Miscasting

Well, it invariably happens. You go to cast the spell, and you're staring the roll in the face. You blew it. NOW what? Well, if staff is around, you can ask them to help you interpret the miscast, but they're not there 24/7 (and even if they were, this is the system they'd use).

First, you roll 1d10. Add the Spell Level. Then add modifiers as follow:

Upset or highly emotional when casting:	+1
Spent at least 10 minutes meditating before casting:	-1
Rushed the spell (halved time for ritual spell):	+3
Casting location is noisy or unstable:	+3
Caster has successfully cast this spell before:	-3
Caster has never tried this spell before:	+3
Caster has tried and failed to cast this spell before:	+1

Whatever the final result of that total is the miscast level. This miscast level is then compared to one of the following tables, in order of relevance: quick cast spell, summoning spell, white magic, black magic.
