Aircalibur (エイルカリバー Eirukaribā, also known as Alacalibur in the game data of the English version of The Sacred Stones) is an Anima Magic tome appearing exclusively in Fire Emblem: The Binding Blade, and unused in Fire Emblem: The Sacred Stones. This tome is effective against Flying Units, as suggested by its description: "Tears through wings of flying units". While Aircalibur is not explicitly stated to be a Wind tome, the wind blades that manifests during its casting make it closely resemble one.
