Frost from a distance: Hit them with two huge spikes with a 'one-two!' and they freeze
Frost up close: Grab their face and freeze their whole body
Fire from a distance: Make them explode, lol
Fire up close: Grab their face and make their character model turn into those 'burned corpses'
Shock from a distance: Make an actual lightning bolt come from the sky and turn them to ashes.
Shock up close: Grab the target's face and shock their whole body until they turn to ashes.
Bethesda probably won't do this, I know. Maybe the modding community can give destruction some finishing move love :]
