Artifacts are rewards for winning Underworld Encounters which either benefit Zagreus 's current escape attempt or can be spent to obtain permanent benefits on future attempts.
Currency Artifacts[edit | edit source]
These can be spent on permanent upgrades and are obtained from standard Encounters. These resources persist after a run (i.e., they are not lost whether or not Zagreus succeeded in escaping) and can be used back in the House of Hades.
