Traits
Legendary Resistance (2/Day)
If the dragon fails a saving throw, it can choose to succeed instead.
Tunneler
The dragon can burrow through solid rock at half its burrowing speed and leaves a 15-foot-diameter tunnel in its wake.
Unusual Nature
The dragon doesn't require air.
Actions
Multiattack
The dragon makes one Bite attack and two Claw attacks.
Bite
Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 13 (2d6 + 6) piercing damage plus 3 (1d6) cold damage.
Claw
Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.
Tail
Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 13 (2d6 + 6) bludgeoning damage.
Cold Breath (Recharge 5–6)
The dragon exhales a blast of frost in a 60-foot cone. Each creature in the cone must make a DC 18 Constitution saving throw. On a failed save, the creature takes 36 (8d8) cold damage, and its speed is reduced to 0 until the end of its next turn. On a successful save, the creature takes half as much damage, and its speed isn't reduced.
Bonus actions
Phase (3/Day)
The dragon becomes partially incorporeal for as long as it maintains concentration on the effect (as if concentrating on a spell). While partially incorporeal, the dragon has resistance to bludgeoning, piercing, and slashing damage.
Legendary action uses: 2. The creature can use one option at the end of another creature’s turn and regains spent uses at the start of its turn.
Legendary actions
Tail Attack
The dragon makes one Tail attack.
Treacherous Ice
Magical ice covers the ground in a 20-foot radius centered on a point the dragon can see within 120 feet of itself. The ice, which is difficult terrain for all creatures except lunar dragons, lasts for 10 minutes or until the dragon uses this legendary action again.
Regional effects
The region containing an ancient or adult lunar dragon's lair is warped by the dragon's magic, which produces one or more of the following effects:
- Black Frost: A thin layer of black frost covers the ground, which kills all ordinary plants growing within 6 miles of the lair if the dragon is ancient, or within 3 miles if the dragon is an adult.
- Haunting Moan: A haunting sound gets louder or fainter (dragon's choice) the closer one gets to the lair. The moan is audible 6 miles from the lair if the dragon is ancient, or 3 miles if the dragon is an adult.
- Moon Devils: Swirling funnels of dust and frost known as moon devils crisscross the area within 1 mile of the lair, intercepting other creatures they encounter. A moon devil is a free-willed air elemental that deals cold damage instead of bludgeoning damage.
If the dragon dies, the moaning stops, the moon devils dissipate, and the black frost disappears over the course of 1d10 days, allowing plant life in the area to recover.
