Never having used my Fire-Proof Roach before, I thought I’d have some fun with Apocalypse. Starting with the roach, I did Apocalypse and one Hiss before switching to my Flat-Tooth Calf. All that’s left to do is survive on the calf or the Icespine Hatchling until Apocalypse procs. Unfortunately, Apocalypse never happened. The Calf killed those little rats before the end of 15 rounds. So, basically, solo this one with a Flat-Tooth Calf.
