Young River Dragon

Amphibious. The dragon can breathe air and water.

Flowing Grace. The dragon doesnt provoke opportunity attacks when it flies or swims out of an enemys reach.

Shimmering Scales. While in water, the dragon gains three-quarters cover from attacks made by creatures more than 30 feet away.

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.

Bite. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 19 (3d10 + 3) piercing damage.

Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) slashing damage.

Torrential Breath (Recharge 5-6). The dragon exhales water in a 30-foot-long 5-foot-wide line. Each creature in the area makes a DC 14 Dexterity saving throw taking 42 (12d6) bludgeoning damage on a failed save or half damage on a success.
