Candles. The colossus has 7 candles on its head. If the candles are blown out or smothered, the colossus loses its Regeneration trait until it can relight them. A creature can extinguish 1d4+3 of the candles as an action, but must be able to reach them either by climbing the construct of by flying to them.
Magic Resistance. The colossus has advantage on saving throw against spells and magical effects.
Magic Weapons. The colossus' weapon attacks are magical.
Regeneration. The cake colossus regains 10 hit points at the start of its turn if it has at least 1 hit point.
Multiattack. The cake colossus makes three melee attacks: one with each of its two fists and one stomp attack.
Frosted Fist. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 20 (3d8+6) bludgeoning damage. Then, if the creature is Medium or smaller in size, it becomes stuck to the colossus' fist and is restrained (escape DC 17). The colossus can restrain up to one creature on each of its two fists. Creatures stuck to the colossus' fists take damage whenever the colossus makes an attack with that fist as if they were hit by it.
Stomp. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 39 (4d10+6) bludgeoning damage. The creature must make a DC 17 Strength saving throw or be knocked prone.
Cake Storm (Recharges After a Short or Long Rest). The colossus roars and causes magical frosting and cake chunks to descend from the sky in a 20-foot tall, 40-foot radius cylinder centered on a point the colossus chooses within 150 feet of itself. This has the same effect as a sleet storm spell with s spell save of DC 17 and dies not require the colossus' concentration. The effect does not douse the colossus' candles.
