I had a silly thought with the playtest witch and swashbuckler. The thought was a swashbuckler taking witch multiclass and then taking living hair and fighting that way. You could also reverse this and have the Witch take swashbuckler multiclass and grab dizzying parry to make the hair get +1 more ac when using it to parry.
I know the multiclass feats for these classes dont exist in the playtest. But just following the pattern of level 4 you pick one class feat, and level 6 pick one class feat equal to half your level.
would apply runes to your hair be frosted tips?
or maybe getting those weird shapes shaved into the side of your head.
I think the runes would be put on with hair ties or bows. like you would put ruins on hand wraps. got to look your best after all and have you eye brow hair all neat with a bow.
