Silver medals are made by using two silver nuggets on the forge at Gielinor Games preparation. Seven of them can be handed in to Oomad Arrow every day in return for contribution points and Smithing experience.
Players can make more than seven, but all would be taken when handing them in. They cannot be dropped or banked.
The Smithing experience is rewarded when handing them in rather than when making them.
