Master Form

When you merge with both of your teammates to go into Master Form, your costume will change into a yellow outfit and gain the ability to use two Keyblades (you can select Master Form's Keyblade through Sora's equipment in the item menu). In Master Form, you'll have increased strength and magic, and can use magic to hold one of your Keyblades. Unfortunately, you can't have any one in your party until you go out, and your drive gauge goes down (If the drive gauge runs out when the number is on zero, you will automatically change back to Standard Form). Picking up one small Drive Orb gives your Master Form 1 EXP while picking up a big one gives 3 EXP, which is needed to level it up. You'll get this Form from King Mickey once you meet him in Hollow Bastion.
