This spell changes the natural properties of a precious gem, restructuring the crystal lattice into a devilish trap to store a creature’s soul. The targeted gem becomes a dark, murky purple in color and loses any properties it once possessed, forever transforming into a soul gem.

More powerful souls require more valuable gems to trap them. A gem must have a value of at least 1,000 gp for every Hit Die possessed by the creature to be trapped. If the gem is not valuable enough, it shatters when the entrapment is attempted.

(Note that this spell only creates empty soul gems and does not trap souls in them.)
