The most fun [Catabolyst] build out there. High damage, crit and status, that also scales very well. The riven needs heat for the cascadia flare arcane. As a beam weapon you will have no issues keeping the arcane's buff up. Without a similar riven and the arcane simply use [Lethal Torrent], the gun still evaporates enemies. [Synth Charge] is here for the grenade to actually do damage an my oh my does it do it do wonders.

The only real downsides to this gun are:

• The lack of a vibration on your controller (personally I like to feel my guns work)

• The grenade not being auto thrown on an empty magazine

• If you aren't using primed sure footed another drawback is the potential knockback if you throw the grenade close to yourself.

• The high forma count to achieve perfection

But lets be honest if you have the weapon you've already gotten to a point in the game where these drawbacks are trivial or can be easily countered.
