Obviously, with my super-hero talents, it would be something to do with making lightbulbs explode.

I'm serious. That is my super human ability-- I can make light bulbs pop by merely flicking the switch, if even that.

Ooh, I've got it--conjure up a lightbulb, float it over to the enemies' side, and make it explode, for radiant damage-- most to the thing it's closest to, then lessening as it goes away-- random targeted, but obviously it's best if the enemy is in the middle.

Maybe you can power it up by adding lightbulbs, perhaps adding some elemental light (or gravity for blacklights) and different types-- fluorescent will be a small nova bomb like thing, incadescent will be fire type damage, low-pressure sodium whatever lamps can inflict statuses+small damage, and halogen would. . .what exactly is a halogen light?

Obviously you'd have to find all the types of lightbulbs, or steal them before they'd be selectable. Heh, miniquest time!
