As the great engineer Olivia once said: "In order to study the endermen, you have to become an enderman."
This mod allows you to do just that... well... kinda.
It adds two variants of enderman suits which are crafted with just one ingredient: ender pearls!
Now why go out of your way to obtain an expensive suit when carved pumpkins do the same thing? Because a), they add 0 defense and b), they obscure your vision quite a bit! The suits on the other hand, are as strong as diamond armor and allow you to see clearly with the only negatives being expense and smell (yes they smell like endermen). Plus the second variant makes you appear taller after jumping and doubles your reach.
Now as much as the suits prevent enderman from attacking you when looking straight at them, they will still twitch in discomfort as they still hate being looked at, and if you attack them... well... make sure you have a weapon on you as they will attack back nonstop.
