As to why Bethesda even implemented such ridiculous killcams for magic based kills is ridiculous. The killcam for magic based kills is basically a third person view of your character casting the spell you used to strike the final blow to your opponent- this just seems as a lazy and rushed implementation as people seem to have been complaining that there was a lack of magic based killcams in Skyrim.

I have but one request: update the seemingly lackluster killcams to worthy of a mage.

For Fire based Destruction spells, perhaps the targets blood would boil, leading to them exploding, leaving blood scattered across the area.

For Frost based Destruction spells, perhaps the target could freeze and become immobile, then shatter into multiple units of ice across the area.

For Shock based Destruction spells, perhaps large bolt of lightning could drop down from above the target, leading them into some kind of paralytic seizure, then death.

Any other suggestions will be welcomed, and those posters will get a bottle of Skooma (limited one per poster).
