Expoint Cost: 3
Anytime you are wronged, you insist on obtaining your revenge. You always hold a grudge, and sooner or later, you will exact your inexorable retribution. While this may take the form of anything from relatively harmless practical jokes to the destruction of your target's relationships, business, or life, what you truly live for is to stand triumphant over their helpless form at the end of your next combat. Whenever you fight an opponent you have fought before, you receive a +2 bonus to your attack rolls.
