Vengeance!

The Mafia Wars blog just made a post. It sounds like a mighty sucker punch, almost :) 200% attack bonus might could come in handy. Although I usually just move on when I lose a fight!

For three Reward Points, you’ll be able to GET VENGEANCE on your enemy. One click will net you full health, 10% Stamina, and a one-time 200% attack bonus!
