DM: I don't believe saves are ability checks, unfortunately, so that wouldn't affect that. Yeah, it is its own circumstance.
Player: It's its own circumstance? In that case, I'm going to spend my point for Deadeye.
DM: Okay. Advantage on the shot.
Player: Advantage on the shot.
DM: Go for it.
Player: And do I want to go nuts? I'm going to go nuts. I'm going to add Sharpshooter to that, might as well.
