Added new Roshan ability Roar of Retribution. If attacked by the team that last killed him, Roshan will release a roar that is heard globally, damages all units in 900 AoE and applies a debuff on them that increases incoming damage by 25%. Triggers when Roshan’s health drops below 80%. Damage: 50. Damage Bonus per Minute: 10. Debuff Duration: 8s. Cooldown: 20s

This is the most interesting comeback mechanic I’ve seen. I’m not sure it will help much, but if someone is trying to sneak Roshan I can definitely see scenarios where it will come in big
