tldr:

• can replace vile acceleration with damage mod if need ammo economy (mod list below)
  ㅤㅤ- can especially do this if you have external fire rate from somewhere like reinforced bond
• primed cryo is better than rime rounds ONLY against really weak stuff where honestly it wont matter anyways so save ur forma (rime is better in sp)
• if you dont have weapon arcanes, use serration over bane (always)
• else, if you dont have primed bane use normal one but if you cba then use serration aswell (alternative options below)
• slash calculator: https://docs.google.com/spreadsheets/d/1LTuXewHeKYDBMguM1RE2i-zY2p1WnCYpvOK61kmKIEo/edit?usp=sharing

viable mod alternatives:
serration, bladed rounds, hammer shot
ㅤㅤ- serration is most consistent option here (amalgam serration works nice with this gun too)
ㅤㅤ- bladed rounds is highest possible dps (when everything is stacked), but it is weaker initially and annoying to use
ㅤㅤ- [Hammer Shot] is also viable, I think it may even be better than bladed rounds in some situations with the status chance, + its not annoying to use
ㅤㅤ- hellfire can also be used however it doesnt add anything to slash damage and takes away from viral procs/s, but could be ok against weaker enemies

other:

• if no primed ammo mutation just use normal one (or vigilante supplies, but its less ammo)
  ㅤㅤ- can use vigilante set on companion weapon (applies to your weapon) for extra dps
• galvanized scope is bad (dont work on aoe or slash + too hard and cba)
• galvanized aptitude bad because gun is aoe and it doesnt work on aoe
• [Firestorm] is bad because its a % increase and acceltra has a small aoe therefore it increases only very little in terms of actual volume
  ㅤㅤ- can still be nice QoL if you dont need the dps tho
• set sprint as toggle (and keep it toggled on ofc) for permanent reload buff (hidden passive of [Acceltra])
