Multiattack

The trumpetbloom makes three attacks: one with its stinger and two with its tendrils.

Stinger

Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 16 (2d12 + 3) piercing damage, and the target must succeed on a DC 15 Constitution saving throw or become poisoned for 1 minute. The target is paralyzed while poisoned in this way. It can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Tendril

Melee Weapon Attack: +6 to hit, reach 15 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage and the target is grappled (escape DC 14) if it is a Medium or smaller creature. The trumpetbloom has two tendrils, each of which can grapple only one target.
