Crimson Desert Sealed Abyss Artifact locations and how they work
Finding Sealed Abyss Artifact locations in Crimson Desert and completing their challenges is one of the best ways to get Faded Abyss Artifacts, which you use to respec your character. It's also your primary way of getting Abyss Gears—rune-like items that you can slot into weapons and armour to provide them bonuses.
You may have already acquired an item with Abyss Cores inset such as the Sword of the Lord you get from the Hornsplitter boss. If you examine it, you can see the cores and the effects they have on its stats.
