1.14 / 1.15 Enderman Farm
The Enderman Farm is one of, if not the best, end-game XP farm. When compared to the Guardian Farm, although Enderman drop less XP than Guardians, Endermen spawn in greater numbers which overall results in the player gaining more XP in a shorter amount of time; 30 XP levels can be achieved in as little as 3 or 4 minutes.
Currently, there are 2 Enderman Farms on the server, the original that was built within the first month of The End opening and the newest one. Both get equal amount of attention however the difference between the two is that the newest one incorporates a drop system to lower the Endermen's health allowing for easier and faster killing.
