Shellra III is an upgraded version of the original Shell spell, found in Final Fantasy XI. It may be learnt by White Mages at level 57. When cast, all party members in a limited area will have their Magical Defense increased. It may be recast every 17 seconds for 56 MP and, like all Enhancing Magic, its effectiveness depends on the player's Enhancing Magic skill. An upgraded version, Shellra IV, is also available.
