Power word

This spell draws a bright rune of power in
the sky. The spellcaster may pick one spell for
the Power Word to affect. All rolls to cast that
particular spell are at +3 for every
spellcaster for the rest of the game.
A spellcaster may only have one Power Word
spell in effect at a time. Only one Power Word
can be active for each specific
target spell at one time.
