Traits

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 20 feet of the dragon must succeed on a DC 21 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

Bite

+14 to hit, reach 10 ft (3 m). Hit: 2d10+8 plus 2d6 fire damage.

Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 19 (2d10+8) piercing damage plus 7 (2d6) fire damage.

Claw

+14 to hit, reach 5 ft (1.5 m). Hit: 2d6+8 slashing damage.

Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 15 (2d6+8) slashing damage.

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 19 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.

Fire Breath

Recharge 5–6

The dragon exhales fire in a 60-foot cone. Each creature in that area must make a DC 21 DEX save, taking 63 (18d6) fire damage on a failed save, or half as much damage on a successful one.

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 19 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.

Multiattack

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

Tail

+14 to hit, reach 15 ft (4.6 m). Hit: 2d8+8 bludgeoning damage.

Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 17 (2d8+8) bludgeoning damage.

Wing Attack (Costs 2 Actions)

The dragon beats its wings. Each creature within 10 feet of the dragon must succeed on a DC 22 DEX save or take 15 (2d6+8) bludgeoning damage and be knocked prone. The dragon can then fly up to half its flying speed without provoking opportunity attacks.

Climbing Advantage: This creature can climb at 40 ft. It can use walls and ceilings for tactical positioning. Consider using 'Spider Climb' negation or fighting in open areas without vertical surfaces.
Fire Damage Mitigation: This creature deals fire damage. Advise players to have fire resistance ready or use water-based tactics. Consider environmental fire hazards that could backfire on the creature.
