Aoa are fictive creatures in the Dungeons & Dragons setting. These outsiders are born from the friction caused as a result of the rare occurrences when the Negative Energy Plane and Positive Energy Plane graze each other.
Aoa naturally reflect most attacks and spells. Since aoa reflect energy, scholars theorize that they may be a neutral counterpart to energons, such as the positive-energy xag-yas and negative-energy xeg-yis, which produce energy. Aoa can also release a pulse about three times per day that reflects magical energy back onto itself, which may destroy magical auras and shatter magic items.
