added then.

~About Traps~
FUCKING CHECK FOR THEM. THEY CAN FUCK YOU OVER HARD IF YOU ARE NOT CAREFUL.
There is only one beneficial trap, the Guidance Trap.
Its appearance is that of an old timey lamp post or something. Use Looking to check the trap first.
The point is, the Guidance Trap lets you return to the safe area you came from if you want to, and then also gives you the Guidance status effect.
This effect makes you less susceptible to traps for the current floor, and also makes you go down THREE floors instead of just one when you pick a Door. Doors will autoupdate to reflect this, so a safe-area that may have been farther away might just be right there waiting for you.
You can also get the status effect from using a Bestseller scroll (the scroll that lets you see the whole map of the floor you're on).

~How to Change Appearance~
If playing on Beginner, all the appearance options are unlocked by default and can be changed in your room.
Just go to the Mirror. The trade-off being you can only change appearance here.
On Normal and up, appearance options have to be earned and bought. The Mirror is now in the Chapel.
You spend Exorcism points on them at the Mirror. You unlock them to be bought by completing challenges. Challenges will be listed on their entry on the Mirror (they're greyed out until you complete the challenge).
You gain Exorcism points by killing enemies. Enemies give bigger bonuses if they've been purified, more if they've been purified and then killed, and the most if they've been purified and then killed by the Maiden Snow skill.
Appearance options include stuff like bust size (smaller and bigger), hair styles, hair colour, skin colour, tanlines, glasses, ear types, and always having the appearance (regardless of actually having the status) of futa, pregnancy, lycanthropy, or rabbithropy (with tails and ears of the latter two being both toggleable).
After being bought at the Mirror, appearance options can be changed at any time from the Appearance menu option.


~About Virginity, Piety-Vow, Morale and H-Skills~
While your virginity remains intact, you will have the Piety-Vow passive self-buff.
This is a general stat buff, that also makes holy skills and silver weapons more effective.
As soon as an enemy J-J-JAMS IT IN though, you lose the buff, technically making you weaker.
Oral and anal is fair game of course.
This ties in to your Morale stat, a stat of Eve's general happiness and sanity.
Further trauma (rape, humilation, getting her shit pushed in, etc.) lowers Morale.
Being a good little Sister (purging the unclean, stamping out heresy, etc.) raises Morale.
As your Morale goes down, you become more susceptible to a Total Break. This is an instakill in the form of a mindbreak (or the body just gives out if you're a NIKU-VENI) in reaction to x H-action happening to Eve. By instakill, I simply mean that regardless of HP, it instantly zeroes. It isn't a Game Over in the form of instant VIT-0. Unwilling orgasm is usually the fastest route to this.
As you continue to do lewd actions (or have them be done to you, willing or no) you will slowly raise passive H-skills (shown as percentages) that trigger addiction to those acts. Addiction to these acts makes it easier for them to happen during gameplay. Corruption states like addictions and such can be removed by Confession at the Church. It costs Morale though.
Now I imagine you might be upset by the whole having sex makes you weaker thing. Here's the trade-off:
Inscriptions, and being able to progress a sidequest (Both mentioned below.). Also, nothing in the game absolutely requires you to be a virgin.


~About Inscriptions~
Upon being impregnated by monsters, there's a chance that their cursed semen places an inscription on the walls of your uterus. Yeah. Anyways, Inscriptions are passive debuffs/buffs that take effect starting from when you birth the child of whatever had said semen. They stack, and can be quite awesome. They're a relatively new feature, so I haven't gotten it completely down yet, but you can end up stronger with Inscriptions than you were with the Piety-Vow. It's just hard to do, as you have to manage your vitality well. Once you have one, you can keep it in your Uterus (note that you can only keep on in there at a time), or transfer it to a piece of gear. In order to do that, you need a rare item found in the final dungeon (Divine Ink it should be called IIRC). Besides Inscriptions for your Uterus, you can also get them for your gear. They are also incredibly rare drops from monsters, and typically require you be deep in a dungeon. They are easier to get on harder difficulties of course, though still rare.


