Awakened Forest

False Appearance. While the trees remain motionless, they are indistinguishable from a normal forest.

Swarm. The forest can occupy another creature's space and vice versa, and the forest can move through any opening large enough for a Huge tree. The forest can't regain hit points or gain temporary hit points.

Multiattack. The forest makes two slam attacks. It can't make both attacks against the same target.

Slam. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 28 (6d6 + 4) bludgeoning damage, or 14 (3d6 + 4) bludgeoning damage if the forest has half of its hit points or fewer.

Entangling Vines. The forest can animate normal vines and roots on the ground in a 15-foot square within 30 feet of it. These plants turn the ground in that area into difficult terrain. A creature in that area when the effect begins must succeed on a DC 13 Strength saving throw or be restrained by entangling vines and roots. A creature restrained by the plants can use its action to make a DC 13 Strength (Athletics) check, freeing itself on a successful check. The effect ends after 1 minute or when the forest dies or uses Entangling Vines again.

The forest can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The forest regains spent legendary actions at the start of its turn.

Detect. The forest makes a Wisdom (Perception) check.

Slam Attack. The forest makes a slam attack.
