Seed Ring

Seed Rings are items that appear in both The Legend of Zelda: Oracle of Ages and The Legend of Zelda: Oracle of Seasons. They are rings that contain special abilities that are activated when Link has one equipped, for example, some help Link deal more damage and some have beneficial effects on Link's items, while some have novel effects that doesn't help Link out as much as being humourous.

Seed Rings can be found in chests, be bought in shops or be given to Link from other characters. When one is obtained, it must be taken to Vasu in Lynna City for appraisal before it can be used. For 20 Rupees, Vasu will appraise one ring, and inform Link about its abilities. When Link visits Vasu, Link is given a Ring Box to store the rings in.

To actually equip a specific Seed Ring, Link must talk to Vasu and choose "List". Then Link can put one Ring in the Ring Box to carry around with him at all times. However, there exist upgrades to the Ring Boxes, which allow Link to carry a maximum of three and ultimately five rings. However, only one can be equipped at a time.
