Ambhibious. The dragon can breathe air and water.

Living Shadow. While in dim light or darkness, the dragon has resistance to damage that isn’t force, psychic, or radiant.

Shadow Stealth. While in dim light or darkness, the dragon can take the Hide action as a bonus action.

Sunlight Sensitivity. While in sunlight, the dragon has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Actions

Multiattack. The dragon makes two bite attacks.

Bite. Melee Weapon Attack: +6 to hit, reach 5ft., one target. Hit 7 (1d10 + 2) piercing damage plus 3 (1d6) necrotic damage.

Shadow Breath (Recharge 5-6). The dragon exhales noxious gas in a 1 5-foot cone. Each creature in that area must make a DC 1 3 Constitution saving throw, taking 21 (6d6) 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, and an undead shadow rises from its corpse and acts immediately after the dragon in the initiative count. The shadow is not under the dragon’s control and will attempt to flee.
