You can convert mind-affecting magic to necromantic power capable of controlling undead.
Benefit: 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.
Level Increase: +2 (a threnodic spell uses up a spell slot two level higher than the spell’s actual level.)
Normal: Undead are immune to mind-affecting effects.
