Vizzaroli’s Distort Speech

By making physical contact with the target for 30 seconds you release the power of the spell. The target attempts to speak, but spews forth only gibberish instead.

For the duration of this spell, the subject has a 50% chance to miscast spells that have verbal components, and any time the subject speaks (including the use of magic items activated by command words), there is a 50% chance that the utterance is completely incomprehensible and therefore ineffective.
