A unique macro for Elden Ring, which does not require a limit farm and brings a significant number of runes, offers the following strategy. It is important to note that this macro has been tested by me personally and works fine on NG+3.

Before you start, use a golden scarab and a gilded bird's foot to get additional gold. This will help you get about 100,000 runes for each run and about 20,000,000 runes per hour.

So, here's how it works:
1. Download the macro and assign it to the desired profile and key.
2. Start the game and teleport to the place of grace, known as the «steep road leading to the palace».
3. Take the sword of the sacred relic in both hands.
4. Make sure that your character is stationary and not moving.
5. Run the macro and enjoy the result while the runes arrive to you in large volumes.

However, in order to achieve maximum efficiency, several important factors should be taken into account. First, be sure to have a sacred relic sword and don't forget to use talismans to increase damage. This will give you an additional advantage and increase the number of runes you receive.

It is also recommended to maintain the average workload of your character. This will allow you to use the macro correctly and achieve the highest efficiency in obtaining runes.
