Fortress' Other Abilities

Packmates
Heroic Perk
When Fortress is near an allied hero, he will move faster after 1 second. He will maintain this move-speed bonus so long as he’s alongside any allied hero.
Law of the Claw
Slot B
Fortress claws his target for crystal damage and causes it to bleed. Bleeding targets take 25 +15% of crystal power as damage every second. Attacks from Fortress and his allies have +10% lifesteal against bleeding targets and increase bleeding by one stack. Upon reaching 6 stacks, the target is dealt a burst of damage based on its max health, is slowed by 30% and receives mortal wound (-33% healing).
Attack of the Pack [Ultimate]
Slot C
Fortress howls, gaining increased health and attack speed and calls to him a pack of wolves. Each pack wolf seeks out a different enemy hero. These wolves apply bleeding with their basic attacks.
