Young Shadow Dragon

Evil. The dragon radiates an Evil aura.

Incorporeal Movement. The dragon can move through other creatures and objects. It takes 11 (2d10) force damage if it ends its turn inside an object.

Essence Link. The essence dragon is spiritually linked to a specific area or landmark. The dragon gains no benefit from a long rest when more than 1 mile away from its linked area. If the dragon dies, the area it is linked to loses its vital essence until it forms a new essence dragon, which can take centuries. When a creature first enters an area that has lost its vital essence in this way, they gain a level of fatigue and a level of strife. This fatigue and strife can be removed only by completing a long rest outside the area.

Innate Spellcasting. The dragons spellcasting ability is Charisma (save DC 16). It can innately cast the following spells, requiring no material components. 3/day each:darkness, detect evil and good

Multiattack. The dragon attacks once with its bite and twice with its claws.

Bite. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 20 (3d10 + 4) piercing damage plus 4 (1d8) necrotic damage.

Claws. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 17 (3d8 + 4) slashing damage.

Anguished Breath (Recharge 5-6). The dragon exhales a shadowy maelstrom of anguish in a 30-foot cone. Each creature in that area makes a DC 16 Wisdom saving throw taking 40 (9d8) necrotic damage on a failed save or half damage on a success.
