Ulfsaar, the Ursa Warrior is a melee agility hero from Radiant which recently got added in DOTA 2 (12/15/11) update. Ursa is a powerful powerful tank hero with exceptional abilities allowing him to finish his enemies in few hits. He’s one of the few heroes in DOTA who can solo Roshan at early level. With some proper support from stunners/gankers, Ursa can lead a team to the victory. Check the DOTA 2 version of Ursa Warrior!
