Separaed Soul:
The Will of Antharas is a command stone that Antharas embedded into his high commanding minions. With this stone Antharas has the ability to control these creatures to do his bidding. It is a required ingredient for creating an Antharas Blood Crystal.
A long time ago when Antharas's blood was spilt on the ground the poison in the blood corrupted the land. However, over time land acted as a filter separating the poison from the blood. The result was a pure form of Antharas blood that crystallized over time into small Sealed Blood Crystals. The power in Antharas's blood has a high concentration of regeneration and restoration power. Enough that it even has the power to bring back the dead. It is a required ingredient for creating an Antharas Blood Crystal.
