Legendaries

A random Legendary Pokémon appears approximately every six hours in Aetheria (6:00, 12:00, and 18:00 UTC). The countdown between these spawns only begins once the most recent Legendary has been caught, defeated, or despawned. Spawns occur on a specific player, regardless of biome. You can check the previous spawn by using the command "/spawnevent".

Rarity

Certain Legendary Pokémon spawn more frequently than others. They can also be obtained from crates.
