An extremely simple fairy gun setup. Point it at something and it dies.

To use with:
-Razorwing Blitz, and enough strength in the build so you can comfortably move. For all the firerate.
-Archon Vitality. Doubles your heat procs. Yes it does work on exalted weapons, and is as silly with this as you think it is.
-Arcane Pistoleer. All the bullets, forever.
-Arcane Precision, for that bit of extra damage just in case.

Alternatives:
-Hornet Strike and Barrel Diffusion if you don't have Galvanized mods yet.
-You can swap out crit for a faction mod and another elemental. It does a tiny bit more damage that way, but it's more annoying to use.
-Switch around the elements as you need or like, tho not having Prime [Heated Charge] in there takes out a good chunk.
