Once in a century a Stonetalker might stumble upon this most valuable of stones, a natural Obsidian Gem that falls from the rock face at a Stonetalker's touch. When discovered an Obsidian Soul is empty and sleeping, but a Stonetalker can make an Intelligence + Healing / Stones roll resisted by a 16 to wake it. Once awoken an Obsidian Soul must be carried close to the body. When the one wearing it dies their soul and spirit passes into the stone. If their body can be restored to positive Health, and the Soul breathed upon by a Stonetalker, then their spirit returns to their body and brings it back to life. When this happens the Obsidian Soul cracks, and no longer has power.
Only a Stonetalker can identify such a stone. They must be in the deep Obsidian hills, spend at least two weeks searching, and succeed in an identification roll resisted by a 40 (see Stonetalker rules).
