Enderman/Skeleton Crossbreed

The Enderman/Skeleton crossbreed is one of the most incredibly dangerous standard enemy mobs in the game, added by Mob Fusion.

Fusion
They seem to mostly spawn in packs of 1-3 in snow biomes, and can also be physically merged with the two corresponding mobs.

In Combat
Enderman/Skeleton Crossbreeds are powerhouses. They are unimaginably strong. To defeat one, you will need about 1/2 rows of health and at least full iron armor. In battle, they will zip around constantly firing arrows at about double skeleton speed. They deal massive damage and require heavy hits to kill. They are hostile despite being endermen, and don't catch fire in the sun despite being skeleton. However, they will take damage in water/rain. Their only other weaknesses are high areas as they cannot curve their shots upwards and other crossbreeds. If cornered, and at a low level, the player should dig three blocks under them and cover the top. After doing so, he/she should heal up and dig out of the area. Running is dangerous as the skeleton can teleport in front of you and will always follow you.

Drops
Despite being hard to kill, they are worthwhile to fight as they drop enderman scales which can be crafted with two iron into reinforced ones, which make enderman scale armor-a VERY high tier armor. The scales are also used to spawn the Morbid Harvester.

Trivia
-It is debatable whether or not the "Mantis" is more lethal.

-They are the major reason living in snow biomes early on is not safe.
