New Player Advice: Never Sell ANYTHING
There is absolutely no need to sell a single item while you play through Elden Ring and learn the game. Of course this is all my personal opinion and friendly advice!
I’ve seen many posts over the years of enthusiastic newcomers accidentally selling an important piece of equipment… and then becoming distraught learning that there’s no way to get it back. (without starting over or having another player drop one)
Rune items can be used from the inventory to reduce the risk of accidentally selling the wrong item. They can be used in bulk, and I know this is slower than selling in bulk… but it’s not that much slower.
Also, it will help new players understand that there’s an infinite number of runes out there to go acquire… just take your time and enjoy the game. It’s not worth potentially losing something important to buy an item… almost everything you can purchase you should have no problem farming runes for.
