About this Mod
This second mod created by Phax709 aims to challenge players in an entirely new dimension called Chaos (Chaosium), featuring powerful creatures, unique blocks, and much more.
– Pyronis: a fiery ore that can defend you with flames and protect you through its armor.
– Melanterite: an ore difficult to distinguish due to its color being close to Minecraft’s lapis lazuli.
– Lazurite: allows you to create the portal to the new dimension.
– Various creatures, each more powerful than the last.
– Armors capable of withstanding any creature’s attack.
