Power

Power represents a pet's raw ability or strength for using damaging Skills. Under Explore, this statistic was called Attack. Power is one of the options you can choose to increase when a pet Levels up. Power can be checked on the Pet Status screen of the Battledome, as well as the Equipment page. Virtually all Weapon type items increase Power when equipped. These increases are percentage based, thus pets with a high Power rating will benefit the most from equipment bonuses.

A pet's Power rating (including equipment bonuses, if any) directly affects how much damage they will do in combat. Skill strength is multiplied by ATK Power for base damage, before interacting with the opponent's Toughness rating. The stat booster Attack Potion will probably be used in some way to increase Power in the future; at present it is still tied to the Attack stat for Explore.
