I was watching a few action movies, and I think my trog with a combat ax would like something like this.
RALLY!
Cost: 7 per level (1 to 3 levels)
We all get pumped when we put a fragger down. Some get even more pumped when they do it the hard, handheld way. When you deliver the killing or knock out blow with a melee weapon, you may immediately heal a number of stun boxes equal to your levels in this quality as you are filled with adrenalin from the kill!
Thoughts?
