Fulgar

The Sosarian arcane spell Fulgar is the second of the combat-minded spells available to the Sorcerer, and stronger than Mittar. Casting it sends a hot fireball against a selected, single target, causing serious injury; and death to lesser foes.

Note however, that this spell only goes against a single foe. To attack a group of foes at the same time with fireballs, the spell Noxum is needed.
