Upgrading Armor and Weapons

Okay, we're adding this to the rules.

-Don't be STUPID with this, or we shall be forced to enact further limitations and that's not fun for anyone.
-Post your Upgrade in a separate topic from the initial item, but make sure to link to both topics in your Profile.
-USE THE TEMPLATE!!! Or you will see the business end of my flowery keyblade of death!
-Limitations must legitimately be a factor in play and/or combat. Don't think you'll get away with having a limitation that never affects your character, like slow feet on a flying character, or an inability to use Elements that a character doesn't use anyway.
-Have fun and be creative!
