New Quest’s Added in version 2.01
Quest: Man Cave
Activation requirements: Bat Breeder at full affection, all three “exercise” devices installed in your dungeon.
Location: The Tower of Dread
To unlock the full affection level of your Bat Breeder, you will need to purchase the improved rations and living accommodations from your desk in the bedroom. There after keep giving her orgasms until she maxes out. (should take up to 12 orgasms if you are at level 0). When returning her to the cage at full affection value, the MC will start feeling guilty of keeping her locked up and decides to upgrade the dungeon. You will need furniture (see Marcus, the carpenter) and an outfit for the Bat Breeder (see Edgar, the tailor), it is the leather bikini. Once purchased, return to the tower and set it up. Now you will have a place to relax. Which reduces fatigue and heals the character by a small amount at the cost of an hour. If she’s horny, the Bat Breeder will keep you company on the couch.
