Kartan's Variable Volume Fireball (3.5e Spell)

Kartan's variable volume fireball produces a fireball that causes an explosion of flame that detonates with a low roar and deals 1d6 points of fire damage per caster level (maximum 15d6) to every creature within the area. Unattended objects also take this damage. The explosion creates almost no pressure. There are, however, modifications to this spell that the caster can make upon casting. Other than these modifications, this spell is in all respects a fireball spell.

Upon casting the spell, the caster indicates whether the spell has a greater or smaller radius than the usual 20-ft. radius. For every 5 feet that the radius decreases, the spell's damage increases by +1 per die. For instance, Kartan casts this spell at a two adjacent targets, and so makes the radius of the spell 5 feet (affecting a 2x2 square area on a map). This is a three-step decrease in radius (20 to 15, 15 to 10, and 10 to 5), thereby increasing the damage to d6+6 per die. If Kartan is 13th level, this spell does 13d6+39 damage (but only to those two targets).

Similarly, for every 5 feet that the radius increases, the spell's damage decreases by -1 per die (to a minimum of 1 point per die). Kartan casts this spell at a whole horde of orcs, and increases its radius to 40 feet. This is a four-step increase in radius, so the spell does d6-4 per die of damage (minimum of 1). As Kartan is 13th level, this spell does 13d6-52 points (to make things easier, roll 13d6, count every result as a 1 unless the die shows a 6, in which case it's a 2).

This spell's minimum radius is 5 feet and its maximum radius is 45 feet. These may be altered by certain metamagic feats.

Material Component: A tiny ball of bat guano and sulfur.
