This build focuses on spreading CC and status on the Steel Path.

• Use your Melee with [Condition Overload] . You should not rely solely on your abilities to kill.
  Catalyze can still kill with 40% strength but use your weapons too.
• Use Electricity on 2. You will use this a lot for CC and Status
• Use any unused element on 3
• Use Electricity on 4
• When in doubt, just use Electricity on every ability
• Get companion (that can equip guns) with Synth Deconstruct
  I recommend using Dethcube with Energy Generator
• Use [Helstrum] with unused elements of your choice and high fire rate

Resonator is pretty OP. You may want to use another ability for survivability if you don't like it.
Aura can be anything
