Fireball

For the Vaal-themed counterpart, see Vaal Fireball.

Tapping into the chaotic, hungry elemental force of fire, the caster sends a roaring ball of flame hurling at the target. This searing projectile flies unerringly outward, impacting with tremendous force, and burning not only the target, but adjacent foes as well. Skilled wielders of flame can ignite the enemy, causing them to burn for additional damage. A master of the fireball lays waste to all who beset him, reducing his enemies to cinders.

Description on the official Path of Exile website

Fireball is a spell that fires a projectile, dealing fire damage with an increased chance to ignite.
