If you've managed to get to RuneScape Gold the top of the Pyramid then take the object lying there and return to the NPC whom you previously spoken to. He will now pay you 10k gold per Pyramid Top that you bring to him. Repeat this process the duration you wish.
In the beginning, you'll need to enter the Great Kourend which can be reached via boat from Port Sarim. Once you arrive at the port, talk to Veos who is located to the south of the inn. Ask him to guide you to Port Piscarilius. From there, you can travel to the west until you reach Kourend Castle. Just outside the castle's gates is an enormous Obelisk. You can look it up to enter the cave.
Then, you should go south until you can see cracks in the wall . You can squeeze through it. Then, go to the west, and you are able to fight Twisted Banshees there. There's a safe area from which you can shoot Banshees that are located in the south-west corner of the area.
While you may not make the same amount of money with other strategies however, you can be able to train and earn additional gold. In addition ensure you bring high Alchemy runes in case you are able to use that spell as they will drop items such as Battlestaves as well as Adamantite Shields.
Start by entering the trapdoor that is located to the north west in Lumbridge Castle. Once inside the cave of the cultists, walk behind the man who talks to cultists . There - just beneath the wall - there is a secret trapdoor. If you aren't able to Buy RS Gold see it, then you probably haven't finished your Death of the Dorgeshuun quest. Inside, you'll discover H.A.M. guards , and these are your target. Similar to the previous method you should carry some High Alchemy runes to maximize the profits.
