What are the good Mutators?

[Ratguts]

I have heard twisting wounds is good same with something like bandit. I just want to know if those are worth upgrading early.

Also just want to hear what mutators others are using and with what guns.

[Vexillarius]

Fetid wounds, tainted blade, twisting rounds, supercharger, momentum, harmoniser. These are the go to ones i use. Some like supercharger i only use on deceit so it's super niche but if you use deceit you want it.

They're pretty much all good. You choose your mutator based on your weapon & build. The mutator should synergize.
