What happens to a lich's soul when it dies with a Ring of Mind Shielding? Normally, a lich's soul goes to the phylactery. But the Ring of Mind Shielding also takes a soul. Does the lich choose where to go or does one overrule the other?
My interpretation is, the ring takes the soul. The wording on the ring says:
If you die while wearing the ring, your soul enters it, unless it already houses a soul. You can remain in the ring or depart for the afterlife.
That sounds like the ring takes the soul regardless of the soul's desire. However the soul can freely leave the ring, though it'll be a one way trip to the afterlife. But in a lich's case, it'll go to its phylactery instead.
If this is a correct interpretation, a lich can use this ring to kind of treat it like a backup phylactery? (Possibly a cursed item for an awesome story?)
