Minecraft: Maximum Yield Automated XP / Blaze farm TUTORIAL!
In response to the demand I made my first tutorial, completely legit while on HARD difficulty. Yes, I died a few times...
This design is based around a Blaze spawner as they give the highest XP per kill bar ender dragons. Water was never an option in the Nether for me as I was convinced it would be a short lived unintentional side effect to Silk Touch.
