Combat Trump
Expoint Cost: 2
Some call you an opportunist. Others call you a shifty, mean-spirited bastard. Just about everyone would rather call you ally than foe, however. You are an expert at taking advantage of the surprise and shock of foes in combat. Whenever you attack an opponent who has gained the wide-eyed condition, you get a +2 bonus on the Damage Roll.
While not incompatible with Hyperactive, it sure makes things hard on you when you can't sit still long enough to spring your deadly traps. Also, taking Stupefied means you can dish it out, but you can't take it.
