Homebrew Enderman Species Details

Endermen seem particularly drawn to the End, where they gather in large groups. They are uncommon visitors to other dimensions, although they appear more often in pairs in such peculiar places as the warped forests of the Nether. They shun sunlight and are hurt by water, including rain. When an Enderman becomes the target of a ranged weapon or takes damage, it teleports to a safer location nearby and makes a distinctive “voop” sound at its destination.

Endermen have no known predators. When a Humanoid looks directly at an Enderman, the Enderman becomes enraged, opens its mouth horrifyingly wide, and rushes to attack with its long arms. Endermen are seen as wild and alien despite their humanoid form and are usually classed as monsters because of this. As a result, many avoid other humanoids, but certain groups of endermen are known to be social, and are quick to learn other languages. Once they can properly communicate with another being, it isn’t seen as so alien anymore. 

Enderman Traits

Evasive Teleportation. Whenever it takes damage or is the target of a ranged attack, the Enderman can teleport, along with any equipment it is wearing or carrying, to an unoccupied space it can see within 20 feet of itself (no action required). If this effect is triggered by a ranged attack, the Enderman teleports just before the attack hits, causing the attack to miss it. This trait is suppressed while the Enderman has the incapacitated condition.
