If there is one class in Final Fantasy XI that is very enjoyable and exciting to play it is the ninja. This ffxi ninja is available only to players who have reached level 30 and who have completed the ninja flag quest. What makes the ninja exciting? Because it combines the best combat moves with powerful spells. One unique spell that the ninja can cast is called the Utsusemi which creates shadows. Ninjas can create three to four shadows at a time. The ninja also has the ability to slow down enemies and can even blind or paralyze them through the spells that it can cast.
