Endermen spawn on the player's Private Island in dark areas, although rarely. They can also be spawned by Enderman Minions on the player's island.
Endermen can also be spawned faster on a player's Private Island by using an End Biome Stick. This will make the island only able to spawn Endermen. They will be level 1-15 instead of 42 - 50 when spawned on private islands.
Endermen can be found in The End at levels 42, 45 and 50.
Behavior[]
Endermen in SkyBlock act almost exactly like Endermen in vanilla Minecraft. They are passive when spawned, and will not attack the player, instead choosing to walk around the area they spawned into randomly. If the player attacks them or looks directly at their head, they will become aggressive, chasing the player around until they touch water, despawn, or die. In SkyBlock, Endermen can also become agitated when throwing an Ender Pearl, but not a Silent Pearl.
Wearing a Pumpkin or Enderman Mask will prevent angering Endermen by looking at them.
Similar to in vanilla Minecraft, Endermen are immune to bows. If hit with an arrow, they won't take damage. Several bows are still able to deal damage to them, most notably the Juju Shortbow and Terminator.
When an Enderman takes damage from water, the damage number is blue.
When an Enderman is damaged by the Witch Mask, they will not become aggravated. This may be a bug.
