A small addon for the Enhanced Celestials mod, created in 10 minutes in MCreator for the Nihonium modpack. Which will be released sometime in late 2023 (hopefully). The addon adds a special item through which you can summon the Blood Moon by pressing RMB on any creature. The item drops from a zombie with a 10% chance.
