(he had it in there... the Cluster Bomb Magic Trick will do 20d6, without any funny business)

Vincent
the Pyroclastic is a destructive force in the Society. He has caused
permanent damage to and condemnation of more buildings in the Inner Sea
region than any other agent. For him, incineration became an art. In
addition to the feat, skill, or other requirements listed in parentheses
for each of these tricks, you must have the Magic Trick (fireball) feat to use the trick.
Alchemist’s Inferno (Craft [alchemy] 9 ranks, Spellcraft 9 ranks): Using alchemist’s fire as a material component, your fireball
sets everything it touches ablaze. The initial blast deals half as much
damage, but targets that fail their Reflex saves also catch fire. A
creature that catches fire in this way must attempt a Reflex save
against the DC of the fireball spell to stop burning instead of the typical DC. Unattended objects automatically catch fire, though nonflammable objects burn for only 1 additional round.
Cluster Bomb (Spellcraft 6 ranks):
You are able to throw multiple small explosions with a single spell
instead of the normal effect. For every 2 caster levels, you toss a
miniature fireball
with a 10-foot radius that deals 2d6 points of fire damage. The grid
intersection of all blasts must be within 30 feet of each other. If a
creature is in the area of multiple blasts, it attempts a single Reflex
save against the combined damage.
Concentrated Fire (Selective Spell or Widen Spell, Spellcraft 6 ranks): You can reduce the radius of your fireball
by increments of 5 feet, to a minimum of a 5-foot radius. For each
5-foot increment you reduce the spell, you increase the spell’s damage
by 1d6. This additional damage can exceed the spell’s maximum damage.
Sculpt Flames (Reach Spell, Selective Spell): You can alter the shape of your fireball
to send its fire along the path you desire. When casting the spell, you
can change the area to one 5-foot square per caster level. The spell’s
area must be continuous and unbroken when cast. If its blocked or
otherwise interrupted by a 5-foot wide or larger environmental feature
like a wall, the spell fails. A creature only takes damage once from a fireball cast in this way, even if the spell’s area intersects with the creature multiple times.
Where There’s Smoke (Craft [alchemy] 6 ranks, Spellcraft 6 ranks): Using a smokestick as a material component, you make your fireball
leave behind a thick cloud of smoke in the spell’s area for 1 minute. A
moderate or stronger wind dissipates the smoke in 1 round as a
smokestick. When using a smokestick in this way, your fireball deals
only 1d6 points of damage per 2 caster levels (maximum 5d6).
