Fireball (spell)

Fireball creates an explosive ball of magic flame that expands up to the area of effect; the caster can, if wished, create fireballs of any size up to that limit. The expansion is instantaneous, as is its evaporation, which happens almost at once. The bodily cells of the recipient are torn asunder by a burst of energy — it's this surge that causes damage rather than the presence of flame; the "fire" is, in fact, incidental.
