Candy Colossus

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

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

Summon Sugar Sprites. At the start of each of its turns, the colossus takes 10 (3d6) necrotic damage, and summons 3 sugar sprites (use the Sprite stat block). The colossus can have only 3 sugar sprites at a time. If the colossus is affected by a condition that would allow it to make a saving throw at the end of each of its turns to try and overcome the effect, it can pass the condition to one of its summoned sugar sprites.

Temptation of the Treat Titan. The colossus radiates a mesmerizing aura, compelling all hostile creatures within its vicinity to draw closer and partake of its body. At the start of each of its turns, a creature within 30 ft. of the colossus must succeed on a DC 17 Wisdom saving throw or use its reaction to move toward the colossus. If a creature ends this movement within 5 ft. of the colossus, they also take a bite out of its body, dealing 3 (1d6) piercing damage to the colossus and be affected by one of the following:

Brain Freeze. The creature takes 7 (2d6) psychic damage plus 7 (2d6) cold damage, and has its speed halved until the end of its next turn.

Caramel Coating. The creature's face and mouth are covered in caramel. Until the creature uses an action to clear the caramel away, it has the Blinded condition, and is unable to speak or cast spells that have a Verbal component.

Hot Chocolate Scald. Hot chocolate bursts from the colossus, and the creature must make a DC 17 Dexterity saving throw or take 14 (4d6) fire damage, and gain vulnerability to fire damage until the end of its next turn.

Regardless of which effect a creature takes, it also gains the effects of the Haste spell until the end of its next turn.

Glaze Guard. When a creature hits the colossus with a melee weapon attack, the attacker must succeed on a DC 12 Strength saving throw or have its weapon become lodged in the colossus' body. A creature can use its action to make a DC 12 Strength check to free the weapon - if the colossus has taken fire damage since the end of its last turn, the ability check automatically succeeds.

Multiattack. The colossus makes one Forked Fury and one Gelatinous Grasp attack.

Forked Fury. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 21 (3d10+5) piercing damage, and the target must succeed on a DC 17 Dexterity saving throw or have its speed reduced to 0 until the start of the colossus' next turn. If the target fails its saving throw by 5 or more, it also has the Restrained condition for the same duration.

Gelatinous Grasp. Melee Weapon Attack; +9 to hit, reach 5 ft., one target. Hit: 16 (2d10+5) bludgeoning damage, and the target must succeed on a DC 17 Dexterity saving throw or become coated in a layer of red gelatin. Initially, the gelatin has an AC of 10 and 10 hit points. At the end of an affected creature's turn, the gelatin swells and grows, gaining +2 to AC and an additional 5 hit points, and causes the affected creature's speed to be reduced by 15 ft. Should the gelatin reduce the creature's speed to 0, the creature is engulfed by the gelatin, and has the Paralyzed condition until the gelatin is destroyed.

Icy Infusion. When the colossus takes cold damage, it can make a DC 15 Constitution saving throw - on a success, it takes no cold damage, and instead gains temporary hit points equal to the cold damage it would have taken.

Blaze to Biscuit. When the colossus takes fire damage, it can make a DC 15 Dexterity saving throw - on a success, it absorbs the fire damage into a piece of dough, and then creates 3 sugar sprites (see "Summon Sugar Sprites").

The colossus 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 colossus regains spent legendary actions at the start of its turn.

Move. The colossus moves up to its speed.

Attack. The colossus makes one Forked Fury or Gelatinous Grasp attack.

Cane Catch (Costs 2 Actions). A giant candy cane appears from the colossus' abdomen. A creature within 20 ft. of the colossus must make on a DC 17 Dexterity saving throw. On a failure, the creature takes 9 (2d8) bludgeoning damage, and is pulled 15 ft. toward the colossus. If the creature fails its saving throw by 5 or more, it also has the Prone condition.

Jiggly Jelly Jam (Costs 2 Actions). The colossus chooses a point it can see within 30 ft. of it. All creatures within a 20 ft. radius of that point must succeed on a DC 17 Dexterity saving throw or take 13 (3d8) acid damage and be covered in red gelatin (as per it's Gelatinous Grasp attack). On a success, a creature takes half as much damage only. The affected area then becomes Difficult Terrain.