~About A.C. and "Indurance" (FFS, Rabbit.)~
The former is defense. The latter is resistance to H-skills.
More risque clothing has lower Indurance because it's easier to get at your naughty bits.
The rest of the stats are pretty self-explanatory.


~About Vitality~
This final stat is in the upper right corner at all times. It is what saves you from getting fucked into a coma. It slowly lowers in field-areas (not in safe-areas) as you explore and do things.
You raise it with food. How good your HP/MP regen is is directly proportional to how high it is.
At VIT-0, you run the risk of an aforementioned coma-fuck if you HP drops to zero.
Should it happen, you "die" via coma-fuck. This is where a roguelike form of permadeath comes in.

You get two options:
1. Retry - Start at beginning of field-area with nothing (no items, or weapons) but whatever Eve is still wearing. Usually bra/underwear, stockings, and hat. If playing on Beginner (you casul), you can choose to start on the same floor you got dropped on. Note that unless you're good or are lucky, you're probably still boned (and will thusly get boned). Especially if it's a later field-area. If you're playing on DAIMAKYO difficulty, your level is also reset to 1.

2. Refreshed Start - Accept your loss, and start the game completely over. Should you choose this option, you can choose what happens to your Sexual Values. You can keep them (Eve remains as traumatized as she was at the time of the many dickings, and remains not a virgin.), clear them (also resets virginity), or export them for later viewing (also clears them IIRC).

NOTE: If playing on Beginner and you've made it to the Church, doing a refreshed start (whether via Game Over, or via the Passenger's Tax bad end) will allow you to go straight to the Church from Eve's house if you want. You'll also be allowed to open the chest containing the Sister's Essence in the house (see further down for more on that essence).


~About Memories~
As you progress through the game and upon interacting with certain cloud looking tiles may give you a message about unsealing or acquiring a memory. Basically you get an item with a blue or red crystal for an icon. Memories are this game's (may contain CGs) events. Instead of forcing cutscenes on you, you are simply given the Memory, and then can choose to watch it at your leisure. Blue crystals are regular events while red crystals are H-events. The Good and Bad Ends are done via Memories as well. You access these from the System Menu. Another item that can appear in this menu are key memories. These change options like whether or not Eve knows what happened to the city, or allow you to reset your progress against the 5 Lords. Other keys don't do anything on their own, they just provide options in certain blue/red crystal memories. I would recommend against messing with any of the key-memories that actually change stuff. Might accidentally fuck with events in the future. The key-memories that affect crystal memories are fine though, since you can't select them anyways.


~Mini-Walkthrough~
The Story:
You are Eve Roland, an Inquisitor for the Church. You are also the Snow Maiden, an experienced hunter of the supernatural. You have been called to the capital and given a task; to investigate the strange tidings coming from a city in the mountains. You are told to go to the Chapel/Church in the area and speak to its Priest, who will debrief you on the status of what's happened to the city.
On your way there, you are set upon by some beasts but you easily dispatch them. As you look upon your destination from a cliff outlook, a mysterious stranger greets you. After some terse conversation, he suddenly stabs you and (in the struggle) you fall off the cliff!
You wake up hours later in the snow at the bottom of the cliff (your wounds having healed), in an area called Windbreak.
And this is where the story begins.


Exploration:
In each field-area are Doors. These Doors hint at (or tell you if on Beginner) which safe-area it eventually leads to, along with how far away said area is. To get to said area, you keep picking the same door (the distance to target gets smaller) until there's no distance mentioned (meaning this door is the last door, enter to enter the safe-area). That's all there is to it. Switching doors midway through will change up your distance, possibly setting you back. Bosses don't start appearing until at least the 7th level/floor of an area. If you're after a boss, just alternate doors if it hasn't shown up on the way to your destination.

