Multiattack

The vine lord makes one Tendril attack and two Thorned Slam attacks.

Tendril

Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 7 (1d4 + 5) slashing damage plus 7 (2d6) poison damage, and the target must succeed on a DC 16 Constitution saving throw or become infected with a vine seed (see the Vine Seed trait).

Thorned Slam

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage plus 10 (4d4) piercing damage.

Forest Protectors (1/Day)

The vine lord magically calls 1d4 awakened trees or tendril puppets, or it calls 1 Plant with a challenge rating of 4 or lower. The called creatures arrive in 1d4 rounds, acting as allies of the vine lord and obeying its spoken commands. The Plants remain for 1 hour, until the vine lord dies, or until the vine lord dismisses them as a bonus action.
