If you are fond of exploring the different realms in God of war Ragnarok, you will eventually find some artefacts. These may get you quite excited due to the purple marker on the ground only to find it is nothing that is going to directly make you stronger.
If you have paid a visit to the blacksmith for some upgrades, you will see that it is possible to sell these artifacts in bulk, often for a large amount of hacksilver. The question that anyone who has ever played an RPG before is whether there is any reason to keep these artifacts? Will you get to a point in the game later on where you regret selling them because they are useful for something else?
The good news is that these artifacts are of no use for anything other than selling and collecting. Selling them does not remove them from your collection either so you can sell these artifacts as soon as you get them. The hacksilver you get from them is much better in your pocket and spent on armor upgrades.
