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. 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.
