Spider (Final Fantasy XI) Type Species Charmable Crystal Notes These eight-legged monsters, which can grow larger than a tarutaru, can be dangerous to the unsuspecting adventurer. An adventurer can find himself slowed to a crawl, and then damaged with a high-powered slash from the talon-like legs of the spider. Additionally, spiders are armed with a damaging and long-lasting poison, which can kill the unprepared adventurer even after the spiders themselves are dispatched.
