Without crafting, you can just farm the Black Scimitar without using any skills and you can make more RS gold just within an hour.

Where to get the Black Scimitar and sell it for RS gold

The Black Scimitar is a type of Scimitar which has slightly higher damage than the steel Scimitar. In order to wield it, a level 25 attack is required. You can find the Black Scimitar at the Ardougne Castle and at the Shades of Mort’ton mini-game as an obtainable reward but requires a steel key. It is easy to get this kind of weapon and one of the best ways to make more RS gold.

 

In order to start farming Black Scimitar, head to the East Ardougne and head up to the second floor of the castle. The Black Scimitar is just simply lying on the ground around the area so you can just pick it up. It will spawn every 5 to 10 minutes. Once you have an inventory full of Black Scimitar, head back to the city and sell it for RS gold.
