Hero Special Ability's.

[Dameon]

So I am making a Custom Hero Team Survival/Def map. I want to add some thing special to the hero's so each will have there special ability other then the custom abilitys. For each ability type there will be 3 heros, 1 str, 1 agi, 1 int. Thing is I need ideas for these abilitys, I need 12 total, here is what I have so far.
01. Reanimator, % chance to spawn a creep the type of the one you killed to fight for you.
02. Regenerator, Higher then normal hp/mp regeneration.
03. Reencarnation, Faster then normal revival.
04. Evolution, ever # of creeps killed gives +1 to the primary attribute.
05. Shield, takes reduced damage.
06.
07.
08.
09.
10.
11.
12.
