The pirate sword cannot be quick-crafted or taken from the creative inventory. If you craft it with a crafting table, it will have the Looting X enchant on it. Very useful when trying to collect ender pearls, which is normally very time consuming.

There is one block - the Rainbonium Ore. It is even more rare than diamond and spawns on level ten and under. It drops a Horrific Sword Handle when broken with at least an iron pickaxe.

There are additional items, like a teleportation staff, a food that gives strength III, and much more. Enjoy!
