When etched with this rune, a weapon's hilt or haft becomes engraved with grooves that match the imprints of a wolf's teeth. By putting a fanged weapon in your mouth, you can transform into an animal.

Interact (magical, polymorph, transmutation)
Effect You transform into a Small or Medium animal that wields the fanged weapon in its jaws; the animal matches the animal you are most closely associated with (a lizardfolk would turn into a lizard, a kitsune into a fox, a deer instinct barbarian into a deer, etc.) or a wolf if no specific animal is applicable. While in this form, you can attack with the fanged weapon even though you don't have any hands. However, you can attack only with the fanged weapon and you don't have hands or the ability to hold items. For effects dependent on how many hands you are using to hold the item, such as the two-hand trait, you are holding the weapon in two hands. You can Dismiss this effect, and it ends automatically if you drop the fanged weapon (whether or not of your own volition).

Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
