Challenge 1
False Appearance. If the blight is motionless at the start of combat, it has advantage on its initiative roll. If a creature hasn't observed the blight move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the blight is animate.
Spider Climb. The blight can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Multiattack. The blight makes two Claw attacks.
Claw. Melee Weapon Attack: +4 to hit (with advantage if the target is missing any of its hit points), reach 10 ft., one target. Hit: 5 (1d6 + 2) slashing damage.
Life-Draining Vines (Recharge 5–6). Snaking vines erupt from the blight. Each creature within 10 feet of it must make a DC 12 Dexterity saving throw, taking 9 (2d8) slashing damage on failed save, or half as much damage on a successful one. If at least one of the creatures that failed this save isn't a Construct or an Undead, the blight regains 9 hit points.
