I'm currently lava soaking my brute. Been in for about 3 hours and it's actually working with my health holding pretty steady at about 1/3 with no auto heals. I'm sure it will take a while to get all the badges but it would never happen by just playing. Currently taking 12000 damage per minute.
I'm sitting in the exact same spot as the picture with six spawns marching in place. My heal shows +857 for all that it hits, but my total in the badges window isn't moving at all. What's wrong?
