Multiattack

The vine lord makes two claw attacks and four tendril attacks. A single creature can't be the target of more than one tendril attack per turn.

Claw

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 8 (1d6 + 5) slashing damage.

Spore Sacs (1/week)

The vine lord can release seeds from specialized sacs on its tendrils. These seeds sprout into 1d4 green spore pods that reach maturity in 3 days. The pods contain noxious spores that are released when the pod is stepped on, picked, or otherwise tampered with. A humanoid or beast that inhales these spores must succeed on a DC 14 Constitution saving throw against disease or tendrils start growing inside the creature's body. If the disease is not cured within 3 months, the tendrils take over the creature's nervous system and the victim becomes a tendril puppet.

Tendril

Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 7 (1d4 + 5) slashing damage plus 3 (1d6) poison damage.

Awaken the Green (1/Day)

The vine lord magically animates one or two trees it can see within 60 feet of it. These trees have the same statistics as a treant, except they have Intelligence and Charisma scores of 1, they can't speak, and they have only the Slam action option. An animated tree acts as an ally of the vine lord. The tree remains animate for 1 day or until it dies; until the vine lord dies or is more than 120 feet from the tree; or until the vine lord takes a bonus action to turn it back into an inanimate tree. The tree then takes root if possible.
