The game's hero schedule puts Eorin, the Wilders spear Ranger, into Companions on 3 November, with version 2.306. He plays as a burst assassin: at the start of a fight he goes straight for the enemy with the highest Attack Rating, and his ultimate joins his split spear for four heavy strikes that also spread his poison debuffs. His full Companions kit is already up on his hero page.
