Flash of Light

Flash of Light is designed to be the Holy Paladin's quick cast heal. It is considerably faster than Holy Light or Divine Light, and is more powerful than Holy Light, but is the least efficient of the three spells. A Holy Paladin who casts Flash of Light too much risks running out of mana.
