Aviana is the third boss in Zelda's Adventure. She is the Shrine Keeper of the Shrine of Air.
Aviana attacks by dive bombing Zelda and throwing her feathers at the princess. Her attacks will deal one Heart and half a Heart-worth of damage, respectively. Her only weakness, and the only attack she is vulnerable to, is the Feather Spell. The Spell can only damage Aviana when the Feather is shot at her wings; attacking her anywhere else will cause the attack to fail.
Aviana is fought a second time in the Vision Henge when Ganon summons the Shrine Keepers to fight Zelda again on her way to the final showdown. She is fought in the same manner as before, only now she is weaker.
