Hitting a Heavy Attack/Heavy Attack Pursuit Skill increases Light Attack/Projectile Skill damage by 12% for 15 seconds, and vice versa. When both damage bonuses exist at the same time, they will be upgraded into Veil of the Willow: Increases the damage of both Light Attack/Projectile Skills and Heavy Attack/Heavy Attack Pursuit Skills. Hitting the enemy with corresponding skills again can refresh the effect's duration; the duration can only be refreshed once every 2 seconds.
