Ramak's Wreath

Despite its charred appearance, small leaves sprout from the blackened branch and reach toward the sun. A parting gift from Archdruid Ramak, the ancient Treant Keeper of the Grove on Rainstar Isle. As his dying act, he breaks off his only remaining branch and imbues it with his essence, a fitting crown for the next Keeper of the Grove.
