Keyblade
The Keyblade is the main weapon used by the player in Kingdom Hearts Unchained χ.
Each Keyblade starts off with 3 Medal Slots which serve to add different types of Medals on them to make them stronger and use different types of attacks and skills, after upgrading a Keyblade to a certain level, new Medal Slots will be unlocked on the Keyblade, up to a maximum of 5.
When upgrading a Keyblade, Medal Slots will feature Attribute Boosts, which give damage increases to specific types of Medals. Each Keyblade also has a hidden modifier to the strength of the Friend Medal equipped to it, regardless of attribute.
In the game you can gain materials to upgrade Keyblades, as well as change their appearance and increase the quantity of Medal Slots.
While Medals grant the overall strength of a Keyblade, if players equip Medals that exceed the overall Medal Cost, they won't be able to use the Keyblade until switching to a Medal with lower Cost.
When a Keyblade is used without Medals, the player uses Stock Medals as placeholders.
