wanna step into a room and delete everything at once? use this build
Why Not Viral?
in my field testing corrosive works better against grineer/corrupted than viral maybe it would be different if we had [Hunter Munitions] for secondaries( [Hemorrhage] doesnt work for [Akarius], fire rate is too high and the radial attack doesn't deal impact dmg)
both of those mods are everywhere but [Galvanized Shot] does not work on aoe weapons, it only affects the direct hit not the radial attack which is where most of the damage comes from.
& if you switch [Hornet Strike] with [Lethal Torrent] you'll get 1.5 million burst dps though the average hit drops to 286k from 334k which means you need to shoot more to kill some tough enemies and that's not what we want
Arcanes
cascadia flare gives a bigger buff than merciless but sustaining it can be more difficult since you can lose all of your stacks at once but with merciless you only lose 1 stack at a time, test them out to see which one you like better
as for warframe arcanes use arcane awakening & avenger the other pistol arcanes are useless for akarius you're not gonna get headshot cause you're not gonna be aiming and fire rate wont matter cause you're shooting 1-2 times for most enemies and the current fire rate is good enough for that
QOL
this build is strong, i'd even say too strong for most missions that players will face (not everyone does level cap runs and if you do look for another weapon that scales better) so for average missions & early SP i recommend using [Primed Fulmination] instead of faction mods since you get to kill more enemies at once and have an easier time shooting enemies through walls, you can literally look at a spot with 20 enemies shoot once and watch the red dots disappear on the map.
beware that the stagger will be crazy you're either gonna want to use a tanky frame thats immune to stagger like [Revenant], [Nezha] etc... or [Primed Sure Footed]
Rivens
for rivens replace the faction mod or [Pathogen Rounds] if it has toxin. best stats you can get are either cc, cd, tox or dmg, multi, tox ideally with a harmless negative like -zoom or - impact
Build Variations
Corpus
as long as you take toxin you're gonna be fine against corpus, even though half the dmg is gone you can still take this to sp after all corpus and infested are the easier captions

Murmur
both corrosive and radiation are useful against murmur and with the new mod accelerated isotope having both in the same build is now achievable (yes you can take this to netracells)
