Correction - I finished the quest without using the required Leather Gloves and Boots. I was wearing Dragon Gauntlets and Dragon Boots at the time I did the quest. I believe any combination of the various gloves and boots in Runescape would work for the quest. Reason - Perhaps save players who are already wearing gloves and boots some time standing at the G.E. by adding a little footnote or changing the requirements to "any gloves and boots". Edit - Maybe also mention that an Opal can easily be obtained in the natural course of the quest by panning by the river, this would have personally saved me 10 minutes waiting on G.E. ( Yes I know I could have saved myself the time by reading the item list's entire purpose is to save time, so why not go 100%? )
