Transformation

You become a fighting machine — stronger, tougher, faster, and more skilled in combat. Your mindset changes so that you relish combat and you can't cast spells, even from magic items. You gain a +4 enhancement bonus to Strength, Dexterity, and Constitution, a +4 natural armor bonus to AC, a +5 competence bonus on Fortitude saves, and proficiency with all simple and martial weapons. Your base attack bonus equals your character level (but not higher than 20), which may give you multiple attacks.
