Thunderbolt

 is an Expert-level Destruction spell in The Elder Scrolls V: Skyrim. Unlike Sparks, which fires a jet of continuous sparks, Thunderbolt must be momentarily charged, then flung. Casting the spell deals 90 points of shock damage to Health and half that to Magicka. Dual Wielding this spell causes a unique animation.
