Defeating them will make them drop food, but Cu Chaspel can summon more. It is highly recommended to defeat them to avoid being damaged too heavily while trying to defeat the main target. If Cu Chaspel is defeated while any clones are alive, the clones will automatically die with him.
[view·edit·purge]In biology, cloning refers to the natural or artificial process of producing similar populations of genetically identical individuals. The term is derived from the Ancient Greek word κλών klōn, "twig", referring to the process whereby a new plant can be created from a twig.
More generally, the word "clone" means a duplicate or copy of something.
