Neutron Capture - a double dip added to your base damage of your gun w/ radiation element now.

Demon Core - the darts allow for more damage build up for Neutron Capture


Glow Up - crit chance for guns is really nice

Chain Reactor - applies to CHROMA Accelerator and inherits source meaning it builds up more damage for Neutron Capture


Confirmative Reality - ez cooldown

Decoherence - applies to CHROMA Accelerator and inherits source meaning it builds up more damage for Neutron Capture

Critical Funding - allows for more bullets to be fired during Neutron Capture without reloading


Make Extraordinary - allows for more crits on both guns and CHROMA Accelerator

Equipment

Weapons
Repkit & Ordnance
Utilities

Wombo Combo - the 8x damage boost applies to Neutron Capture making this basically the best gun for this build

Jakobs Pistol - any jakobs pistol will work. When you detonate CHROMA Accelerator you will shoot your pistol at the same time. The hand animation on the pistol will cancel the detonation and freeze it mid air. Allowing for Demon Core darts to hit more and build up more Neutron Capture. Discovered by Rapoulas on discord. This is not needed as it is a bug but it does a lot


War Paint - more fire rate means more bullets before Neutron Capture ends

Kill Spring - allows for better healing

Triple Bypass - can also be used to heal w/ repkit spam


Slippy = can be used to proc CQC

Jakobs Grenade Crit Knife - gives peak damage


Reactor or Purple Class Mod w/ points into Decoherence - builds up more Neutron CaptureGet Action Skill Duration if possible


Watts 4 Dinner - bonus element builds up more Neutron Capture


Hero of Bullet - allows for more DPS while Neutron Capture is active
