FOR [Rhino] or any frame with an iron skin or something like that.

i use this weapon since 1 months now with this exact build.
People who cross me ingame "Skull Company" know how it's efficient and crush everything even after hours of survival against anything.

• The HEAT is one of the most important component in this build because Nightwatch Napalm is the key.
• Galvanized Chamber will help to add damage

• Wildfire will add more heat + 1 shot into your mag (you will have 4 shots)

• You can replace Amalgam Serration by Serration if you want to add more damage.

• into your Sentinel add : all 4 Vigilante mods
  Doing this + [Vigilante Supplies] into your main weapons you will never need any ammunition ever.
  Doing this you will add 20% chance to get critical hit
  [Nightwatch Napalm] will crit too !!!

This is the best primary weapon for me into the game.
Using this build with a Rhino or any iron skin / shielded frame type will gives you enjoyment and fun and will put your DPS on the top of the list without any skills.

IF you add the Helminth skill : Eclipse on your [Rhino] you will get a DPS no one can match even Mirage herself.
ROAR + Eclipse + KUVA Ogris = Death to anything.

Work in perfect DUO with AKARIUS.

NOTE :

• This weapon is create to make FIRE BARRAGE (AOE Type) anything who will enter the AOE will burn. Enemies who are burning do not fire at you.
• This KUVA weapon is FIRE base (got it with Ember)
• The impact on the ground is very powerful and can push enemies into space (go fly away whoever you are)
• Accumulating impact + aoe fire will create a space where enemies can do absolutely nothing if the impact do not kill them the fire will do.
