Urogrim joins the Ogryn Tribes Faction in Patch 4.50 as a Void Support Champion.
Urogrim brings a substantial amount of poisons along with some additional support in a strong single-target heal and AoE continuous heals. A 20% aura for speed in all battles is significant for many early to mid-game players. The main problem with Urogrim is that the cleanse on his A2 is just a single target which may be useful as a spider healer or a Clan Boss cleanse but ultimately will be difficult to find use in most areas. He does however poison far more than most champions in the game which may prove useful in Clan Boss if you can bring the other required debuffs.
He has a fantastic ability to solo farm Dragon 25 allowing you to farm food at the same time as well.
