Strikes with your mind blade are particularly devastating to undead.
Prerequisites: Base attack bonus +6, psychic strike +2d8.
Benefit: Instead of charging your mind blade with the energy from psychic strike, you can instead imbue your mind blade with positively-charged energy. Each d8 of damage normally dealt from psychic strike is instead effective only against undead.
Normal: Psychic strike can only be used on living, non-mindless targets.
