Double-Keychains
Of course, all sorts of random civilians in Kingdom Hearts have keychains to bestow upon their local keyblade master in exchange for his good deeds. Roxas has taken up a collection, presented below.
Kingdom Key
The Keyblade of Light chose Sora, and has always been at Roxas's call.
[Stats] Atk 3, Mag 1
[Ability] Defender (defense up when critical)
[Description] A plain key of average length with a silver blade, the teeth shaped vaguely like a crown. The hilt is wrapped in black and the boxy frame is yellow. Its keychain is shaped like the mouse silhouette that symbolizes the Disney Kingdom.
[Special Notes] The Kingdom Key cannot be used as a double keychain.
Traveler's Charm
At the end of the Mysterious Tower, Stiltzkin gives this keychain to Roxas -- for free, even.
[Stats] Atk 4, Mag 0
[Ability] Draw (draws in nearby enemy drops on the field)
[Description] Both keyblades are decorated with a sweeping arched hilt, tiger-print like Stiltzkin's bandana. The main-hand keyblade is long, and its teeth are red laced with black, sharp and shaped like a moogle's wings. The offhand keyblade is short, featuring a blunt head, almost like a hammer. The keychain, on the long blade, is shaped like a moogle's pom.
Fading Flower
Belle gives this keychain to Roxas after they fight the Shadow Stalker that had been set to haunt the ballroom by Xaldin.
[Stats] Atk 1, Mag 3
[Ability] Combo Up (longer combos increase damage for the finisher)
[Description] Both blades of this keychain are average-length. The mainhand hilt is delicately-curved, with guards like rose petals. A thick band winds up, sweeping out to one side at the tip, like a twisted petal. The offhand blade has a seemingly glass hilt with the guard twisted in vines. They grow over the length of the blade, surrounded by small blunt thorns, and the teeth are a cluster of particularly vicious spikes. On the mainhand, the keychain is a small blue-framed mirror.
