The Fireball spell is a core Mage ability. Casting Fireball creates a slow but deadly ball of flame the hurtles towards enemies. Upon impact, the Fireball explodes into a spray of fiery plasma. Casters should take care with this spell, as this spray can damage the caster as well. If the Fireball catches unexpectedly on a surface too close to the Mage, it can easily kill the caster or any of his or her allies.
