2. Go to the Palace Approach Ledge-Road
Once you get this item, just use it wherever you are, it will bring you to Elden Ring Items exactly outside the steps of Mohgwyn Palace, now the best farm in the entire game, you need to come to this grace point Palace Approach Ledge-Road, so jump on your horse and follow the path, just run forward and ignore all the enemies and giant skeletons that will come out the ground. You’ll see the hill in front of you, the greatest point at the top of that hill is the jackpot, killing everything on the hill if you have the right weapons.
The Relic Sword you get for beating the Elden Beast, which is the last boss in the entire game, does this one swipe takes out the entire hill, and if you have them, you can use a Golden Scarab Talisman and the Gold-Pickled Fowl Foot, you'll get like plus 50 runes with both of them applied, if you do use the Gold-Pickled Fowl Foot, don't fast travel to a grace you can run to it and sit down. If you fast travel to one, you lose the buff but once you've killed all of them, you just sit back down and stand back up.
3. Shoot the bird
If you don't have the weapons or you can't beat certain bosses to get said weapons, you can always farm a bird, which is another a very popular rune farming spot, the bird you can farm it you get like 13K plus runes and you can farm in literally every 10 to 15 seconds. All you need to do is have a crossbow or a bow have arrows as well, have them equipped and hit the bird with the arrow.
If you don't want to fight enemies, use this rune glitch, this will earn you more ER runes if you're doing it for longer, definitely more efficient, and probably easier as well. You just gotta run and jump off the map and swing that weapon, but it can get a bit tedious, so it's up to you what you use. What you got to do is just stab that, just double jump through the wall, and just swing your weapon.
