Strength

From Outwar Wiki

Strength is the system which replaced supplies and cash. A meter now appears to the right of the rage counter, which slowly fills up as you attack mobs in Diamond City or commit attacks on other players, the former giving 1 strength per successful attack, and the latter stripping a portion from the victim and granting 1/20th to the attacker. Strength gives a small amount of attack and hitpoints depending on the character's level and the percentage of strength obtained. The bonus increases with the character's level. Strength is stripped away like experience in incoming attacks and by losing to a mob in Diamond City, but can never go below 0.
