Environment

Coral Coves bring vibrant underwater ecosystems into cave systems. These flooded chambers feature full coral reef biomes underground, complete with all varieties of coral, sea pickles for lighting, and kelp forests. The blue color code reflects the underwater nature of these caves.
Unlike surface coral reefs, cave coral variants are specially configured to generate in enclosed underground spaces.
Exploring Coral Coves requires water breathing potions or respiration enchantments, as these caves are completely flooded.
