This drab leather tome is stamped plainly with elven lettering, appearing at first glance as little more than a journeyman’s treatise on spellcasting. Penned into almost every margin, however, are copious notes by an author who identifies herself only as “Riversong.” These annotations discuss numerous spellcasting fallacies made by the tome’s original authors and simple (yet effective) countermeasures that more martially inclined persons can use to disrupt spellcasting. The overall tone of Riversong’s notes is one of bitter melancholy, and an equal amount of space is dedicated to slanderous poetry directed toward Riversong’s parents and the book’s writers, who might be the same people.

Disruption Master (Ex) Riversong’s claims about the imperfections of spellcasting and the failings of magic provide additional insight into interrupting spellcasting. Unlike other boons, you do not spend this one. Until you prepare spells again, when you damage a foe or the foe fails a saving throw against a spell of yours, the foe also takes a –2 penalty on all concentration checks it attempts for 1 round.
