My Cinta build for my Banshee with 3 purple tau shards - bonus electricity DMG on primary.

Overframe doesn't calculate the bonus DPS from acuity mods, so it's best you try it out in the simulacrum.

(Updated) V1.1
Replaced gaz with electricity for more mod slots, allowing me to add [Rifle Elementalist], [Galvanized Aptitude].

We still have the benefits from 3 purple tau archon shards +electric DMG on primary.

If you don't have longbow sharpshot at least rank 2 or 3, it's best to use primary deadhead.

V1.0
Mods alternatives

1. Hammer shot --> bane mods, riven
2. Primary acuity --> galvanized hell
3. Serration --> [Galvanized Aptitude] (if you have an external primer for "gun CO" like diriga, panzer, hound, predasite)

Arcane alternative:

1. Dead head --> longbow sharpshot
