Succubus Tower

First floor
This is where Rinny can be found.

Bath
Lust Doll can take bath here (removes Slimy status effect). If Rinny is presented, this would also lead to a shower sex scene.

Training grounds
Allows to train your Mystic stat, by 3 points per point of mana. Only available if at least one spell is known.

The dungeon
The local sex-dungeon. After completing Freeloader quest, Alissa can be occasionally encountered there, along with Rinny.

Class
Attending class would train Lust Doll's Erotic stat by 15 points, but only once per day. In beginning, Lust Doll has to pick either shy or proud behaviour pattern, which determines available options; the following scenes are available:
 * Masturbating (if "proud" option was taken)
 * Run away (only if "shameful" option was taken; wouldn't reset Lust Doll's lust)
 * Calling Rinny for help (available on both paths, unless Rinny is busy)

Body Workshop
Allows to change Lust Doll's genitals – breasts, pussy, dick, balls. It would cost them money, but they may say that they are broke (regardless of wether it's true or not); this would result in them being sexually tortured and leaved them extremely horny, but would preserve their money.

Library
Allows to train Insight stat, but would raise their lust each time they train here. Up to 21 points may be acquired before lust maxes out.

This is also where Lust Doll may learn about dangers of magic when Rinny insists that she wouldn't train anyone unaware of the risks, by talking with local succubi.

Bedrooms
Lust Doll can sleep here. Unlike most beds, it's not possible to masturbate here. There's also a random chance of night harassment scene when sleeping there, which results in maxed out lust; the scene doesn't trigger if Rinny is following Lust Doll.

Shop
Sells clothes.

Fourth floor
Has only one locked and guarded door, which leads to the Queen's chambers. What's behind it is currently unknown.
