Fell Frighten

(Libris Mortis: The Book of the Dead, page 27, DnD 3.5)

[Metamagic]

Living foes damaged by your spell are also shaken.

Benefit

You can alter a spell that deals damage to foes so that any creature subject to fear effects and mind-affecting spells and abilities that is dealt damage also becomes shaken for 1 minute. A fell frightening spell uses up a spell slot two levels higher than the spell's actual level.
