Awakened Rotroot

False Appearance. While the tree remains motionless, it is indistinguishable from a normal tree.

Rotroot Sap. When the tree is hit with a melee attack, all creatures within 5 ft. are sprayed with acidic sap, taking (1d4) acid damage.

Magical Erosion. Prolonged exposure to this plant or any resources harvested from it will wear away at any permanent magical enchantment. For every four hours spent in proximity to the plant, an enchanted item takes on a minor detrimental effect. If it is placed within a bag of holding, handy haversack, or similar extradimensional space, the container holding the item suffers this effect.

Slam. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 14 (3d6 + 4) bludgeoning damage.

Sappy Flesh. When the tree is hit with a melee attack, it can choose to capture the weapon used to do it harm. The attacker must make a DC 15 Strength check or be disarmed as the weapon is lodged in roiling sap and twisting bark. The weapon can be retrieved if a creature takes an action to wrench it free with a DC 15 Strength check or if the tree takes an action to relinquish it.
