About Custom Entity Attributes (CEA)
From ModrinthChange 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.
