The economy of Elden Ring is...uneven, I guess. Although it is possible to make a living as a merchant in the Lands Between, it is far more lucrative to murder a large number of people and rummage through their belongings in search of valuable runes. In spite of this, it's likely that you'll pick up a few items—perhaps even twenty—during your looting spree, some of which will prove more valuable than others.
The profit from selling these products won't be great, maybe a couple hundred Elden Ring runes, but if you hate having a cluttered inventory, it's a good idea to contact a merchant and get rid of the extra weight. In the early game, when nearly everything can kill you, every rune counts. A lot of hard work is required to reach the level of Elden Lord.
A Piece of Ruin
One of the most striking features of Limgrave, and the Lands Between more generally, is the number and variety of ruins that have been left behind. The little stones that sparkle across the surface of the strewn wall fragments will lure even the most jaded traveler to investigate. Are they hidden in the lore of the realm like so many other little objects in the Soulsborne games? What mysteries do these objects hold?
I'm afraid not very much. The item description alludes to a temple that was destroyed when it fell from the sky, but other than that, they have little use outside of the production of Rainbow Stones. Trading them in for some runes at the beginning of the game could be helpful.
The potential benefits of Grace Mimics are immediately apparent. Make your own saving grace that will point you in the correct direction. Awesome!
But this phony haven of grace doesn't really help. Even though it looks to be designed for PvP, you shouldn't rest at it because its putrid ray travels in what seems to be a completely random path. Patches's willingness to sell them should tell you everything you need to know. The most you can say about these humorous things is that they will amuse your pals. Even though you'll only get ten runes for each Elden Ring item, it's better to have some money than to have these items taking up space in your warehouse.
Stones suitable for use in making simple tools
You will receive a large quantity of smithing stones at level one or two, and you should hold on to them for the time being. Also, you can easily find these, and they are very helpful if you want to compare a new weapon to your current main. To see them laying on the floor, all you have to do is enter a cave.
There is always a market for first-level smithing stones, and if you're in need of a few runes, this would be a great item to pawn. Avoid passing on any items with melancholy or old dragon in their names. Rare stones like these can fetch astronomical sums since their value much exceeds their retail cost.
The success or failure of Beast Blood Elden Ring's crafting mechanism hinges on the player's personality. Some of the things you can create are extremely useful. However, as the game's combat relies on pattern recognition and quick reactions, you may find yourself ignoring consumables in favor of honing your dodging skills.
For this reason, Beast Blood is an excellent commodity. It's not hard to come by, but it's also not really useful in the end products it's used to make. Not much can be gained from 50 runes, but at least it beats carrying around a quantity of genuine blood that you won't use.
