Looking for a Defender ability for my oRPG

[marvey323]

Every hero starts off with 3 abilities, accumulates more later on.

The two I currently have lined up include:

1 - Call of Might (works like Axe's Berserker Call from dota, it adds defence and taunts the enemy)

2 - Miracle (a passive spell that has a chance to increase the defender's health per second when hit (lasts for 5 seconds) and increase armor also during that time.

So I need a third spell that will be the hero's offensive spell. Something that he can use to solo farm if there's no group to tank mobs for.

What I have already used (dont need any of the following below):
- Throwing weapons at enemies (axes, etc)
- Critical-type ability that has a chance to deal double or more damage to a unit
- Cleaving type ability
- Ability that increases attack speed or attack damage (I've reserved this for my support classes)
- activate/deactivate type ability that does any combination of the stuff I mentioned above.

So yeah, looks like I ruled out a lot of stuff.. is there any unique-type ability left I can give this defender to damage creeps with?
Any ideas welcome.
