A build maximizing damage vs Arbitration Drones assuming a +Damage buff([Chroma]), +Elemental buff([Oberon], [Volt], e.t.c.) and +Faction buff([Rhino]) on the squad.

Arbitration Drones inherit faction from the mission (i.e: they count as Infested for faction damage modifiers if the mission is against Infested). So swap the faction damage mod to whatever enemies you're up against.

The least important mods are Hammer Shot and PFast Hands. They're first priority to replace with a Riven or mods for non-meta squads.
Riven stat priority: CC > CD > MS > Reload > Dmg > Elemental
