✨ Fai’s Mythical Monstrosities
A folklore driven expansion for Cobblemon built around eerie evolutions, lunar forms, rituals, and slightly unhinged Fakemon!
It adds Fakemon, forms, lunar evolutions, and signature moves and abilities, all tied into world events and battle mechanics powered by a lunar event system!
Still in alpha, so expect bugs, balance tweaks, and lots of iteration while things keep evolving. <3
