Circle of Stone (Cooperative)

This spell can be cast in any location in which pieces of stone larger than the caster surround him or her on at least three sides. The spell involves a short chant and the physical linkage (touching) of all the beings to be encircled. It creates an invisible, magical field around them.

The field is spherical, with a 10-foot radius per caster involved. While it lasts, it confers a bonus of +4 to the saving throws of all beings in the circle, and a 5-in-6 chance that any spell or magical item effect originating outside the circle is reflected back at full power on its source.

Dwarves within a circle of stone gain a +3 bonus to attack rolls (not damage) and are empowered to hit all opponents, even those normally struck only by magical weapons of certain bonuses.
