You can convert mind-affecting magic to necromantic power capable of controlling undead.
Prerequisite(s): Knowledge (religion) 6 ranks, Spell Focus (necromancy).
This feat only works on mind-affecting spells. A threnodic spell affects undead creatures (even mindless undead) as if they weren’t immune to mind-affecting effects, but has no effect on living creatures.
MP Increase: +2 (a threnodic spell costs 2 additional MP more than the actual MP cost of the spell.)
Normal: Undead are immune to mind-affecting effects.
