Chaosium
by Phax709
Chaosium adds a new dimension called Chaos, reached through a portal built by the player, along with armor, blocks, ores and strong creatures.
What it does
Players who are well equipped can travel through a portal into the Chaos dimension and challenge its bosses. The dimension holds creatures that are stronger than the usual enemies, plus blocks found only there. Armor is needed to withstand their attacks.
Chaosium runs on Forge and NeoForge, with files for 1.20.6, 1.21.1 and 1.21.4. It is client and server, so the server and every player need it. The mod is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source. Its latest Forge build is 1.0.0 for 1.21.1, and its latest NeoForge build is 1.0.0 for 1.21.4.

Strong creatures
