Magic Minstrels
From NsdWiki
Magic Minstrels differ from regular magi in that their Magic Points are determined by Presence instead of Intellect.
By gaining ranks in the Magic Song special power, they can increase the number of targets affected by the spell, if it would normally only allow for one target.
They can only "sing" spells out of the Sound School, Charm School, Illusion School, Status School, and Perception School.
