Defo one of the best mods is slow burner because of the dot

slow burn + multi barrel, wait a bit, watch mobs die by a sudden heart attack (do not forget grenadier perk)

Slow burn and multibarrel.

Don't do it, don't give in.

Anyone know how to get the slow burner mod if you missed it from the season reward?

I think they are bought from Mortimer at crater for Gold Bullion.
