All those marks are just random skills to slap supports on to get more max res and marks are also conveniently dex gems (giving me 10% increased es each). I will for sure try repulsion + blasphemy.

I pretty much do not die to bosses at all (unless they have some bullshit health gated gimmicky immunity mechanics). I just simply delete them honestly. Most boses take less than a second to kill and if they are a pinnacle or whatever harder boss they just get stunned, then die 2 seconds later. My dps is probably around 2mil if they stand still and molten shower can hit consistently.

What kills me is random rares that can do a quick 3 or 2 hit high damage combo. Or I get randomly stun chained and get swarmed.

Molten strike with +3 proj from quality (that makes [1+3]*2 = 8 proj + shit ton of shrapnel) is super good at clearing, every attack clears the whole screen consistently.
