Draining Vines. Melee Weapon Attack: +4 to hit, reach 15 ft., one creature. Hit: 9 (2d6 + 2) necrotic damage, and the target's Strength score is reduced by 1d4. The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.

If a non-evil humanoid dies from this attack, a new Undead Flower rises from the corpse 1d4 hours later.

Nutritious Soil. The Undead Flower may plant its roots in loose soil, reducing its movement speed to 0. While planted, it regains 2d4+2 HP at the start of each turn.
