Okay here's my other request, posting it here anyway.
Fear - AoE (no damage) where enemy units run away from the caster in fear for X seconds.
Level 1 - 5 seconds
Level 2 - 10 seconds
Level 5 - 25 seconds
If you've played WoW it's like the warlock's fear spell.
You can use whatever icon, I don't mind. But if you want you can just use the banshee's possession spell.
