The Robe of Elidinis (top) is a robe top that is required in the Spirits of the Elid quest. The robes are created by using a needle on the torn robes found in the shrine in Nardah during or after the quest. The player must wear the robes in order to enter the Water Ravine Dungeon farther north along the River Elid. After the quest, players may use the robes to continue to access the dungeon, although few do.
You can get a new set of robes by searching the cupboard again for the torn robes and then remaking them with needle and thread. You cannot get another set of torn robes if you already have a set of torn robes or robe of Elidnis in your possession (including in the bank). However, you can use the Drop trick to get extra sets by dropping your robes before searching the cupboard. This gets you a new set of torn robes, which you can mend when you wish.
Some players believe that the Robes of Elidinis provide better protection from Desert heat than Desert clothing does. However, the Robes of Elidinis actually provide no protection from desert heat at all.
