Strike of Might

Level: 2
Duration: 1 round
Saving Throw: None
Normal: You tap into an ally’s damage potential, augmenting her combat abilities substantially.
Your target’s single next weapon damage roll (if it is made before the end of the next round) deals an additional 10 points of damage as it explodes with a spout of magical energy. This damage is not multiplied on critical hits. 
Reverse: You briefly enfeeble an enemy, causing its swings to slow and deal less damage.
Your target’s single next weapon damage roll (if it is made before the end of the next round) deals 5 fewer points of damage as the blow is cushioned by an unseen force. This penalty can reduce the damage to 0, but not below.
