Flash (ability)

Flash is a recurring spell that tends to adversely affect accuracy.

Final Fantasy V
Flash is a Blue Magic spell that inflicts the Blind status effect on all enemies. A Blue Mage may learn this spell from the Headstone, Crew Dust, Ramuh, Neon, Gilgamesh, Necrophobe, Azulmagia, Orukat, Parthenope, and Stone Mask enemies.

Final Fantasy XI
Flash is a White Magic spell and can be cast by Paladins and White Mages. Flash grants the status effect of blindness, though (if both spells are unresisted) for an extraordinarily short time, only 15 seconds max. It is used often because Flash creates a high amount of enmity for the user and so it helps a Paladin gain control of the enemy's attention being fought early. Flash is cast off of the divine magic skill.
