From publisher blurb:
Can’t get enough of popular Pathfinder system? Neither can we… that’s why D3 Adventures has started the Campaign Toybox… monthly releases of new rules, classes, and creatures to enhance your gaming experience, all priced to be friendly to your wallet at a mere ninety-nine cents, so you can afford to stock up on munchies and more dice for your next gaming session!
Our first release takes another look at that hallowed character class, the Bard, with a variety of new Bard-specific feats and spells. As a bonus, this issue also expands on the concept of the bard by introducing the Maestro Prestige class.
