Ice Arrow

The Ice Arrow is the second of the three mystical weapons of Arturus. It is used to defeat the dragon robot boss in the fire planet in Astro-Knights Island. When you enter the dragons chamber you try to go behind his mace-tail without getting maced after that click the lever. The dragon is temporarily shut down. You notice that it's mouth opens. Fire the arrow into his mouth when he is temporarily shut down. (It needs perfect timing though.) Continue this two more times to defeat the dragon. Binky Bard will steal it from you later.
