No base damage mods?
Currently, [Hornet Strike] and [Galvanized Shot] only work on the initial target hit and does not apply to the seeking fragments.

If you have an external method of applying viral e.g. Panzer/Hound/[Diriga] or Nourish, consider swapping [Carnis Stinger] + both viral mods for [Galvanized Shot], [Hornet Strike] and [Anemic Agility].

Boost fire rate with external things like [Reinforced Bond], [Furax Wraith] Amalgam [Body Count], Arcane Velocity.

If you subsume OVER [Noctua] and only use Wordwarden, remove [Galvanized Diffusion] and [Lethal Torrent] for [Hornet Strike] + [Sure Shot] since Fire rate and Multishot do not seem to work on wordwarden.

MOD BREAKDOWN

[Galvanized Diffusion] : mandatory multishot
[Primed Pistol Gambit]: mandatory CC

[Carnis Stinger]: adds status and increases slash weighting to approximately 60% after Viral mods
[Lethal Torrent]: adds fire rate and multishot
Primed Expel: double dips DoT, increasing slash procs by 2.1425x. If you don't like faction mods, use [Anemic Agility] or [Hornet Strike].
