Trap the Soul

You ensnare the soul of a humanoid as it dies and trap it inside the small crystal that you used as the material component for this spell. The soul remains inside of the crystal until it is dispelled or until the crystal is destroyed, which frees the trapped soul.

While a soul is trapped within a crystal, the dead humanoid it came from can’t be restored to life by any means. A crystal that houses a soul glows a varying color and intensity depending on the alignment and proficiency bonus of the humanoid whom the soul belongs to.

A creature with truesight can identify a soul trapped within a crystal by looking at it.
