A ring of regeneration was a magic ring that gradually and continuously healed the wounds of its wearer. Every ten minutes, the ring of regeneration emitted a burst of recuperative magic, restoring part of the health of its attuned wearer. It was also capable of regenerating lost limbs, in a process that took a few days.
The incredible magic stored in these rings were used by a variety of adventurous Mortalkind, from warriors who depended on quick recovery to healers who used them on their clients.
