MobZ

Tank

Slowly but deadly. Once he was just a normal human who worked in the mine shaft but there he got infected by Zombies.

The Tank has a lot of LP but is not really fast.

Archer

The Archer should be usually friendly but he is not there to make friends. Someone said once he used to be a bounty hunter.

Fiora

Fiora, what a beautiful girl aka gold digger. Blue eyes and blond hair, what do you want more? But just pay her enough gold nuggets and she will be happy! Btw, she likes melon!

Overgrown Skeleton

I´ve never seen a skeleton so green, it probably spent too much time in the forest. But don´t overlook it, it could kill you!

Warrior

Well equipped with a sharp sword and a shield, he is probably on his way to fight something or maybe somebody? Keep out of his way, otherwise he will get angry!

Nether Golem

An Iron Golem used to live in a normal village. But one day, he got lost on the way home from an adventure and found himself in the Nether. Since then he never saw a human again. Maybe you should ask him, how he is doing!

Zombie Mage

Wululu! Mini Zombies!? The Zombie Mage found a way to capture zombies and make them his puppets.

Not every mob is listed here, just explore the world and fight against them!

Most of the MobZ Bosses spawn naturally in the Mesa Biome also known as Badlands Biome. But there is the Pillager Boss which is summonable and through him, you can get the Wither Staff which you need to summon the Withender.

First, you have to get all three parts of the Pillager Totem. Two of them you can get from the Archer/Bowman and the Zombie/Spider Mage. The third part is just a cutout of wood. Put all three together. You will need a sacrifice knife to start the ritual. The knife has to be bloody enough to conjure up the spirits but hurry up, the blood on your knife will dry out quickly. It will take 5 hearts to get enough blood flowing and then hit the middle part with the knife to start the process. You will see some smoke coming out of the totem which indicates all went right (or wrong cause you really summoned the pillager boss?!). If you somehow managed to take this boss down, he will probably drop the Staff which you can use to summon the Withender. Just build a statue as you would do for the Wither but instead of the wither skulls, use enderman heads. Sneak and right-click on the middle head of the statue and ...

MobZ is highly configurable. Just load the mod and it will generate a config file. 

Recommendation (For Fabric users only): Install ModMenu to configure the settings in the game. 

If ModMenu is installed, just open the Mods tab, search for MobZ and click on the gear wheel at the right top side.

Forge has its built-in equivalent of ModMenu.
