Molten Cores

Hate having to bridge in the nether? Then the molten core would be perfect for you. You would craft this with 4 magma cream in the corners, a nether star in the center, and blaze powder everywhere else. Once you have crafted this, you would hold down right click on it(like a bow), a custom sound would play, and you would be able to walk on lava for five minutes. The core would have a cooldown of 10 minutes, and would only be able to be used 10 times.
