Buddy Rings can be used to release new buddies, or to level up buddies you already have. You can also equip a Buddy Ring to a party member, enabling them to use the buddy-specific skill attached to that ring.
Throughout the game, there are a limited number of monsters who drop Buddy Rings. The rings are always an ultra-rare drop, meaning you'll need a character with a high level Steal attached to their weapon - or you may need to use Toril's Brave Strike, "What's yours is mine," which automatically steals all normal, rare, and ultra-rare drop items.
Listed below are all the monsters I've encountered that drop Buddy Rings. (Note: I have completed every area except for the lv. 900 region)
