For a Halloween special, I added the creepy set!  First off, you need some spooky items to craft the gem.  With that, you can make the sword, which does 10 dmg, has decent durability, and has fire aspect II on crafting.  Or, with the gem, you can make the armor, which has decent durability, decent armor, is not enchant-able, but with a full set you receive fire resistance!
