In short of it 2-4 seconds to kill groups of enemies

!!! BUT !!!

IF WE ARE TALKING ABOUT SOLO
For what Baruuk is NOT GOOD ON STEEL PATH (if we consider just killing with Serene Storm and losing Restraint) :

• Bosses
• Extermination
• Spy
• Demolisher (on Distruption)
• Rescue

In most cases its because not enough enemies spawn as for Bosses/Demolishers Damage output is just better from your weapons

Desert Wind build to use with this [Baruuk] build

You can supplement this build with Reaper Prime Healing Heavy Attack Butcher for dealing damage while you cant use Desert Wind

For what he is perfect:

• Steel Path missions (exclude the above)
• Survival
• Mobile and regular Defense
• Interception (on small map e.g. Hydron)
• Infested and Corpus (in my experience are best types of enemies that helps lose Restraint efficiently)

Problems starts when you want to use Serene Storm but you build up Restraint too fast and you cant lose it fast enough to sustain Serene Storm
Thats why [Baruuk] is not good for every mission while you stil can do with him any mission + his resistance is pretty big advantage (Lull (press 3) and Serene Storm (press 4) gives damage reduction)

How to use:

1. On begging of the mission cast Desolate Hands (press 3)
2. Find group of enemies and get into center of them (or where they will soon come e.g. cryopod <- defense target) and cast Lull (press 2)
3. Repeat the process until you lose around half of your Restraint (you can lose less but more u lose easier it will be to maintain it halfway in most cases)
4. Cast Serene Storm (press 4) and start using melee attacks to witness how everything that moves disappear in front of you (even behind the wall)
   5 . Just a reminder -> re-cast Lull (press 2) and Desolate Hands (press 3) to maintain low Restraint (circle in lower right corner)

Be advised Arcane [Fury] will help since it gives more damage output but Arcane Strike or any Attack Speed mod will not since more speed and less damage translates to building up Restraint faster resulting in being unable to cast Serene Storm
