This build is the first build I have ever made on the site, each mod is very important though some like [Serration] and [Wildfire] can be switch out for bane mods and other elemental dmg i used the type of damage because of its strong status and the way the riven mod is set up, now if you do not have a riven mod run [Thermite Rounds] instead of wild fire, run a bane mod (if you can) in the riven slot or run [Heavy Caliber] the results will still be worth it all they way through steel path
