Crimson Desert does not feature a standard leveling system, complete with XP and skills you unlock through levels. Instead, it uses Abyss Artifacts, expendable currency items that are used to upgrade skill trees (Stamina, Spirit, and Health) or unlock and upgrade specific abilities within them.
They are obtained in various ways, but Sealed Abyss Artifacts can be a tremendous source of much-needed Abyss Artifacts, since they are also required to refine weapons and armor past a certain point, leading to a relative drought of Abyss Artifacts at some points in the game.
