It is dangerous to attack this enemy simply with your weapon, for it is dangerous at close range. It is easy to dodge its ranged attack (which consists of a boomerang throw), but you should restrain it before going in close. By grappling it with the Oraclos Chain, it will be unable to attack, so either charge the chain up and yank it out or run in and use your weapon.
Wings: White droplet or (?)
Shiny: Light stone
