So yeah, how are you supposed to be able to beat Highlord Omokk? I have tried focusing him first, but he is just too tanky with massive heals from the mage, I have tried to focus his adds first, but then he just starts spamming huge aoe every round. Not to mention his stupid unavoidable insta kill ability with way too short cooldown.

Old Guardian has guides on everything and my go-to for all things Mercenaries. He’s awesome.
