Bronze Shinryu

Angel's Sight. Magical darkness doesn't impede The Shinryu's darkvision. 

Magic Resistance. The Shinryu has advantage on saving throws against spells and other magical effects. 

Angelic Weapons. The Shinryu's weapon attacks are magical. 

Amphibious. The Shinryu can breathe air and water.

Innate Spellcasting. The Shinryu's innate spellcasting ability is Wisdom (+9 to hit with spell attacks). It can innately cast the following spells, requiring no material components:
At Will: Enhance Ability, Sending
3/day each: Cure Wounds, Aid, Daylight
1/day each: Death Ward, Mass Cure Wounds, Heal

Change Shape. The humanoid magically polymorphs into a shining, bronze dragonoid that is a size large or back into its true form. It reverts to its true form if it dies. The Shinryu chooses whether its equipment falls to the ground in its space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the DM decides whether it is practical for the new form to wear a piece of equipment, based on the creature’s shape and size. Its equipment doesn’t change size or shape to match the new form, and any equipment that the new form can’t wear must either fall to the ground or merge with it. Equipment that merges with the form has no effect until the Shinryu leaves the form.

Multiattack. The Shinryu makes two attacks: one with its shortbow and one with its claw.
