Umbra Forma needed if using riven
This build is slightly lacking in base damage which will make getting the stacks for galvanized a little difficult, but if you run Arcane Fury it becomes much faster
Condition Overload seemed to pretty much be overkill/unnoticeable, but you would replace [Organ Shatter] and additionally run Tenacious Bond on companion
Ideal Riven (replaces Organ Shatter):
+Status Chance
+Critical Damage
+Critical Chance
-Harmless
[Organ Shatter] can also be replaced with Weeping Wounds
Ideal Riven (using Weeping Wounds & replaces Volcanic Edge):
+Heat
+Critical Damage
+Status Chance
-Harmless
If no bane applicable use [Gladiator Might] or [Primed Pressure Point]
