As the title suggests I just killed the Patriarch on Catacombs without him healing and the trophy didn't pop up. As the video shows I was playing on normal with 4 waves and we never let the Patriarch heal, I cut him off out of pure luck to reroute him into the group where he got finished off but he never healed. The official description for the trophy doesn't state what difficult, map, or wave length. Just kill the Patriarch before he has a chance to heal, I did that, where is my trophy?
