Flash of Light is a level 4 paladin ability, designed to be the Holy Paladin's quick cast heal. It is considerably faster than [Holy Light], but is the least efficient of the two spells. A Holy Paladin who casts Flash of Light too much risks running out of mana.
Flash of Light is a fast but expensive heal. It should only be used when speed is the most important consideration (ie someone is about to die, and won't live long enough for Holy Light to go off) and when [Holy Shock] is not available.
