Just a Quick Armor-making Tip

So, I started a new Minecraft world yesterday for the 1.6 update. Already, I have full diamond armor, half with protection 4 enchant. How did I do it? Well, first you need diamonds. Once I had some basic iron stuff, I mined down to bedrock, and then I went 8 blocks above it. Once you are at this level, mine a huge, 2 block tall room. You will find diamonds for sure! As for the protection 4 armor, I simply enchanted a ton of books at level 1 enchants. I had about a 40% chance of getting protection enchants, it seemed. Then all I had to do was combine all the books in an anvil. And BOOM - then I had protection 4 diamond armor. Now, get crafting! :)
