Benefit: While raging, the barbarian is surrounded by spirit wisps that harass
her foes. These spirits make one slam attack each round against a living
foe that is adjacent to the barbarian. This slam attack is made using
the barbarian’s full base attack bonus, plus the barbarian’s Charisma modifier. The slam deals 1d4 points of negative energy damage, plus the barbarian’s Charisma modifier.
Who decides who the spirits attack, and what effects affect the spirits?
The barbarian decides who the spirits attack each round. The spirits are not affected by effects that aid their attacks or damage (such as bardic performance or bless) or penalize their attacks or damage (such as bane or darkness). The spirits always strike from your direction. They do not get flanking bonuses or help a combatant get one.
