Progressive Difficulty: Chaos Integration

This mod creates compatibility between two popular modifications: Majrusz's Progressive Difficulty and Born in Chaos. It introduces significant changes to gameplay by adding new types of enemy groups and completely reworking the composition of waves during the undead army invasion.

New Enemy Groups

The game features special enemy groups that can appear with a certain probability when a leader spawns. It's worth noting that the "Expert" stage begins after visiting the Nether, while the "Master" stage starts after defeating the Ender Dragon.
