I honestly think everybody's got this weapon wrong. Everybody runs it on SKL/BLT BL 120+ builds with Evelyn in the left hand or silly things like Rosmarinus or whatever. I don't think that makes sense at all. The name of this game is parry baiting + viscerals, right? Everything else is basically context. So, people will whiff R1s at each other until somebody can get a parry in, visceral and end it. Sometime you'll stagger somebody who's dashing and get a few R1s in unpunished. More advanced (and successful) builds have some form of ranged attack that they can use to put pressure on the opponent and force him to come close and try to R1, at which point they'll try to parry and punish it. This is the case with the HMLS or with arcane tools like Executioner's Glove, or with Bloodtinge builds with stuff like Evelyn + Chikage... who won't visceral you btw, most probably just burst you to death, mostly because parrying with an Evelyn is that much more of a commitment compared to parrying with a Blunderbuss (if you whiff you most likely miss too, and get punisher; with Blunderbuss a lot of times you'll whiff the parry but still hit the guy, staggering him). Now, the Reiterpallasch requires minimal BLT, scales its damage on Physical DMG gems, requires only one hand to shoot. To me, this means the following: take your VIT and SKL to 50, END to whatever you feel like doing (most likely 20), BLT to 10, completely ignore everything else (STR, ARC); take the transformed Reiterpallasch in your right hand, Blunderbuss in your left, go invade. You'll be under BL 100 (most likely 93-94), essentially do the same visceral damage as the BL 120 guys and have exactly as much HP as they do, you can bait the parries with a high damage pistol shot from a range and then parry people who get in range with an actual Blunderbuss to do a visceral like any pure SKL (or "Quality" SKL) build with minimal investment.
