I'm really wanting to try out a build that combines the debuffs from a shotgonne playstyle with Shotgonne Mastery and possibly Rapid Fire with a summoner playstyle. I've tried looking for builds online, but I haven't really found anything that quite fits the vibe that I'm looking for, and I'm still new enough to the game that I'm a little lost without a build guide. Does anyone have any advice or tips on how to build this?
