a quick build for max dmg, i don't get why people [Hate] on it fr.
incarnon form big boom will do atleast 2mil heat, with evolutions even more idk
perk 1: fire rate
perk 2: reload speed
perk 3: u can choose between quicker incarnon charge or punch through on kill
perk 4: funny stackable crit chance and crit dmg (this is additive 250% on both, shit goes crazy)

idk about much else, gotta try the build for myself.
edit: tested build, found out 2 things.
1. HOLY SHIT THE DMG IS CRAZY
2. cascadia flare does more dmg, and is overall just easier to upkeep imo, but overall its up to u. if you dont have a flare arcane ranked higher than merciless, stick with merciless.
build good, and build still works. too bad the forma is annoying to farm
