Gnat (Final Fantasy XI) Type Species Charmable Crystal Notes Gnat is a family of enemies in Final Fantasy XI. The countless dead left in the great war's wake served as a nearly limitless breeding ground for opportunistic pests such as the gnat. Without discrimination, these flesh-eating pests buried their eggs within corpses, which served as a food source for newly-hatched larvae. It is believed that feasting on the flesh of dead mages - on the Mindartian continent in particular--somehow triggered an evolutionary abnormality resulting in a formidable array of gnashing teeth. Once the unfailing acuity of the gnat's sense of smell became common knowledge, the distinctive buzzing of the gnat's approaching wings was considered a sure harbinger of death among soldiers.
