The Damage Spell Ideas Thread

The point of this thread is to try and figure out all the different 'types' of damage spells that can be made. Alot of custom abilities in TFT maps are just direct damage spells -- lets see if we can't be a little more creative:

Damage skills:

Direct Damage
Damage over time (poison)
Leeching damage
Ray of damage (shockwave, carrion swarm)
AOE damage around caster (warstomp, thunderclap)
AOE damage around a target
Missile thrown in a direction, can miss
Homing missile, if you run long enough it blows up
Charge skills, the longer you charge the more damage you do.
Trail skills (you leave behind something that hurts as you walk)
High AOE damage, but you get visual cue to get the hell out of the way (flamestrike)
'Burn' another stat doing damage (mana burn)

Do we post ones we have made or just give ideas?
