Much like the normal enderman, the mutant enderman is also normally neutral unless stared at. But the second you look away from its gaze, the mutant enderman pulls you in towards it and blinds you at the same time.
Also,the mutant enderman gets angry if it sees you wearing a pumpkin or sometimes just randomly; and if it's angry, it'll automatically attack you! Also, the mutant enderman has four arms when it is attacking you.
When the mutant enderman teleports, it emits its endersoul that produces a huge impact, knocking all mobs around it, while occasionally blinding them, and dealing 2 hearts of damage. The endersoul looks like a translucent pink Mutant Enderman that is somewhat bigger.When you get close to it the mutant enderman dose not attack.But if harmed could cause serious damge.
Of course, if its hands are all free, the mutant enderman can use its basic melee attack with one of its four arms. Beware, because although the mutant enderman's inner arms deal 4 hearts, its outer arms deal 5 hearts of damage.
Like regular endermen, they can pick up blocks. But instead of 1, they can pick up 2-4. They can also throw them at you causing 3-4 hearts of damage on a direct hit and 2 hearts of damage as splash damage.
The mutant enderman's clone attack spawns eight of the mutant enderman's endersoul minions to torment you. Along with that, the mutant enderman itself becomes disguised as one of them too, but it is a bit darker in color.
During this attack, the clones will randomly attack their target by dealing 0.5 hearts of melee damage, as well as teleporting randomly. Take note that in this form, the mutant enderman deals 3 hearts for each attack and heals 1 heart for each successful attack!
Hitting the real mutant enderman ends the clone move.
The mutant enderman doesn't just teleport itself. It teleports you too. Its telesmash, bends you through space and time into the air, hitting you with 3 hearts and dealing fall damage. Also you get nausea after traveling through space and time.
Although the mutant enderman still takes damage in rain, fighting it in rain will increase its tendacy to scream. Along with delivering the voice of Death himself, the mutant enderman's scream deals 2 hearts of armor-piercing damage from its impact, and stopping the rain if raining.
If you're lucky, you may individually avoid the scream's effects of major poisoning, lengthy weakness, crazy energy depletion (hunger), and troublesome nausea. However, if you're unlucky, this scream could kill you in seconds.
When you kill the mutant enderman, its soul becomes unstable and deteriorates. But when this happens, the mutant enderman shoots out endersoul fragments that can explode within a few seconds, blasting you around and dealing some damage.
However, now you can wear a pumpkin to prevent the impacts of the fragments and most of the damage. Luckily, you'll be rewarded with eight drops of ender pearls or eyes of ender. You can also use the fragments to make an Endersoul Hand.
Tips for Defeat Edit
Have diamond gear with Protection IV and Feather Falling IV. Have a lot of milk to get rid of the status effects. Put a pumpkin on right before he dies to avoid as much damage as possible.
