STRATEGY AND TIPS:
For the most part you're freezing the red health enemies and taking them temporarily out of the fight preventing them from firing or from performing any kind of movement. Which allows you to focus on higher priority targets like the anointed or if you're fighting the remnant you focus on the observers.
Cryo trap is useful to zone out red health enemies from flanking you.
Overload can prime and detonate your energy drain and vice versa however overload has a shorter priming window you have to factor in.
Cryo beam has a cooldown depending on how long you're casting it. So don't cast cryo beam for longer than you need to especially if it's just like 3 or 4 enemies.
