A shaman surrounds herself with the spirit of battle. Allies within 30 feet of the shaman (including the shaman herself) receive a +1 morale bonus on attack rolls and weapon damage rolls. At 8th level and again at 16th level, these bonuses increase by 1. The shaman can use this ability for a number of rounds per day equal to 3 + her Charisma modifier. These rounds do not need to be consecutive.
