Larva Deletion [Protea]:
This build revolves around using Larva to cluster enemies into one area and using [Blaze] Artillery to swiftly delete them. [Blaze] Artillery has punch through and deals more damage per enemy hit. Therefore, it can ramp up it's damage extremely quickly when enemies are clustered into a ball.

[Umbral Vitality] and Arcane Grace are for extra survivability. With the extreme damage stacking from [Blaze] Artillery, I've found the damage loss from using defensive mods is insignificant. These can be exchanged to suit your play style however. The high duration and range are what makes this build viable, so maintain those stats.
