i'd like to make a kitsune vigilante stalker who will wear sleeves of garments to constantly blend in to new environments. He'll have realistic likeness and probably weapon finesse but beyond that I'm not sure where to take things. any ideas or recommendations?
Serial Killer is good if he isn't, otherwise Taisetsu is solid for things like disappearing. If you do go with evil, worshipping Norgorber and taking his divine fighting style feat twice lets you make stealth checks to count one person per turn as unaware of your presence for your abilities.
You might want some of Batman style abilities- take somebody down, stash the body, and take their place.
