Ripping a hole to the positive energy plane, you cause a column of positive energy to rip up and overload your opponents. Everyone affected takes 1d6 points of positive energy damage per caster level (maximum 20d6), or 2d6 points if the target is undead or otherwise weak to positive energy (maximum 40d6). Against creatures native to the positive energy plane (like ravids) or constructs, there is no effect. The energy ignores nonliving material and reaches high into the sky for all to see, often even through the tops of buildings. The spell is often erronously called Holy due to it's effectiveness against evil undead, but it can harm any living (or unliving) being regardless of alignment.
