I just spent a good chunk of time placing a diamond sword into and out of an enchantment table to get a high level enchantment to come up as an option. I did that probably about two or three hundred times before I got a level 48 enchantment. How fun! It was Bane of Anthropods V with Fire Aspect II. Now, I consider Bane of Anthropods is fairly useless overall ...how many spiders are there in the game? But it can still be used as a regular sword with the occasional bonus when you happen upon a spider. Fair enough since we're meant to gamble with our hard earned XP. Wait... We're meant to gamble with our hard earned XP?!? ... And then there's Fire Aspect... Well, while the effect seems really cool, I've discovered that it should actually be called "XP Reduction". Why? When a monster dies from fire it drops no XP orbs. This enchantment is actually a negative effect... a curse. Using it means you get less XP because some of the monsters you hit with it are going to die from the fire. After doing a facepalm and shaking my head, feeling like I just wasted hours of collecting XP, I went to the walkway outside of my tower and I threw the sword into the lava. The way enchanting is set up is really bogus and not fun at all.
