Chocolate Golem

Cold Absorption. Whenever the golem is subjected to cold damage, it takes no damage and its Armor Class becomes 16 for 1 minute or until it takes fire damage. 

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.

Molten Body. When the golem takes 10 or more fire damage from a single source, all creatures within 5 feet take 3 (1d6) fire damage for every 10 fire damage the golem has received. For example, an attack that deals 40 fire damage to the golem will cause all creatures within 5 ft. of the golem to take 14 (4d6) fire damage. Any creature that would be subject to damage as a result of this trait can attempt a DC 16 Dexterity saving throw, taking half as much damage on a success.

Multiattack. The creature makes two slam attacks.

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 4) bludgeoning damage.

Molten Breath (Recharge 5-6). The golem exhales molten chocolate in a 10-foot cone. Each creature in that area must make a DC 16 Dexterity saving throw, taking 14 (4d6) fire damage on a failed save, or half as much damage on a successful one. A creature that fails its save is coated in chocolate, blinded, and restrained until the end of the chocolate golem’s next turn. If a creature covered in chocolate takes cold damage before the end of the golem’s next turn, the chocolate hardens and that creature is blinded, restrained, and incapacitated until the chocolate coating is destroyed. The chocolate coating has an AC of 10 and 5 hit points.
