i building a winter witch and wanna use the nails as weapon combined with the demon claws.

now i need some feats so it have use, but i not really sure if nails are unarmed weapon or that demon claws are unarmed.
some help svp.

Demon claws (the mythic ability) counts as unarmed. A witch's nails count as natural weapons, so that means they too count as unarmed weapons.
