Alchemy.
Traditionally, it's a skill for mages. It'll allow you to create potions AND poisons. The latter are one-time effects on your weapon of choice. By mixing "weakness to ____" and "___ damage" effects, you'll add extra damage to your sneak attacks, and it often means the difference between almost-killing something and barely scratching something.
Note that to get destruction to work as you described it, you generally need to know exactly what you are doing. Destruction Magic can be underpowered, but those who know how to use it are devestating at range.
