You get 1 item for free per floor, 1 item behind a locked door (it can actually be ANY item, even stuff like Godhead.
You get a shop with a line of items that automatically refills its wares each time you buy something.
One whore of babylon room holds a surprise. The exit to the next floor opens after you beat the boss waves.
Do 6 floors of this then you get to fight the final boss.
Monstro!
