Curse of Strahd
At the south end of the hilltop is a sickly copse, a grove of dead trees and shrubs with a huge, misshapen tree at its core. Blood oozes like sap from its twisted trunk. Embedded in the tree is a shiny battleaxe, beneath which lies a humanoid skeleton. The Gulthias tree creates blights from ordinary plants and is the only tree of its kind in Barovia.
The dead adventurer’s tattered leather armor isn’t salvageable, but the axe embedded in the tree is a magic battleaxe. Its handle is carved with leaves and vines, and the weapon weighs half as much as a normal battleaxe. When the axe hits a plant, whether an ordinary plant or a plant creature, the target takes an extra 1d8 slashing damage. When a creature of non-good alignment wields the axe, it sprouts thorns whenever its wielder makes an attack with it. These thorns prick the wielder for 1 piercing damage after the attack is made, and this damage is considered magical.
