The College of Dirges

The Banshee's college is what happens when a Bard College is founded in honor of the Banshee's legend.  Officially named the College of Dirges, what sets these bards apart from others is that where a common bard's tale will bring laughter, a Dirge Bard's will instill dread.  Where another's bard song will inspire a warrior to legendary feats, A Dirge Bard's music will sap him of his strength and leave him crumpled in the dust.  The College of Dirges is the study of how to weaken your enemies to impotence, and destroy them with a song.

Demoralize
