As I mentioned before, Vance doesn't rely on his spells, instead
using them more as backup.  He only keeps three or four spells racked at
a time.  They are as follows:

Hellfire
Lynchpins: Checkspell, Magic of Shadow, Buildup, Target gesture.
Description:  This is an extremely deadly spell - so deadly, that an extra
lynchpin is necessary just to monitor the buildup of energies.  After the
checkspell lynchpin determins that the spell is intact, a black sphere
forms within the caster's grip.  Inside the sphere, energy builds up,
superheating the air inside.  When the buildup is complete, the caster
points the sphere in the direction of the target, and makes a releasting
gesture.  At this point, the sphere bursts open, and a white-hot bolt
fires at the target (this spell is sometimes called 'Plasma Bolt' in
high-tech Shadows, for good reason).  The caster must release the bolt
within a few seconds of the buildup being complete, or the sphere will
rupture (which could be serious if the first fracture occurs in the
direction of the caster).  The bolt should be able to blow through a man
in full plate armor, shatter a passive magical shield, and otherwise be 
deadly enough where the best defense option is 'don't get hit'.

Reversal
Lynchpins:  Checkspell, Magic of Shadow, Target gesture, Trigger word.
Description:  The Reversal spell doesn't do anything immediately when
cast.  Instead, it is held active until released by word and gesture.
When an energy-based attack (whether mundane or magical) is used in the
immediate area, the caster can gesture towards it, and it will immediately
reverse its course (or be keyed to do so, if it hasn't been released yet).
There is some control allowed in the process of reversal, and the chance 
of hitting depends on Warfare.  Spells that target based on a Psychic link 
cannot be reflected.  The Reversal spell only works against one attack, 
though the energy manifestation can be of any size.

Wind Blast
Lynchpins:  Checkspell, Magic of Shadow, Direction, Target gesture.
Description:  Wind Blast redirects the local atmospheric gases to produce
a strong gust in a particular direction.  The initial blast is at full
strength, and then the winds fade until it eventually dies out.  The
strength of the wind blast depends on the current movement of atmospheric
gases (how fast the wind is blowing) and how thick the atmosphere is.  It 
generally doesn't reach hurricane strength, though it is possible if the 
weather is already turbulent.

Sparkle
Lynchpins:  Checkspell, Magic of Shadow, Dispel Word.
Description:  Sparkle produces an aura of magical energy that extends into
the visible spectrum.  This aura appears around the caster's hands, and
throws off sparkles as the caster makes hand movements.  The energies will
fade over time, or can be negated with a word.
With an extra lynchpin, 'hand-gestures', the special effects can be 
varied.  Sparkles can be changed to juggling lights, brightness can be 
adjusted, and so forth.
