A Dolmen is an item used during While Guthix Sleeps. When mixing the corresponding potion's ingredients on a statue in the Ancient Guthix Temple, you will receive one of the eight dolmens. When placing a dolmen on the stone table in the temple, a large dolmen will rise from the huge stone circle in the middle of the room. After all eight dolmens are placed on the table, the stone circle will raise up and unlock the door to the Stone of Jas. Oddly, the Dolmens on the stone circle disappear afterwards.
