Table of Feats
As a move action, the character may spin his two-handed weapon to increase its power. This adds +1 to the damage roll of his next attack. The character may swing the weapon for as many round as he likes, but each spin provokes an attack of opportunity. He gains a +1 to his damage roll for each consecutive successful spin, but the attack must be the next action after a swing. A character using this feat adds a maximum of his Strength modifier to the damage roll, regardless of how many spins he made.
Gunther, a level 1 fighter with this feat and a Strength of 16 spins his greataxe as a move action while facing a goblin. The goblin gets an attack of opportunity but misses. In the same turn, Gunther uses an attack action to attack, and gains a +1 bonus to damage. If he had used two move actions to spin, he could have attacked his next turn with a +2 damage bonus. If he had used two move actions this turn and another move action next turn to spin, he could have attacked on the second turn with a +3 damage bonus. He could spin for longer than that, but his extra damage would not be more than +3, his Strength modifier. If the goblin moved away, Gunther could use his attack of opportunity to expend his damage bonus. If he let the goblin go, he could move to follow, but he would then lose all accumulated spin bonuses.
