Have you ever wanted to shoot a nox once, and watch them disintegrate? press your alternate fire button and watch the heads roll!
The progenitor element is ultimately up to you as the player, but I find the blast + corrosive combo to do very well.
[Tactical Pump] is there so that we can keep using the alternate fire as quickly as possible.
The 5 forma are primarily 4 "v" polarities, and 1 "D" polarity. if you feel different forma / polarities work for you, then I'd love to hear about it :) enjoy the build!
