40 CLAY LABORATORY. The walls, ceiling, and floor are made of moist gray clay. Five rough humanoid clay statues are here, with their backs linked to the wall by inch thick wire coils.
The clay statues are actually an experimental form of vat creature and the coils carry vat media from a source in the wall to nourish them. When the room is entered, they will activate, opening their eyes and each randomly choosing one of the intruders to mimic. The creatures will eject their nourishing fluid coils. It is possible for more than one of the clay creatures to choose the same character.
If a spellcaster (cleric, magic-user, or subclass) is chosen, then the vat creature will turn into a type 1. For all others (fighter, thief, monk, etc.) it will be a type 2.
Type 1 Clay Creature (AC 7; MV 9"; HD *; #AT 0; D Nil; SA Spells; XP varies)
Type 2 Clay Creature (AC 6; MV 9"; HD *; #AT 1; D 1-10; XP varies)
The vat creature will take on the rough appearance of the chosen character, appearing to hold the same kind of weapon, for example, though it will be not fully formed. They will have the same number of hit dice less one than the chosen character. Hit point type (d4, d6, d8, d10) is based on the mimicked character class. Type 1s will have access to the same spells as the mimicked character. They do not need to use components to use the spells.
