The Stealthy Ninja! by omeganave

Have you ever wanted to be a ninja? Well now you can! Whenever you use an Invisibility Potion, players can see the item you're holding. Well not with this weapon! It's an air block in item form! You can kill any player / mob (except the Ender Dragon) in one hit! You move 10 times as fast! Mobs don't follow you! Your health is halved so that it's not TOO OP. And best of all... It's unbreakable! Enjoy!

I haven't tested it, so I'm not sure if it'll work. Try it for yourself, and tell me what happens!
