Alburnum Cloak

This mass of thorny sticks and dead leaves is somehow bound into the vague shape of a cloak. When touched by a creature that is not attuned, the sticks ooze a deep red sap. Any blood shed by an attuned creature appears to have the same consistency.

Once per day, a creature attuned to the mantle can use a bonus action to fall under the effects of the primal beast variant of the guardian of nature spell.
