This bard subclass was inspired by a song.
Bards of this subclass fall into one of two groups saints and sinners. Saints are there for the good of those around them always helping out. Sinners are there for their own pleasure and personal survival.
Mechanically you make a choice between saint or sinner which you can change whenever you level up. Depending on your choice your abilities are either going to help those around you with healing or buffing effects or damage and debuff your enemies while helping yourself.
