I said it badly. It does deal the damage. 1 level higher would work. Edited version:
Disrupting spell (Metamagic)
You gain the ability to confuse enmies with your dazzling magic.
Ability to cast 2nd level spells (any type)
Once per day, you may specify one spell that deals damage to disrupt your opponant. You and your opponant make opposed ability checks (spellcasting ability of the caster, IE Intelligence for Wizards), if you succeed, the opponant is blinded for one round, in addition of being dealt the damage.. Prepare spell as if one level higher.
Oh yeah, and you have my permission to use it.
