Abyss Artifacts allow you to improve the skills of all playable characters in Crimson Desert, but they come in limited amounts. However, the current build seems to have a glitch that allows you to collect as many Abyss Artifacts as required.
While the process is grindy and requires a bit of time (circa five minutes for one), it can be a great way to power up your characters early in the game. While I am unsure when this method will get patched out, it still works as of writing.
