Build focused on maximum dps to barely match the Acceltra's power

Hunter Munitions doesnt synergize well with the build ONLY if you are not maximizing the fire-rate, it is possible to swap blaze with it against grineer match-up but you will lack a bit of damage against anything else despite that armor is the only type of damage reduction
Going for heat DOES reduce your slash weight, but for most casual gameplay you will still get some procs... For the trade-off that you will be dealing more direct damage to acolytes and highly shielded targets

Im aware that arcanes compensate for the fire-rate and that free up from [Shotgun Barrage], however... My builds are made without depending of them)

I've used [Primed Point Blank] on this build before being updated... But i decided to start using [Galvanized Savvy] along with [Blaze] to add an rather higher dps despite [Galvanized Savvy] not being able to be used on the AoE part of the gun, this is actually compensated by both [Blaze] and primary merciless... So, you arent losing any damage at all

If you prefer in favor of less damage loss, you can swap merciless to deadhead even though it will take some luck to get headshot kills

Any other possible arcane options?
Nah, not really...
P-Frostbite is never an great option despite the primed mods
S-Vendetta could be good, but you dont ever really need it plus kinda risky
P-Exihilarate is... Free energy 8)
