Sever Lifeline

This spell permanently detaches the caster from his lifeline. This negates the rule concerning doubling lifelines, and that's all most casters know.

The material components are a small silver knife enchanted to store a tether, and diamond dust worth 10,000 gp, sprinkled across the blade. This spell is cast on Temporal Prime, and the knife is used to physically sever the chronomancer's lifeline at the point it turns into the insubstantial silver mist trail.
