Used with [Gauss] there are a few options to change to get more effective damage. Namely adding status duration can buff the damage your nuke will do if you replace [Serration], but you will be fine without. The gun is mainly used to break eximus overguard so your nuke can work correctly on them.

There are other better options for weapons, but none that work quite as nicely with the nuke due too the huge amount of heat being dumped on enemies. Being able to expedite suffering all of that can kill enemies very easily. Due too the nature of thermal sunder and the gun itself, unfortunately banes aren't really a choice, with no crits to dip into its a pretty hard loss.
