Beat the boat boss myself yesterday. Wasn't that hard with "Dark Souls training" but I kept making stupid mistakes and getting killed (almost had him on second attempt, but it must have taken a dozen attempts to finally beat him). Also I instinctively keep going for DS buttons still. Especially tricky is the Ki Pulse as RB is Attack in DS. I keep pressing X or Y and RB in the wrong order I know you could, sort of, remap the controls but I can't remap RB to X for example as then switching stances would be weird, if it would work at all. Plus the remapping works quite literally in this game, you remap a button to another button instead of defining a function and the on screen prompts don't update accordingly.
