I noticed there are no actually viable builds for this primary kitgun, so I decided to share mine. TL;DR: Think [Kuva Bramma], but humble and friendly to use.
Just destroy everything, guys. That's the perfect build for my favorite primary so far. There's some good 120 hours of testing, and this shit packs a punch.
Any kitgun arcane will do, but none are very good. Primary Merciless is a monster tho, literally doubling your damage.
Try with [Wisp] for ultra fast spam, or with Zephyr for THICC crits.
Replace Vile Acceleration with riven if you have one. You want on it Crit Chance/Dmg, plus fire rate for spamming doom.
Have fun.
