Covenant of Io
Prerequisite: Dragonborn, dragon breath racial power, invoker, Divine Covenant class feature
Benefit: Your dragon breath power is considered a divine attack power. In addition, when you use an invoker at-will attack power that has a burst area of effect, you can choose to make it a close blast 3 instead of an area power. The other effects of the power are unchanged.
