Blue Stalfos (Sub-Boss)

Blue Stalfos (デスタルフォス, Death Stalfos) is the mini-boss of the Ancient Tomb, the eighth dungeon in Oracle of Ages. The only way to defeat it is for Link to use his sword to return the red round ball of energy it shoots out at him. If Link manages to strike him with the ball, he'll turn into a bat, allowing Link to damage him until he reverts to his true form. However if Link gets hit by the ball, he'll turn into a slow moving baby that can't use any of his weapons until he returns back to normal.

Blue Stalfos will also fire out asterisk shaped energy as well. These will only break and hurt Link if he tries to hit them with his sword.
