The Desert Protecter

General
The Desert Protector is an Iron Golem-style Boss mob. It has 600 health, and is a part of the Post-Ender Dragon concept.

Appearence
The Desert Protector is an Iron Golem that has two heads. It looks similar to the predicted "Mob E". The Golem appears to be made of sandstone. To summon the Desert Protector, a player must drop a Desert Totem into a desert well. In desert wells, a chest will spawn having between 4 and 20 Totems. The totem's texture looks like a miniscule version of the Desert Protector.

Attacks
Upon summoning him, he will spawn in the desert well and will destroy the roof and will walk towards the player. It is faster than an Iron Golem but he is still a bit slow. His speed is not affected by Dark Blocks, giving the player an advantage over him. He has a melee attack, similar to an Iron Golem, that does 4 hearts of damage. He also has a ranged attack. He picks up a bit of sand off the ground (Not a block, he just picks up some sand) and throws it at thge player. This deals 2 hearts of damage. Once he is at half health (300) he enters his second phase. He walks even faster than before, like if a normal player was walking on any block except Dark Blocks. He does his ranged attack more often than before, which does 1 and a half hearts of damage. This makes instant healing potions necessary. Upon being defeated, he drops a new set of armor: Desert Warrior Armour. This set of armor has as much defense as Iron, but it gives bonuses for ranged weapons such as the Ender Bow. Drawback time is decreased when wearing Desert Warrior Armour.

Backstory
The Desert Warrior Armor, the totem and the well itself seem to signify there was a civilization that lived in the desert before the Player, or maybe even the Villagers arrived.
