galvanized scope have individual counter per stack and aoe cant trigger the bonus (you can with gas/electrical proc, but the proc must come from a headshot) so fuck that mod

vigilante supply is here to augment your crit tiers (on incarnon your at 208% crit chance, so orange crit garanted (tier 2) with 8% of red crit (tier 3), so with the mod you have ~13% of red crit and 0.4% chance of a tier 4 crit)

Incarnon choice :
2) Riddled Target (Damage +6 ; On Puncture Status Effect: +25% Multishot for 8s. Stacks up to 4x)
3) Extended Volley (Magazine Capacity +15) (it's my preference, you can choice either)
4) Critical Parallel (Critical Chance by +24% ; Critical Damage by +0.2x)
