Carcinization

You manipulate the target's genetic code and accelerate the inevitable, pressuring the target to undergo carcinization and become a crab. A willing target fully transforms into a crab, as if it had cast Animal Form heightened to the same rank as this spell and using the following statistics. Crab Speed 25 feet, swim 15 feet; Melee Single Action big claw, Damage 2d8 piercing; Melee Single Action claw (agile), Damage 2d4 piercing. Can breathe air and water. Unwilling targets must instead attempt a Fortitude save. Critical Success The target is unaffected. Success The target's body gains minor features of a crab, its appendages turning into claws and causing it to become Clumsy 1. Failure The target transforms into a partial crab-like being, becoming clumsy 1, Stupefied 1, and Sickened 1. Critical Failure The target is transformed into a partial crab-like being and becomes clumsy 2, Stupefied 2, and Sickened 2.
