All right, I'll make a list.
Incinerate-Does large amounts of damage over time and causes burn effects. It can also be used to weaken and destroy support pillars on buildings (making them fall), light campfires, create fireworks, get rid of trees, and if you want to cause a forest fire for whatever reason.
Lightning Strike-Shocks the enemy to keep them in place, doing a small amount of damage over time, setting trees on fire, and ridding yourself of groups in water.
Telekinesis-To lift objects and pull/push them in any direction. Can also be used to rip weapons from your enemy/allys' hands, pinning enemies to high places (this also requires a sharp, throwable edge), and changing the state of objects.
Absolute Freeze-allows you to freeze enemies, water, and the rest of the environment. In addition, you can shatter any of the aforementioned objects with your weapon(s).
You know, spells lke those.
