Barfira is an Enhancing Magic learned by White Mages at level 17, serving as the area of effect version of the Barfira spell available to Red Mages and Rune Fencer. Its scroll can always be purchased from Hasim in Lower Jeuno.
When cast, party members, in a limited area of effect, will have a higher chance of avoiding damage from Fire-based spells, and taking decreased damage from Fire-based attacks. It may be recast every 10 seconds and its effectiveness varies depending on the player's Enhancing Magic skill.
Should a player have a White Mage as their sub-job, their character will have access to Barfira once reaching level 34.
