Spell Weaver is a Command Style exclusive to Aqua in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix. It is activated by using magic Deck Commands, such as Fire or Blizzard. It was known as Magic Wish in the Japanese release.
While using Spell Weaver, Aqua uses the power of light to hover the Keyblade in midair, allowing her to swiftly attack enemies while also enhancing her magic capabilities with her combo finisher being a short-range blast of light. It is activated after filling the Command Gauge with a variety of magic-based commands. The finisher consists of Aqua performing a magical spinning attack, controlled by the analog stick.
When Aqua is using Spell Weaver, she gains a white aura around her.
