Maximises status chance (since 100+ status allows for additional status procs), uncapped multishot, and damage types.

Exilus can be changed with [Eject Magazine], [Primed Pistol Ammo Mutation], [Reflex Draw], [Suppress], [Trick Mag] to taste

Replace [Embedded Catalyzer] with Stunning Spee, or a 60% mod ([Carnis Stinger], [Jugulus Spines], [Saxum Spittle]) for uncapped status if you don't use abilities

Look for riven with Multishot >> Status Chance > Fire Rate >> Punch Through and replace to taste (I prefer replacing [Embedded Catalyzer] or [Seeker])

Secondary Dexterity helps slightly when using a melee for DPS, useless otherwise.
