Leafmingle

Whispering Wind. Leafmingle can mimic any sound it has heard, including voices. A creature that hears the sounds can tell they are imitations with a successful DC 15 Wisdom (Insight) check.

Regeneration. While in direct sunlight, Leafmingle regains 5 hit points at the start of its turn.

Nature's Camouflage. Leafmingle has advantage on Dexterity (Stealth) checks made to hide in forest terrain.

Fey Step. As a bonus action, Leafmingle can magically teleport up to 30 feet to an unoccupied space it can see that is also in direct contact with a tree.

Poison Mulch Explosion (On Death). When the Leafmingle dies, its body rapidly decomposes, releasing a burst of poisonous mulch. All creatures within 10 feet of the Leafmingle must make a DC 15 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one.

Multiattack. Leafmingle makes two attacks: one with its Leafy Grasp and one with its Entangling Vines. If entangling vines is on cooldown, both are made with the Grasp.

Leafy Grasp. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 8 (1d10 + 3) bludgeoning damage.

Entangling Vines (Recharge 5-6). Leafmingle releases vines in a 15-foot radius centered on itself. The vines turn the ground in the area into difficult terrain. Each creature in the area when the vines appear must succeed on a DC 14 Strength saving throw or be restrained by the entangling vines. A creature restrained by the vines can use its action to make a DC 14 Strength check, freeing itself on a success.
