Barpoison is a White Magic spell found in Final Fantasy XI. It can be learned by Red Mages at level 10. When cast, the spell decreases the duration for the player being inflicted with the Poison status effect. It may be recast every 10 seconds for 9 MP, and, like all Enhancing Magic, its effectiveness changes depending on the player's Enhancing Magic skill. Players utilizing White Mages have access to an upgraded version, Barpoisonra.
