Air Orb Is a summon stone, obtained by getting the ingredients Aldor requests you to get and bringing them back to him. After doing so, he will give you the Air Orb, which can summon the Air Wizard. (when in the right location)
The Air Orb, Summons the Air Wizard on top of the mountain in the Icy Village. After doing so, it has no other uses, and says: "I don't think this is the right place...", In the same way it did when trying to use it when not on top of Ice Mountain.
