Quest Artifacts

[Pine Needle]

It's a good question- I've always assumed superior (and above) but that's just an assumption. With the calculator, I've found very little chance of success without a wizard, so the question was moo to me.

New quest question. Do you need to cast Bridge of Mist if you do not have the adventure trait? The text says you need it for superior artifacts, it does not mention Quest.

No, as long as you have the key you are good.

I have recently "inherited" a key for a Quest Artifact. Given that I didn't find the original quest location I don't have the code for the quest artifact. Is there any easy way to use the key to find the quest artifact or I am forced to try divining the type of artifact and hope that I eventually get the artifact that I am looking for that matches up to the key?
