Examples:
Arkharon's Shock Missiles
Tables rolled on as follows:
Spell Level - 89 - Level 7 - d12 damage dice - maximum dice=10
Spell Effect - 25 - Lightning/Shock
Spell Area of Effect - 99 - Multiple Targets (divide damage into single dice)
Spell Quirk? - 22 - Yes Spell Quirk - 54 - Spell has consequential effects

How does this all add up? From the dice rolls, what you end up with is a lightning spell that generates one missile every 2 levels. Each missile does d12 damage, save for 1/2. Each missile may be sent to a different target. The spell is determined to have a consequential effects - Stun is the most fitting effect. As such, figure that a creature is stunned for one round if they fail their save.

Pulse of Light
Tables rolled on as follows:
Spell Level - 23 - Level 2 - d4 Damage Dice - maximum dice=10
Spell Effect - 75 - Light
Spell Area of Effect - 02 - Missile - Single Target
Spell Quirk? - 75 - No

This spell manifests as a pulse of light that travels from the hand of the caster a single target. The light pulse does d4 damage per caster level. If you are feeling particularly evil, you could add a quirk that the spell can be reflected by mirrors, targetting the creature whose reflection is closest to the center of the mirror!
