Upon manifesting this power, you choose cold, electricity, fire, or sonic. You weave a field of potential energy of the chosen type around your body. The first successful attack made against you in each round during the power's
duration prompts a response from the field with out any effort on your part. The attack may be physical, the effect of a power, or the effect of a spell (including spell-like, supernatural, and extraordinary abilities). An "ectoburst" discharges from the field, targeting the source of the attack and dealing 4d6 points of
damage of the chosen energy type. To be affected, a
target must be within close
range, you must have line of sight and line of effect to it, and you must be able to
identify the source of the attack. The ectoburst is a ranged touch attack made using your base
attack bonus plus your key
ability modifier for your manifesting class.
This power's subtype is the same as the type of energy you manifest.
