Paradox fireball: Destruction
Magic is used to draw nearby heat energy from the environment, and concentrate it inside a tiny point at the tip of the caster's finger. The spell prevents this energy from being released until it collides with either a solid or liquid mass, at which point it violently releases the energy collected in a fiery explosion. When the caster is ready, the tiny ball is fired from the tip of the finger at very high velocity. It is said to be difficult to aim, but with sufficient charge time, causes sufficient splash damage to not be that important. If held for extremely long periods of time, enough thermal energy is collected and sequestered to cause the material overlapping the concentration point to undergo spontaneous fission reactions, which are likewise contained until released. MP cost increases the longer the spell is held/draws heat from the environment. Heat energy is drawn from a [10*spellLevel]-foot spherical radius around the caster, but does not affect the caster him/herself. This effect can extinguish sources of open flame, as the heat needed to sustain the fire is pulled away magically.
Components--
Visual: Small orb the size of a small pebble is suspended about 2 inches in front of the caster's index finger, which glows brightly. Curls of frozen water vapor drip from around the orb, as all heat energy is drawn into the orb.
Auditory:
A faint hissing to a loud crackling noise is emitted from the orb, as it gains energy/is cast at higher spell levels
Somatic:
Caster must be able to point the finger at the desired target to cast.
