Spellcasting. The druid is a 4th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 12, +4 to hit with spell attacks). It has the following druid spells prepared:
Cantrips (at will): druidcraft, produce flame, shillelagh
1st level (4 slots): entangle, longstrider, speak with animals, thunderwave
2nd level (3 slots): animal messenger, barkskin
Quarterstaff. Melee Weapon Attack: +2 to hit (+4 to hit with shillelagh), reach 5 ft., one target. Hit: 3 (1d6) bludgeoning damage, 4 (1d8) bludgeoning damage if wielded with two hands, or 6 (1d8 + 2) bludgeoning damage with shillelagh.
False Appearance. While the blight remains motionless, it is indistinguishable from a tangle of vines.
Constrict. Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage, and a Large or smaller target is grappled (escape DC 12) . Until this grapple ends, the target is restrained, and the blight can’t constrict another target.
Entangling Plants (Recharge 5-6). Grasping roots and vines sprout in a 15-foot radius centered on the blight, withering away after 1 minute. For the duration, that area is difficult terrain for nonplant creatures. In addition, each creature of the blight’s choice in that area when the plants appear must succeed on a DC 12 Strength saving throw or become restrained. A creature can use its action to make a DC 12 Strength check, freeing it self or another entangled creature within reach on a success.
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 four attacks: two with its branches and two with its grasping roots, If it has a target grappled, the blight can also make a bite attack against the target as a bonus action.
Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 19 (3d8+6) piercing damage.
Branch. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit (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.
