Bard Golem

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.

Hole-y Body.  Due to the holes in its body any wind based attacks do no damage to the Bard Golem and give it advantage on it's next action.

Stone's Song. Since the Bard Golem is born of magic the holes in it's body can be used to play a variety of songs causing different effects on all who hear them. Creatures affected by the songs will be able to reroll their saves at the top of their turn.

Alluring Sound.  The Bard Golem spends it's days roaming the world. Everyone who hears the song of the Bard Golem must make a DC 22 charisma save or be drawn inexplicably to the Bard Golem

Charmer of Nature. Nature is drawn to the pleasant songs of the Bard Golem and a group of small animals from the current biome nearly always reside with the Bard Golem

Multiattack. The golem makes two slam attacks.

Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 19 (4d8 + 6) bludgeoning damage.

Slow Song (Recharge 5–6). The golem targets one or more creatures it can see within 10 feet of it. Each target must make a DC 17 Wisdom saving throw against this magic. On a failed save, a target can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the target can take either an action or a bonus action on its turn, not both. These effects last for 1 minute. A target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
