Attacks from Beastmaster or a nearby unit he controls will cause him bang his drum, dealing damage to nearby units and healing Beastmaster and units under his control for a portion of the damage dealt. Every attack decreases the interval between drum hits down to a minimum of 0.5s between hits after 20 attacks. If no attacks are made, the intervals gradually increase. Using Primal Roar counts as 10 attacks.
Increases Hawk duration by 5s and summons an additional Hawk.
