FFXI wiki icon Barvirus is a Enhancing Magic spell in Final Fantasy XI. It can be learned by Red Mages (level 39) and Rune Fencers (level 38). When cast, the player's resistance to the Virus status will be increased, decreasing the duration that the player is afflicted by the status effect. It may be recast every 10 seconds for 25 MP and its effectiveness depends on the player's Enhancing Magic skill. Those using White Mages have access to an upgraded version, Barvira.
