Eft (Final Fantasy XI) Type Species Charmable Crystal Notes Eft is a genus of enemies in Final Fantasy XI. The diminutive reptiles known as Efts are a common sight in Bibiki Bay. With a prominent dorsal spike, a crocodile-like jaw, and their constant location near water, it's safe to assume that they feed primarily on fish and crustaceans along the beach, but may occasionally snack on unattended bird eggs and unsuspecting rarabs. Much to the delight of beach-going adventurers, these little lizards are not aggressive, but they will defend one another if they see one of their own attacked. Don't be fooled by their small stature; with needle-like teeth, a powerful tail and toxic saliva, they can easily overwhelm a cocky adventurer.
