willow should be able to burn her hair with a torch/lighter and this way she can equip a helmet/hat and tool/weapon at night. it could be limited so her hair needs to regrow after you burn it few times xxxxxxD also could willow have overheat immunity. that means she doesnt need any cooling items in summer and maybe she could have some sort of warning when it starts smoldering around her in summer these perks would make her interisting for me and yeah fireimmunity sounds also
