Captures the soul of any creature dying on the current map while you're wearing it. The ring will annotate itself with the name of the soul it currently contains.
If you happen to find a ring of soul trapping other than the one you started out with, it'll be a ring of delusion.
- Wearing this ring prevents HP boosts through black gems as it traps all of a soul's energy within.
- You can change the annotation with the NAME command, but the imprisoned soul remains the same.
