The Flower of Falnia

"A ring made by a magician with a grave illness while researching Yggdrasil, the World Tree. Wearing it improves physical abilities and provides a slow but steady healing power. The magician's illness was too far along and he died even with the ring, but it was soon sought after by many others desiring relief from sickness. However, the ring also activates its wearer's metabolism, which can lead to intense hunger."
