Dimension Baselines

Dimension rules set a difficulty floor for an entire dimension. Biome and structure rules stack on top.

Simple Nether Baseline

dimensions/nether.json

{
  "dimension": "minecraft:the_nether",
  "priority": 30,
  "level_mode": "distance",
  "level_range": {
    "min": 50,
    "max": 150

      "base_bonus": 0.0,
      "per_level": 0.03,
      "operation": "multiply_base"
    }
  }
}

Flat End Difficulty

  "level_mode": "fixed",
  "fixed_level": 200,
  "ignore_distance_scaling": true,

      "per_level": 1.0,
      "operation": "addition"
    }
  }
}

One Rule for Multiple Dimensions

Applies the same baseline to both the Nether and a modded dimension:

dimensions/underworld_realms.json

{
  "dimensions": [
    "minecraft:the_nether",
    "undergarden:undergarden"
  ],
  "priority": 25,

  "attribute_scaling": {
    "minecraft:generic.max_health": {

      "operation": "addition"
    }

Layered Nether — Baseline + Biome Spike

This pair of files gives the whole Nether a baseline while making the Crimson Forest extra dangerous:

dimensions/nether_baseline.json — applies everywhere in the Nether

{
  "dimension": "minecraft:the_nether",
  "priority": 30,
  "level_range": { "min": 50, "max": 100 }
}

biomes/crimson_forest.json — overrides the dimension rule in this biome only

{
  "biome": "minecraft:crimson_forest",
  "priority": 70,
  "level_range": { "min": 120, "max": 200 }
}
Location Rule Used Level Range
Nether Wastes Dimension 50 – 100
Soul Sand Valley Dimension 50 – 100
Crimson Forest Biome (overrides) 120 – 200
Nether Fortress Structure (overrides) (your fortress rule)
