Mine Cells Mod

Mine Cells is a promising Fabric mod that aims to add enemies, weapons and decorative blocks from the Action Roguelite Dead Cells to Minecraft. 

You can access the new dimension in which most of the mod's contents are located by finding a specific portal in the wild, which can be recognized for its circular shape. If you haven't found diamonds before approaching it, it won't activate, so be sure to do some vanilla progression before you get started; You'll need it for the mobs and boss you'll find there. 

The Prison dimension / structure has multiple mobs to fight, most of which have their own gimmicks that may put your abilities to the test. Bringing armor and a shield is highly recommended. Across the ruined halls of this place, you will find barrels with all sorts of useful loot and most of the new weapons, including the classic Blood Sword from the game and Health Flasks.

Impressively enough, the mod also features elevators that are used to traverse some of the areas of the map, and a new boss that can be found deep inside the prison; Conjunctivius. She has multiple special moves that need to be learned, lots of health and deals enormous amounts of damage even with netherite armor.
