And Pig World Revolution in update 4.1:

MOD IS NOT UPDATED BECAUSE OF COMPUTER DESTROYING
HERE IS THE CONTINUATION:

Mod has 3 new portals - the world of magicians and the pig end, if you prefer the world of gold and ancient portal . An ancient portal, i.e literally antique, there will be mythological creatures or gods, e.g Zeus. The advantage of my modification are heavier bosses and some monsters. I had enough of killing Ender Dragon in iron, gold or diamond armor without a spell. Here, to kill Margrung, you must sweat to get wards, spell potions and the strongest armor. This is my first mod, so it can have many bugs. I hope that the fight with bosses is not monotonous, but interesting. Mod is really difficult at times.

Curiosity

In the modification there are 80+ creatures and monsters, 40+ structures, 3 portals, there may be 4, 10+ new ores in the future. Each boss is original, so the fight with each boss looks different. The mod is made by Mcreator

On the mushroom biome you will find a monster that cannot be killed in a standard battle. this is Hairy Troll. To kill him, you can use an Iron Golem, TNT, potions or a wand

Dimisions

Wizard World:

If I were to assess the difficulty of bosses, I would say that there are only two bosses as strong as ender dragon.

Anti Heroes

Anti Heroes are bosses that respawn randomly on a given biome in the world. Their task is to kill an unprepared olayer for battle. I plan to add orbs from them, but I have no idea what could be done with

A few sample bosses, monsters and animals:
Earth Elemental:
