False Appearance. While the blight remains motionless, it is indistinguishable from a dead tree.
Siege Monster. The blight deals double damage to objects and structures.
Multiattack. The blight makes one Branch attack and one Grasping Root attack.
Branch. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage.
Grasping Root. Melee Weapon Attack: +9 to hit, reach 15 ft., one creature not grappled by the blight. Hit: The target is grappled (escape DC 15). Until the grapple ends, the target takes 9 (1d6 + 6) bludgeoning damage at the start of each of its turns. The root has AC 15 and can be severed by dealing 6 slashing damage or more to it at once. Cutting the root doesn't hurt the blight, but ends the grapple.
