Im using the mohgwyn palace sacred relic sword farm supposedly its the best farm i was wondering are there any better ones i only tried it out today and i got about 11 million runes in an hour and a half so pretty good but is there any better ones?

As of right now no, that's the best place for farming runes. You could technically do the map glitches that they haven't fixed, but they're quite difficult to pull off compared to the original and their payout isn't nearly as good. Killing the bird/albinaurics are probably your best bet.

Don't forget to equip yer Golden Scarab Talisman and pop a golden pickle foot for best results! The pickle foot effect doesn't reset after resting at a grace, so work fast to get the most bang out of your buck.

Still on my first playthrough and bit more to do. So far only figured out how to get about 80,000 in about 3-5 minutes. you must be getting around 550,000 every 3-5 minutes That's seems pretty good.
