I think it's safe to just say it's dead... From my knowledge its 3 ribbons (liberal read = each doing full attacks at the casters BAB) (conservative read = readying a touch attack at BAB)+casting stat vs touch AC each hit doing 5d10 DMG each action the Elemental takes, i.e. Were it mine potentially (liberal 90d10) (conservative 30d10) if all touch attacks hit. It's probably one of the badest damage spells out there.
