This is a questionable build, or so you'd assume. There are a few things that make it better, though;
- Behold the Adarza Kavat, the Arcane Avenger, the beam weapon fire rate of 12 hits per second. All of these make Hunter Munitions more likely to trigger, which means more slash procs.
- Behold Primed Ravage, which increases the damage of slash procs on crits.
- Behold the headshot multiplier of Primary Deadhead, which further increases slash proc damage.
- Behold Primed Cleanse Whatever Faction You're Fighting, Maybe Swap This For Fire Rate If It's Sentients, which double dips on slash procs.
Also consider pairing it with a high Duration Lavos for increased proc duration, or replacing Sweeping Serration, Vigilante Armaments, or Primed Ravage with a riven with improved stats(higher crit damage, multishot, or slash, preferably with status chance, fire rate, base damage, or punch through as an additional stat.)
If you want viral procs, find them elsewhere. Use a Panzer Vulpaphyla instead of putting them on this gun, it'll do better damage.
