SPECIAL TRAITS

• Legendary Resistance (3/Day). If the dragon fails a saving throw, it can choose to succeed instead.
• Traumatic Brain Injury. The dragon’s Intelligence has been reduced to 5 as a result of brain damage, and it has lost its languages and spells.
• Grave Endurance. The dragon has advantage on saving throws against being charmed, and magic can’t put the dragon to sleep. It is also immune any type of disease.
• Inexorable Attacks. The dragon’s attacks are considered magical and can hit creatures on the Ethereal Plane.
• Ethereal Sight. The dragon can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.

ACTIONS

• Multiattack. The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.
• Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 7) piercing damage.
• Claw. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.
• Tail. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 16 (2d8 + 7) 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 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.
• Decaying Breath (Recharge 5-6). The dragon exhales shadow in a 90- foot line that is 5 feet wide. Each creature in that line must make a DC 19 Dexterity saving throw, taking 66 (12d10) necrotic damage on a failed save, or half as much damage on a successful one. A humanoid reduced to 0 hit points by this damage dies. This attack is considered radiant damage when used against undead creatures.

LEGENDARY ACTIONS

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option 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 makes a Wisdom (Perception) check.
• Tail Attack. The dragon makes a tail attack.
• Sepulchral Crush (Costs 2 Actions). The dragon uses its body to entomb a foe. Each creature within 10 feet of the dragon must succeed on a DC 20 Constitution saving throw or take 14 (2d6 + 7) bludgeoning damage and be forced prone. If the save failed by 5 or more the target is paralysed. A parlayed target may repeat the saving throw at the end of its turn but if it fails by 5 or more again it is petrified.