The 5 Lords:
-Wild Hunt- A tall claymore wielding hunter, who summons other hunters and bowmen. Found in Snow Forest.
-Cheve Bellia? (I can never remember its name)- A floating horse head. Summons frogs. Found in Underground Stream/Spring Channelway.
-Belle- A wolf girl. Summons a werewolf familiar. Can infect you with lycanthropy, rabbithropy (be wearing a Bunny-Suit and contract lycanthropy, and it will change into rabbithropy instead), or turn you into a futa. Found in City High Road/Main Street. The werewolf familiar can also infect you with lycanthropy or rabbithropy if he gets his cum into you (any orifice will do).
-Dullahan- A skeleton knight riding a horse. I don't think he summons but am not sure. Found in Sleeping Cemetary.
-Minotaur- A fucking minotaur. Does not summon. STRONK AS FUCK instead. Found in The Catacombs.

I am using map names where applicable. 
Any second listed area names are what the translation in game calls it.

Gameplay Route to Bad End (aka My Little Inquisitor Can't Be This Shit):
Using the map provided, take the bottom route (as in, hit the City Outpost along the way) to the Church.
Talk to Priest at the Chapel to get your mission (represented as the Restless Night memory).
Now to fail it spectacularly.
You have to go and get raped by the 5 Lords. Good luck.
After that, go back to the Church for your bad end.
Once you're in your room, you can choose to restart on the same difficulty or higher.

Gameplay Route to Good End (aka Destroy All Heresy):
Using the map provided, take the upper route, the more roundabout way to the Church. (Good luck!)
Talk to Priest at Church to get your mission (still represented as the Restless Night memory), and also be told of what happened to the City.
City Outpost is now safe to go to at this point.
Now to complete the mission.
You have to go and kill the 5 Lords. Good luck.
After that, go back to the Church for good end, and more shit to do.
You can now go back to your room, where you can NG+ if you want. The Sister Essence is also found here.
The final dungeon also is open. It is accessible from Windbreak.

There are two ultimate weapons in this game, one melee, one ranged. You can only get one per playthrough.
It depends on which location between the Hollow Tree and the Inner Sanctum you go to first.
Go to the Hollow Tree first to get the Nameless Blade, a usable katana.
Go to the Inner Sanctum first to get the Piece of Artifact, a non-usable item.
You use the item you chose for Alchemy at the Dwarf to forge the ultimate weapon you chose.
You will require any non dual-wield bladed weapon (Longsword, Claymore, Sawtooth, whatever) and the Nameless Blade to forge the ultimate sword (Brace yourself), the Epicidium Edge. Yeah. What a name.
You will require any dual-wield gun weapon (Limb-Fires, Knuckledusters, Automators, whatever) and the Piece of Artifact to forge the ultimate guns, the X-Fire P#s (I don't remember what number.).
The ultimate armor (the Cardinal Robe) is made from crafting. Sister Essence + Sister's Robe. Make sure the robe you use has lots of slots if possible.

The map doesn't mention that the cat and dwarf NPCs move around sometimes. Dwarf can also be found at the outpost or the watermill, if found at his place prior.
After getting your mission, if you're still a virgin, the priest will give you a chastity belt.
The Witch Doctor can also give you the chastity belt, if you're not a virgin when you meet him (or it's if you get him to abort your pregnancy, not sure which).
The chastity belt is called Leather Bondage. It protects against being raped, with the tradeoff being you can be more easily bound by tentacles or vines.
After getting your mission (or it's after you've been to Hollow Tree/Inner Sanctum), revisit places that had clothing chests for a second chest with new (and different) clothes. Map doesn't mention this either. I'd apologize, but I didn't make the map.
I still don't know if the DISREGARD THIS part of the map refers to anything yet.

Witch Doctor Sidequest:
If you've been to the Watermill, you may find that NPC there.
He cures you of pregnancy, futa, lycanthropy, and rabbithropy.
He also gives you a sidequest to impregnate Belle to get Animal Essence.
This means be futa, and let Belle ride your dick.
You can be turned futa by Belle, or by the plant girl miniboss Dame Verte.
Cumming inside usually is enough, just watch for a message in the log saying your fluid druid went away patting their stomach happily.
This sidequest is also dangerous as fuck for obvious VIT-0% reasons. So good fucking luck.
So what's the Animal Essence for? Crafting.
Animal Essence + Gothic Bustier = Stray Cat costume.
Gives you the benefits of lycanthropy (ie. Being a cat girl.) without the detriments. Also very nice clothing that shares the Gothic Bustier's armored form (a bitchin' scarf).

