This sounds like a pretty good kit! It would be cool if it was added. Btw, the sword doesn't need Unbreaking, you can just put the sword away in your inventory for a second, and it will automatically repair itself :D
You should make a game where you start out with a weapon, then when you kill other players, you are able to get a better class, and whoever has the highest class at the end of the game wins! :D
