Deafening Spell

(Drow of the Underdark, page 49, DnD 3.5)

[Metamagic]

You can modify a spell so it deafens targets

Benefit

You can alter a spell that deals damage to foes so that any living creature dealt damage by the spell is also deafened for 1 round. The effects from multiple deafening spells do not stack. A deafening spell uses up a spell slot one level higher than the spell's actual level.
