by JrDemiurge

With Progressive Difficulty: Chaos Integration installed, groups of enemies in the Chaos mod gain new leaders that appear once players reach certain stages.

What it does

The add-on adds compatibility between Majrusz's Progressive Difficulty and Born in Chaos. Each group has a set chance of receiving a leader, drawn from a pool of creatures that includes the Fallen Chaos Knight, the Mother Spider, a Dire Hound, and several others from the mod's roster. Leaders appear alongside Spirit Chaos and other creatures, and a player has to fight an enhanced version of each one.

The expert stage begins after a player visits the Nether, and the master stage begins after the Ender Dragon is defeated. Stage tracking depends on Required Game Stage. The invasion undead army has its composition reworked, with new group types such as Skeleton Demoman, Door Knight, Zombie Bruiser and Siamese Skeletons replacing the earlier waves.

The mod is licensed under the MIT License and is open source. It is published for Forge only, with 1.0.1-1.20.1 as the file for 1.20.1, and it runs on both client and server, so the server and every player need it.

Key features

  1. Group leaders

    Enemy groups receive a leader at a set spawn chance, chosen from a list of creatures that stand out in each fight.

  2. Stage-based progression

    The expert stage starts after reaching the Nether and the master stage after defeating the Ender Dragon.

  3. Reworked invasion waves

    Undead army waves gain new group types, such as Zombie Clown, Zombie Lumberjack, Bloody Gadfly and Firelight Bone Imp.

  4. Enhanced leader fights

    Leaders are paired with Spirit Chaos and other creatures, and players must defeat enhanced versions of them.
