i just started doing the quest. i'll try to make something up on how to do it. you'll first need to get a raw tuna, or then you can buy it from the isles, there's a bank in there. i think a catspeak amulet would help a little bit maybe. the quest is pretty easy, since you can get like, everything from the isles. the six mith ore can be obtained there as well. not recommending the mines near the isles, many people there and only about four mithril rocks.
