Forgotten Mansion

Warning: This dungeon is HARD

A lot of the enemies can give you status effects (poison, bleeding, fear, ???, captured, fallen)
Some of the enemies are very tough, particularly the ones found deep in the dungeon after you've played the right song on the piano. Frost resistance is recommended.
The dungeon contains ghosts that can only be damaged by weapons with the holy element. You do not need to kill any to get out, though it makes life a lot easier if you can.

Random facts

In order to progress deep into the dungeon, you must play the second song on the piano found in the left wing.
Many miniboss around here.
Equiping an Elven Mantle (Elf's Mantle in translated menu) makes the zombie girls unable to catch you. This item is strongly recommended since the zombie girls can drain your magic and increase your EX, making your character incredibly vulnerable.
Chests can be found in rooms throughout the mansion. Their loot appears to be random and either dependant on your character or generated when you create your first character - it has been found to vary between playthroughs but will always give the same items if you save scum and open it again. The items are often high quality such as Kyogin's Gauntlet, a Hydra Suit or even a Slave Collar.
The boss chest can have some nice items in it, including an Ogre Shield or an Aegis Shield (nulls physical/magical attacks, respectively, but reduces movement speed) and even a ribbon (nulls all status effects). If you have save everywhere turned on, you can save scum opening the chest until you get the item that you want.

Delta horse traps are found throughout the dungeon, most commonly on carpeted areas. They dran your mana, increase your EX and cannot be avoided.
Items known to damage the ghosts :
- SilverBraid (two handed sword)
- VampireKiller (whip)
- Shadow Daggers
- Silver Dagger
- Star Bringer (1-handed sword)
- Mace (AD)
- All one-handed weapons as long as the Holy Ring is equiped on the other hand.
  - (Contribute ! add more as you experiment !)

There's a priest in the right part of the mansion. Talk to him to be able to get to Avalon; he also gives you a Soul Jar 8.
- In Avalon, you can talk to the nun outside the church to get a gold reward and unlock Lionel. If you return to the forgotton mansion, you will find the priest dead.
- Pray for his soul to get a noticeable amount of experience.

If you check the dog house near the mansion entrance:
- You will autolose the boss battle
- You will be transformed into a cat if your character supports it (e.g. Young Rydia and loli Nakoruru)

Losing to the boss with the fairy and Nakoruru will transform your character into a plant girl.
If your character is transformed, you can talk to the boss to get a masochism piercing on your clit and bell piercings on your breasts.
You do NOT need to fight the boss to escape.
