Celestial Forest Guardian

Woodland Magic. Golem can speak with plants and animals. They can teleport from one tree to another, luring interlopers away from their groves. If pressed, a Golem can beguile humanoids with her enchantments, turning enemies into friends. They also know a handful of useful spells.

Immutable Form. The golem is immune to any spell or effect that would alter its form.

Magic Resistance. The golem has advantage on saving throws against spells and other magical effects.

Magic Weapons. The golem's weapon attacks are magical.

Innate Spellcasting. The golem's innate spellcasting ability is Constitution (spell save DC 18). The golem can innately cast the following spells, requiring no material components:

At will: druidcraft

3/day each: entangle, goodberry

1/day each: barkskin, pass without trace, shillelagh

Multiattack. The golem makes two slam attacks.

Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.

Forest Charm. The golem targets one humanoid or beast that she can see within 30 feet of her. If the target can see the golem, it must succeed on a DC 14 Wisdom saving throw or be magically charmed. The charmed creature regards the golem as a trusted friend to be heeded and protected. Although the target isn't under the golem's control, it takes the golem's requests or actions in the most favorable way it can.

Each time the golem or its allies do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the golem dies, is on a different plane of existence from the target, or ends the effect as a bonus action. If a target's saving throw is successful, the target is immune to the golem's Forest Charm for the next 24 hours.

The golem can have no more than one humanoid and up to ten beasts charmed at a time.
