Carnivorous Weed

Lightning Absorption. Whenever the carnivorous weed is subjected to lightning damage, it takes no damage and regains a number of hit points equal to the lightning damage dealt.

Legendary Resistance (3/Day): If the carnivorous weed were to fail a saving throw, it may choose to save instead.

Entangling Vines. The carnivorous weed can have up to six entangling vines at a time. Each entangling vine can be attacked (AC 20; 10 hit points; immunity to poison and psychic damage). Destroying a entangling vine deals no damage to the carnivorous weed, which can extrude a replacement entangling vine on its next turn. An entangling vine can also be broken if a creature takes an action and succeeds on a DC 15 Strength check against it.

Multiattack. The roper makes four attacks with its entangling vine, uses Reel, makes one attack with its piercing vine, and makes one attack with its bite.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 4) piercing damage.

Piercing Vine. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (1d12 + 4) piercing damage.

Entangling Vine. Melee Weapon Attack: +7 to hit, reach 50 ft., one creature. Hit: The target is grappled (escape DC 15). Until the grapple ends, the target is restrained and has disadvantage on Strength checks and Strength saving throws, and the carnivorous vine can't use the same tendril on another target.

Reel. The carnivorous weed pulls each creature grappled by it up to 40 feet straight toward it.
