Beetle (Final Fantasy XI) Type Species Charmable Crystal Notes Beetle is a genus of enemies in Final Fantasy XI. These insects are commonly found in the forests, caves, and mountains of Vana'diel. Beetles vary widely in their tendencies; some are docile while others are aggressive. A general rule of thumb is that beetles in forests and mountains are docile and beetles in caves and dungeons are aggressive, though adventures are always advised to use caution when dealing with these creatures. They are capable of using their gaping jaws to great effect when attacking enemies. Their shells and jaws can be useful in bonecrafting to create armor for novice adventurers.
