To craft the armor and sword you will need to drop diamond armor and sword with a stack of flint for each armor piece and sword. You will also need more flint for the actual armor to work. The Armor won't work until you are wearing all of the armor and have more flint in your inventory.
When you are wearing the full armor you will get Jump boost 5, Speed 5, Resistance and Fire Resistance 5.
The Sword does some cool effects. When you attack something with the sword you will steal its life.
