At the pinnacle of the Sky Castle, you will face Tiamat, the Fiend of Air. Tiamat is a multi-headed dragon with devastating breath attacks that can hit your entire party. She is vulnerable to BANE (Death) spells, though these have a low success rate. Focus your strongest physical attacks and offensive magic. Your White Mage should be constantly healing with CUR4 or CUR3, as Tiamat's attacks can quickly deplete your party's HP. Equip any defensive gear that reduces elemental damage. After a grueling battle, Tiamat will fall, and the Air Crystal will be restored. With all four crystals shining brightly, your final challenge awaits!
