Fireball

Fireball creates a tiny ball of fire that flies forward from the caster, exploding in a huge fireball at a point designated by the caster. While an extremely potent spell, the caster must take care to avoid catching allies in the explosion, or to accidentally strike an obstruction and detonate the spell early.
