This build seeks to solve the problem of how to gather 8+ enemies together so that you can charge them and get insane amounts of Iron Skin health.
I replaced Stomp with Larva, since they are both crowd control abilities. You can also replace Roar, if you want to keep Stomp, but I feel that Roar has more benefit than Stomp.
Additionally, you can use Larva to group enemies together for massive aoe damage with Roar activated.
[Iron Shrapnel] and [Saxum Carapace] can be swapped out for other cards of your choice.
