Soulflayer

Soulflayers are a type of demon in Final Fantasy XI. They closely resemble mindflayers of other Final Fantasy games. Soulflayers are among the most magically resistant of all creatures, they are magically gifted, and use a variety of enemy weapon skills that can deal damage, boost its own impressive magic casting abilities, dispel, or enfeeble characters who attack them. As if Soulflayers were not hard enough on their own, they are often in the company of undead creatures that can sense and will attack player characters with low HP.
