About this Mod
The "Cobblemon Outbreaks" mod is a Cobblemon addon that introduces Mass Outbreaks similar to those in Legends Arceus. In this mod, the outbreaks spawn around the player rather than being limited to specific locations. When a Mass Outbreak is triggered, swarms of Pokémon spawn near the outbreak, with four of the same species appearing initially. As players defeat or catch these Pokémon, more will spawn until all of them have been dealt with. Approximately 10 to 15 Pokémon are generated during each Mass Outbreak, with an enhanced likelihood of encountering shiny variants.
Requires:
Cobblemon v1.3.1+
New outbreaks can be added under the outbreaks file
