Hello I noticed there has been some interest in shockwave totem builds lately.
I created one that is focused on bossing but has a mapping variant as well.
Surfcaster is nice with the fishing rod and some sort of explode. It is really easy to scale explosions and have the chaining effect for easy mapping. And the single target damage can get ridiculous with decent investment.
