mathematically optimized for heat (beam mode not incarnon)
for evolution, important one is +20% status chance
and ik gshot is bugged and less efficient but its still the highest dps option bc it has alot of status chance
if u dont want to use primed bane, next best is normal bane, third best replacement is fire rate, but if you want to save ammo then the fourth best is [Hornet Strike]

other test: (purple is current build)

^"crit + x evo" means i swapped out gshot + [Scorch] for primed crit mods and used x evo (all are assuming paladin virtue +1x crit multi in this img)

guide is wip
tldr is beams benefit from multishot twice on status effects and so if u do the math u find that status chance is much more useful than crit, and bc of this heat status procs give a lot more raw dmg than the base weapon and scale infinitely so in the end this will give u the highest possible dmg/s

i used my heat calculator to find optimal build (heat dmg scale infinitely, so modding for heat dmg gives us the highest dps in the end)
