Flurry

Grants one additional melee attack per round, but at a penalty to attack and defense. The penalty is decreased as the feat is improved upon. The penalty is applied to every attack that round. Extra attack does not stack with Burst of Speed.

When wielding two weapons, this extra attack only applies to the main weapon (simply: only damage from the main weapon is applied if the extra attack lands).

Level 1: Defense Penalty = -2, Attack Penalty = -4

Level 6: Defense Penalty = -1, Attack Penalty = -2

Level 12: Defense Penalty = 0, Attack Penalty = 0
