Primal Regression

This creature is a ravening monster — savage, bloodthirsty, and brutish. Until the spell ends, it has all of the following benefits and drawbacks: Its Intelligence and Charisma scores drop to 1, and it is unable to cast spells. It takes a –4 penalty on Will saves. It gains a +6 enhancement bonus to Strength, a +2 natural armor bonus to AC, and 2d8 temporary hit points. These temporary hit points disappear at the end of the spell's duration. When the spell ends, on the next round this creature must succeed at a Will saving throw or take 1d4 points of Intelligence drain and 1d4 points of Charisma damage.
