Tunneler. The cave dragon can burrow through solid rock at half its burrowing speed and leaves a 10-foot wide, 5-foot high tunnel in its wake.

Innate Spellcasting The dragon’s innate spellcasting ability is Charisma (spell save DC 15). It can innately cast the following spells, requiring no material components:

1/day each: Blur, Counterspell, Web

3/day: Darkness

Actions

Multiattack. The dragon makes three attacks; one with its bite and two with its claws.

Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) piercing damage plus 3 (1d6) poison damage.

Claw. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) slashing damage.

Poison Breath (Recharge 5-6). The dragon exhales a cone of black poison gas in a 30-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 45 (13d6) poison damage on a failed save and becoming Poisoned if it is a creature. The poisoned condition lasts until the target takes a long or short rest or removes the condition with Lesser Restoration or comparable magic. If the save is successful, the target takes half damage and is not poisoned.

Reactions

Ruff Spikes. When a creature tries to enter a space adjacent to a cave dragon, the dragon flares its many feelers and spikes. The creature cannot enter a space adjacent to the dragon unless it makes a successful DC 16 Dexterity saving throw. If the saving throw fails, the creature can keep moving but only into spaces that aren’t within 5 feet of the dragon and takes 4 (1d8) piercing damage from spikes.
