Dire Bonesword: The magic in this sword comes from the anka feather with whose essence it's infused. Exceedingly rare, an anka is an immortally reincarnating bird much like a phoenix, only it is born of ice instead of fire; as such, its feathers can only be given by the creature itself, if they are stolen or fall off on their own, the melt to ordinary water.The feather was set into a large sword sculpted from the femur of a particularly nasty dire bear. Once a day, you can add 2d8 ice damage to a basic melee attack made with the sword, and while holding it+3 to checks involving nature, as long as they happen in nature.
Quirk: Pyrophobe. Is unnecessarily nervous about open flames.
