When you say 'attacked by the others', do you mean in a similar way to Void's [i]Void Burst[/i] ability, where you'd absorb the damage and then redirect it into other effects, or would it be more a case of gathering Energy to help power your other abilities?

It'd be a marker for an enemy, and every time that enemy took damage, it would increase the combo. 0.5 for standard actions, 1.0 for skills. Or something to that effect, anyway.
