By concentrating, you can extend the area affected by your aura of courage.

Prerequisite(s): Aura of courage ability

Benefit: As a standard action, you may make a concentration check. The DC for this check is equal to the desired size of your aura of courage – for example, an aura twenty feet in radius would be DC 20. If the check succeeds, you may maintain this expanded aura as long as you concentrate.
