You suffer from an unfortunate inability to communicate smoothly. While far from mute, you may have a lisp, a stuttering problem, or broken, choppy speech. People to whom you speak strain to understand you. You take a −2 penalty to checks which rely on speech, though if the check can be attempted just as easily through non-verbal means, you are not penalized. Additionally, any spells you try to cast using spoken incantation take a −4 to the roll. Th-th-th-that's all, folks!
