For all players level 500 and above: We have just released a new Attack option in Fights, the Power Attack. Fighting against other Mob Bosses fills your Power Meter, where a Fight Win will fill your meter faster than a Fight Loss. Once your meter is full, as indicated in your Fight response, you will see a new Power Attack button. As it stands the Power Attack will cost you 5 stamina with a much higher experience yield than doing 5 regular attacks. Statistics on the Power Attack feature are available on your Profile page. If you experience any issues, have questions, or feedback on this feature please post it here.
