Having fortune is optional, but it's exceptionally helpful. In order to obtain xp, you're going to need a pickaxe. You just have to know what to bring, and where to go to quartz mine effectively.ġ. Thankfully, protecting yourself in the nether is very easy to do. The nether can be a dangerous place, especially for newer/unprepared players.
However, that involves a trip to the nether, and there's one big difference between mob farms and the nether (excluding productivity, of course), and that's the danger. I find that Quartz Mining is the most efficient way to obtain xp. XP can be obtained very quickly and efficiently even without farms. However, it's good that mob farms aren't the only way to get experience.
We all know that ever since the 1.8 update mob farms, especially enderman xp farms, have been very slow, almost non-functional.
