Cataclym adds new dungeons into each of Minecrafts dimension, which are challenging. Each one contains a main boss fight, though there are other foes to defeat. Doing so will give you some new weapons and armor, which will help you progress not only through other dungeons, but your game as a whole.
In total, there are five dungeons spread throughout the Overworld, Nether, and End, with more likely to come in the future. In these locations, you can fight bosses like the Ignis, Netherite Monstrosity, Harbinger, and Ender Guardian.
