About Custom Entity Attributes (CEA)

From Modrinth

Change entity attributes globally, per dimension, biome, difficulty, or time. With % chances too!

What's CEA?

Custom Entity Attributes allows you to add attribute modifiers to entities, either globally or based on various conditions, such as the dimension the entity is in, the biome, world's difficulty, time, and more. It even includes a percentile chance of the attribute applying, making randomness possible.

With this mod, you can:

  • Make any mob or boss stronger, or weaker.
  • Make entities have different attributes in a specific dimension or biome.
  • Make entities have a small chance of having extra attributes, giving some variation to all entities.
  • Make baby versions of mobs be faster and stronger but have less health.

...and more! It's all up to your creativity, as attributes are really powerful!

Requires Necronomicon 1.6.0+ Also requires Connector in Forge
