If you not mind grinding shards for thousand of years, boshe is really funny to play since bows + arrows have really good crit values when combined together
I originally tried to do a crit build with him, but sadly all bows that have good crit rates are the ones that don't have endgame vigor tied to them so despite doing crits on practically almost every turn (his crit rate was like around 90% iirc) he didn't have the vigor to go alongside it, planning to grind shards for him on my second playthrough since i want to use all the characters i used less or not at all in my first playthrough.
