Heat + Viral + Rad [Coda Pox]
Work's very well with a [Gyre] build of constant electricity procs from abilities 3 and 4 utilizing both augments for them.
2 Yellow Tauforged Casting, 3 Purple Tauforged Ability DMG on electricity.
Gas from Pox may trigger the ability 4 Electricity proc at least 2-3 times, so it's fun to spam.
Heat proc for Armor stripping up to 50%
Viral for DMG vulnerability against Health at 10x stacks = 325%
Radiation proc to confuse enemies.
Fortifier is there to help build Overguard from eximus enemies for [Gyre] as an extra layer of survivability as [Gyre] relies on shield gating. You can swap it out for Enervate if you feel it's unnecessary.
