The Battered Root-Tankard of Oakhaven

This vessel appears as a battered and stained tankard woven from living ash-tree roots and petrified briars. It is caked in dark, damp soil and stained with deep purple juices that never seem to dry. Small, pale mushrooms grow from the gaps in the weave, and the interior smells of wet earth and fermented berries. Despite its crude appearance, the wood is harder than iron and warm to the touch.
