Can you MQ all the Coldain rings?

[Tobius]

Would like to get dain ring for my brothers char, really don't want to skill up tradeskills again.

Is it possible to say, get as far as the quest with the Coldain skinning knife, give it to his char and hand in the ring, and he hads in the knife.

Or some other point in the first 8 rings where we could swap ownership of the rings somehow?

Also for ring nine, where you kill all the traitors, does every alt have to raise their brewing skill to that horrible amount? Or can one person knock the mob out with the tonic and the other character takes charge from there?

Thanks.
