Challenge 21 (33,000 XP)

Boil Over. When the red dragon hasn't unleashed its Fire Breath, the heat builds and rolls outward from it. While the dragon's Fire Breath is available, it emits immense heat, and each creature that starts its turn within 30 feet of the dragon must succeed on a DC 24 CON save or take 7 (2d6) fire damage. A creature that fails this save by 5 or more also suffers one level of exhaustion.

Legendary Resistance (3/Day). If the dragon fails a save, it can choose to succeed instead.

Actions

Multiattack. The dragon uses its Frightful Presence. It then makes one Bite attack and two Claw attacks.

Bite. Melee Weapon Attack: +17 to hit, reach 15 ft., one target. Hit: 21 (2d10+10) piercing damage plus 14 (4d6) fire damage.

Claw. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 17 (2d6+10) slashing damage.

Tail. Melee Weapon Attack: +17 to hit, reach 20 ft., one target. Hit: 19 (2d8+10) bludgeoning damage.

Frightful Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 21 WIS save or be frightened for 1 minute. A creature can repeat the save at the end of each of its turns, ending the effect on itself on a success. If a creature's save is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.

Fire Breath (Recharge 5-6). The dragon exhales fire in a 90-foot cone. Each creature in that area must make a DC 24 DEX save, taking 105 (30d6) fire damage on a failed save, or half as much damage on a successful one.

Legendary Actions

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. The dragon regains spent legendary actions at the start of its turn.

Detect. The dragon automatically detects every creature and trap within 30 feet of it, pinpointing the current location of each.

Tail Attack. The dragon makes a Tail attack.

Elemental Roar (Costs 2 Actions). The dragon roars at up to two creatures of its choice within 120 feet of it. Each target must succeed on a DC 21 CHA save or be vulnerable to fire damage until the end of its next turn. A target resistant to fire damage isn't resistant to it for the duration. A target immune to fire damage is still immune to it, even if the target fails the save.

Wing Attack (Costs 2 Actions). The dragon beats its wings. Each creature within 15 feet of the dragon must succeed on a DC 25 DEX save or take 17 (2d6+10) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed without provoking opportunity attacks.
