The gold bowl is a quest item used during the Legends' Quest. Vaguely yet obviously described by Gujuo, the required vessel is a bowl "made from the metal of the sun". It is made by using two gold bars on an anvil while holding the sketch given to the player by Gujuo; after completion of the quest, it is possible to make the bowl without the sketch, though there remains a chance of failing. This gives 30 smithingexperience. The bowl must then be blessed with Gujuo's help to turn it into a blessed gold bowl. The blessed version is the only vessel capable of holding water with holy properties; trying to fill a normal gold bowl with the pure spring's water will yield a message along the lines of having mere normal water. A successful fill will result in a message saying that "the water seems to bubble and sparkle as if alive."
There is a chance that the player will fail in making the gold bowl, causing one or two gold bars to be destroyed without a resultant bowl. When successfully made, 30 smithing xp is gained and a message of the achievement appears in the chat box.
Multiple gold bowls may be made during and after the quest to efficiently produce large amounts of Holy water. They will, of course, have to be blessed individually by Gujuo.
