Tendril

Melee Weapon Attack: +4 to hit, reach 10 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage plus 2 (1d4) acid damage, and the target is grappled (escape DC 12). Until this grapple ends, the target is restrained and takes 2 (1d4) acid damage at the start of each of its turns. The violet has two tendrils strong enough to grapple creatures; each can grapple only one target. If the acid damage reduces the target to 0 hp, the violet regains 7 (2d6) hp.
