Your songs draw upon the savage chants and brutal ways of your people, inspiring those around you to new heights of violence and savagery.
Benefit: When you use bardic performance with audible components on a battlefield (any area where a combat involving a dozen or more combatants is taking place), the range or area of your chosen performance is doubled. In addition, the DC for saving throws against your bardic performance is increased by +2 for creatures of the orc subtype, regardless of where the performance occurs.
