Extra Draconic Aura +4

These auras can be activated to grant benefits to you and your allies around you, and stay active until you change to a different one. You can only have one draconic aura active at any given time. Auras used by those without the Dragonblood subtype have a bonus of +1. Those with the Dragonblood subtype have their auras increase in power to +2 at level 7, +3 at 14, and to a maximum of +4 at 20.
