"This ring is meant for human use. If worn by a non-human race, while it resists diseases, it will significantly shorten the wearer's lifespan. It's often not worth it to resist illness at the cost of one's life."
The doctor commented, then offered his advice:
"You can keep the [Plague Doctor's Ring] for yourself. Although most Circle Sorcerers don't get sick, if you encounter an opponent skilled in disease abilities, this ring can be of great use. The containment method is also simple; just clean it with pure water once a month, otherwise, the wooden ring will take root and sprout."
Shard nodded in agreement; he was inclined to keep this ring rather than sell it. Such a relic with obvious functional direction usually doesn't fetch a good price unless you find a Circle Sorcerer in dire need. Thus, it's better to keep it.
