Artifacts are character equipment in Genshin Impact and every character can equip up to five artifacts in five different positions such as Flower of Life, Plume of Death, Sands of Eon, Goblet of Eonothem, and Circlet of Logos.
Artifacts have a rarity from one star to five stars. Each rarity has its own maximum levels and players are able to level up artifacts using other artifacts.
Each type of artifact has a main stat and a maximum of four sub stats. When an artifact reaches a multiplier of 4 levels and if that artifact doesn’t already have 4 sub stats, it will randomly choose an additional sub stat and added it to the artifact. If the artifact already has four sub stats, one of those four will be randomly chosen and get a power-up.
Regardless of rarity, when equipping two or four artifacts from the same kind of artifacts, players will receive the set bonus and these bonuses are different for every set.
