Divine Shield

You can sheath yourself in a nimbus of power fashioned from raw positive or negative energy.

Prerequisite(s): Channel energy class feature.

Benefit: As a standard action you can expend a use of your channel energy ability to create a shield around yourself of positive or negative energy – depending on which kind you normally channel. This shield lasts for a number rounds equal to your level. During this time any creature striking you with a melee attack will take 1d6 points of damage, as long as they would normally harmed by your channelling. Creatures are also permitted a Will save as normal to reduce this damage by half. Creatures can also touch you as a standard action to be healed for 1d6 points of damage if they would normally be healed by your channelling. This damage or healing increase to 2d6 at 5th-level, and then by an addition 1d6 for every 5 levels thereafter, to a maximum of 5d6 at 20th-level.

Normal: Channel energy

Special: You can use this feat again while your divine shield is still active to increase its duration by a number of rounds equal to your level.
