As Zagreus journeys through the Underworld, he will encounter different Artifacts that will greatly impact each and every playthrough. These items can either be permanent to be used after each encounter or temporary for use only during the specific run you are doing.
So, we came up with a guide detailing every Artifact and how it benefits Zagreus.
