Full CC builds, suitable for almost anything. But particularly good at defence missions, or anything that requires crowd control.
This build provides: self infinite energy and sustain, 42m radius large crowd control, nearly immortal (3 fail-safe mechanics: [Garuda]'s cast animation (iframe), augur mod for shield gating, [Quick Thinking] for staggering).

The key is to use gloom with infinite energy to CC and do whatever you need with those stationary mobs.
You may replace any skill other than bloodletting with gloom, up to your preference.

• Make sure to trigger glowing power before cast gloom, you need at least 272% strength for 95% slow, and that basically 'freeze' the mob.
• Replenish energy by using bloodletting, and you can just attack anything to get your HP back.
• Avoid any Corpus 'bubbles' or fall through the map, it will cancel your gloom. Since this build does not have any duration, it's going to take around 30 seconds to reach 42m 'freezing' radios again.
• Note invulnerable mobs are not subject to gloom (ex: mobs with arbitration drones, Kuva [Guardian] and etc.)

Operator with healing class is recommended but not necessary.
