A _fireball_ spell generates a searing explosion of flame that detonates with a low roar and deals 1d6 points of fire damage per caster level (maximum 10d6) to every creature within the area. Unattended objects also take this damage. The explosion creates almost no pressure.
You point your finger and determine the range (distance and height) at which the _fireball_ is to burst. A glowing, pea-sized bead streaks from the pointing digit and, unless it impacts upon a material body or solid barrier prior to attaining the prescribed range, blossoms into the _fireball_ at that point. An early impact results in an early detonation. If you attempt to send the bead through a narrow passage, such as through an arrow slit, you must “hit” the opening with a ranged touch attack, or else the bead strikes the barrier and detonates prematurely.
The _fireball_ sets fire to combustibles and damages objects in the area. It can melt metals with low melting points, such as lead, gold, copper, silver, and bronze. If the damage caused to an interposing barrier shatters or breaks through it, the _fireball_ may continue beyond the barrier if the area permits; otherwise it stops at the barrier just as any other spell effect does.
#### Mythic Fireball

The damage dealt increases to 1d10 points of fire damage per caster level (maximum 10d10). Any creature that fails its Reflex saving throw catches on fire (_Core Rulebook_ 444), taking 2d6 points of fire damage each round until the fire is extinguished. Attempts to extinguish this fire use the spell’s save DC.
**Augmented (6th)**: If you expend two uses of mythic power, the maximum damage increases to 20d10, the area increases to a 40-foot radius spread, and any fire damage dealt by the spell bypasses fire resistance and fire immunity.
