Assimilation (Su) If a soultaker spends 10 minutes consuming the body of a Small or Medium humanoid with a number of Hit Dice no greater than twice its own, the soultaker consumes that humanoid's identity. The soultaker loses all abilities and becomes a simulacrum of that humanoid, as per the simulacrum spell (caster level equals the soul taker's Hit Dice). For as long as a soultaker is a simulacrum of that creature, that creature cannot be restored to life by any means. The soultaker can permanently revert to its normal form as an immediate action. The soultaker retains any damage or other harmful effects it suffered while in simulacrum form when it reverts to its normal form.
