This build basically lets you create a [Tigris Prime] that fits in your melee slot and trades lower damage for infinite range, infinite ammo, and an EXTREMELY rapid rate of fire. This build eats armor in seconds with corrosion while stunlocking with blast (each of the 10 pellets has a 100% condition chance, so you trigger a proc of each multiple times a second); after a couple hits, your opponent will be impacted by 5 conditions, which buffs your damage by 300% due to [Condition Overload], and have no armor left.
