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.
Notes: Rare spell, granted only by dwarven gods.
