(Metamagic)
You can convert mind-affecting magic to necromantic power capable of controlling undead.
Prerequisites
Knowledge (religion) 6 ranks,
Spell Focus (necromancy).
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. 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.
