Banishga

Banishga is an upgraded version of the original Banish spell, also known as X-Zone, found in Final Fantasy XI. It is a White magic spell, that deals light-based elemental damage to all enemies in a limited area of effect. The spell is particulary effective against undead, and may also lower an undead monster's defence. Banishga may be learnt by White Mages at level 15. It can be recast every 30 seconds.
