It would be nice if whe could kill undead when whe use spells/wands from Electroblob's Wizardry.

Alright, I'll look into it.

It looks like Electroblob's Wizardry doesn't really add any holy spells, only fire spells. As far as the fire spells go, as long as they indicate fire damage then it should integrate naturally with the newest version of Consecration (0.0.8) that will be released pending Curse approval.
