Yeah, PowerA Fusion Pro 2, imo the best choice by far if you can live with it being wired. Left paddles are set to dpad up and down, and right paddle (only have one installed) is mapped to B. Can't play games like this without it, so I end up packing it up in its case every day to use with both Series X and S. Only thing that bugs me is that I can only set the trigger locks to the middle setting. It doesn't register them at all if you set it to the shortest pull, but that's the game's fault not the gamepad.
Turtle pope gives the clue, but it's Brother Corhyn's quest. Solving the statue puzzle won't do any good if you haven't moved him along a few steps.
