Shard Soul

The shaman gains DR 3/magic. This DR increases by 1 for every 4 shaman levels she possesses beyond 8th. In addition, as a standard action she can cause jagged pieces of bone to explode from her body in a 10-foot-radius burst. This deals 1d6 points of piercing damage for every 2 shaman levels she possesses. A successful Reflex saving throw halves this damage. The shaman can use this ability three times per day.