Animal's Passion Church Memory:
To get this memory, you need to have the Animal's Passion status and be in the Church.
You also need to not be a virgin.
This easiest way to accomplish this is to go be a slut until your morale gets to -200.
The Accept stance will help with that, but you'll need to manage your VIT carefully.
Anyways, at -200, you should get a masturbation skill.
So go the church, and masturbate until you trigger the status effect. That should be about it.

The Final Dungeon:
If you've seen the ending memories, you'll have seen the hint for this.
Trek all the way back to Windbreak. It will now be a bit larger of an area.
In this new room, there's a sukumizu in the bottom right corner (Jump.).
There are also chests for storage and such.
There's two different difficulty trees. The left one lets you up the difficulty for the save file.
It's a permanent change that also applies to any NG+s.
The right tree lets you toggle Extreme Mode. This mode makes it so that dungeons do not reset when you leave.
So say you finish a dungeon on floor 7, you go back and you'll start there. Enemies are also stronger.
This mode is independant of your actual difficulty level. This mode also makes rarer drops a bit easier to get.
Anyways, the objective of the final dungeon is to find a ritual sacrifice and rescue her. Once you do (she takes up an inventory slot) you have to find your way out, and return her to either the Priest or the Witch Doctor. The reward is another inventory slot for your storage chest. You can do this until your chest has (IIRC) 100 slots. As to the dungeon itself, the doors don't lead to other areas, they instead give you a hint as to what the next floor will entail. This dungeon is very chaotic in nature, and each floor location could have a different theme or be filled with traps, or have tentacle beds everywhere, or have a lusty atmosphere or anything. There is a rest area that can be found within the dungeon in the form of a hut that the Witch Doctor can be found in. There are also new enemies that are only found in this dungeon. This dungeon will most likely fuck your shit up right out the gate, so make sure to manually save before you go in there. When you get to a floor with a sacrifice on it, Eve will hear their moans and comment on it. Another tip to remember is that if you come across a Chaos Vortex, there will (almost always) be a sacrifice somewhere else on the same floor, as they are usually paired up. Finding a sacrifice will disable the Vortex it's paired with. It's also the easier way to destroy one. Vortexes are monster spawners. And they can be incredibly nasty to deal with.

Rescue Sacrifices Sidequest:
This is a new sidequest that was added recently to the game. It is unlocked for your participation as soon as you get your mission (Restless Night) from the Priest in the Church. In all field-areas there is now a new Door you can get to called "Lightless Path". This door does not take you towards anywhere, it only takes you deeper into the field-area, increasing your distance away from all other areas. However, you must take this door to eventually reach sacrifices (similar to how they're handled in the final dungeon). Each field-area has one sacrifice you can find. Same rules apply as with sacrifices in the final dungeon, only without having to worry about a Chaos Vortex. You instead have to make it out alive after retrieving it. I find that the best thing to do is to try and immediately find the Guidance trap and use it to get back to the safe area you came from. Then go to whichever is closer between the Church and the Watermill to deliver the sacrifice safely. The rewards are the same as the final dungeon sacrifices, upgrading the size of your storage chest.

Elder Essence Miniquest:
After you get the sukumizu, you also unlock the opportunity to this miniquest. The Elder Essence can be found in the final dungeon, specifically in the safe-area that can appear there. The Door to said safe-area only appears on floors with a multiple of 3 (floors 3, 6, 9, and so on). The description for it MAY mention an abandoned house or fortress, but unfortunately that's not a guarantee. Anyways, you use the Elder Essence for Alchemy at the Dwarf.
Elder Essence + Sukumizu = Old-Type Sukumizu (Has a different name, but that's what it looks like.)
This is basically the ultimate underarmor (only the Diabolical Bondage has better stats, but you have to deal with all its penalties).
It's also one of the few underarmors that makes you take zero penalties for being dripping wet or moving through water in Spring Channelway.



I think that's about all the tips and general need to knows I can think of.
Good luck, Snow Maidens.
