Empower allows you to [Reach] 204% power strength for [Gaze] to strip ALL of the enemy armor. This build avoids using [Blind Rage] so you can have good efficiency and duration which make [Xaku] MUCH more comfortable to play.

[Xaku]'s abilities are EXTREMLY expensive in energy and Empower is the only way to avoid using [Blind Rage].

If you wish not to entirely strip the armor, you can just put a not fully ranked [Umbral Intensify] or [Power Drift].

This shouldn't have any survivability issue since everything in a 20m radius is dead but if you feel like it's not enough (it is), you can replace Augur Message with Adaptation.

Start of the mission should be:

• find a decent group of enemies
• Cast 4
• Cast 1
• Cast 2
• Decide a farming spot, Reach your objective
• Cast 1
• Cast Gaze
• Double click on 4 when it runs out, every 40s

This is the absolute laziest way to kill everything including Steel Path grineers.
