Mimicology Quests are Sidequests assigned by Cypress that involve collecting a certain number of specimens (e.g. body parts) which are dropped from Mimics, left over from the burn-up process. Receiving a specimen is not certain when most mimics die so you may get other items; the exceptions are the special studies which add mimics on the ground. After the first, studies are chained so each requires a previous one to be completed. Each also requires having killed at least one Mimic of that species to access the quest.
