Adult Cave Dragon 2014
CR 19 dragon
Huge dragon, Neutral Evil
The cave dragon emits magical darkness in a 30-foot radius around it. The darkness moves with the dragon and spreads around corners. Darkvision can’t penetrate this darkness, and no natural light can illuminate it. If any of the darkness overlaps with an area of light created by a spell of 3rd level or lower, the spell creating the light is dispelled. At the start of each of its turns, the dragon chooses whether this aura is active. A successful dispel magic (DC 14) cast on the dragon suppresses this aura for 1 minute.
If the dragon fails a saving throw, it can choose to succeed instead.
The cave dragon can burrow through nonmagical unworked earth and stone. While doing so, the dragon can choose whether to leave the material it moves through undisturbed or leave a 10-foot diameter tunnel in its wake.
The dragon uses its spikes to hold itself in place while climbing, allowing it to climb difficult surfaces, including upside down on ceilings, without needing to make an ability check. If it climbs upside down on a ceiling or suspends itself on a vertical surface while leaving its claws free, it can’t use the Ruff Spikes reaction.
Actions
The dragon uses its Frightful Presence. It then makes one Bite attack and two Claw attacks.
Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 19 (2d10 + 8) piercing damage plus 10 (3d6) poison damage.
Melee Weapon Attack: +14 to hit, reach 5 ft., one target. Hit: 15 (2d6 + 8) slashing damage.

Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the dragon's Frightful Presence for the next 24 hours.
The dragon exhales a cone of black, poisonous gas in a 60-foot cone. Each target in that area must make a DC 21 Constitution saving throw. On a failure, a creature takes 56 (16d6) poison damage and is poisoned until it finishes a short rest. A creature can repeat the saving throw at the end of each hour, ending the effect on itself on a success.
Reactions
When a creature moves to a space within 5 feet of the cave dragon, the dragon flares its many feelers and spikes. The creature must succeed on a DC 21 Dexterity saving throw or take 9 (2d8) piercing damage and be prevented from entering that space.
