Spellbinder

The Spellbinder (エグザミネイション) is a Keychain for Sora's Keyblade which appears in Kingdom Hearts and Kingdom Hearts: Chain of Memories.

In Kingdom Hearts, after obtaining each of the seven spells, Sora brags that his magic is as good as Donald's, and Goofy suggests that he talk to Merlin. Merlin rewards Sora's progress with the Spellbinder. In Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories, the Spellbinder is the signature Attack Card for 100 Acre Wood, but must be obtained as a reward before it will appear randomly. In Kingdom Hearts: Chain of Memories, Owl gives Sora the Spellbinder once he is found, and in Kingdom Hearts Re:Chain of Memories, it is found in a chest at Tigger's Playground.

Design
The Spellbinder Keyblade takes its theme from the imagery of magic and astrology. Its keychain is a rusty chain, with a spellbook as the token.
