The steel key ring is a reward for completing One Small Favour.
If lost, a new key ring can be bought from Yanni Salika in Shilo Village for 500 coins; however, this will not bring back all of the keys on it, and (when dropped) one will have to collect them all over again.
However, the Drop trick can be used to receive multiple versions of this item (costing 500gp each). As long as you have one of them in your bank, you will not lose the keys on it, even if you lose a keyring you have on you. The Drop trick must be done before adding keys to the key ring. If you try to do the Drop trick with a full key ring you will lose all of the keys in the key ring.
The ring is an item that cannot be worn, but stores keys to save up space. All keys added can be removed. It can hold the following keys:
|Ancestral key||Allows access to the Spirits of the Elid cave north of Nardah.||Telegrabbed from the museum in Nardah. (It's called 'Key' when stored in the key ring.)|
