though not design for singleplayer, did really want to test out how that would work - still keep to minimum format of 1 visitor and 3 player characters, just juggle between sheets rather than sit down with friends.
turn order need tweak, and player would have to assign visitor's stats during checks to actually keep mystery, but actually this was really fun overall! character stats and proficiencies naturally blossom into different little personality archetypes, so manage to come up with fun character interactions even without another player to bump heads with.
this is fun one to play solo if just want to kill some time fun faerie chase. :)
