Artifacts are the “equips” of Genshin Impact, and can massively improve the performance of a certain character based on their effects. The categories are a tad odd, it isn’t like the head, chest, arms, waist, and legs system most games use. Instead, it’s broken down into Flower of Life, Plume of Death, Sands of Eon, Goblet of Eonothem, and Circlet of Logos. If that sounds overly complex it is, but put simply it’s a flower, a feather, a clock/hourglass, a cup, and a headpiece. And, each of them can have a variety of different states, one main one, and up to four sub-stats depending on the item level.
What players should know is that the main stat can change between two different versions of the same item, and the 4 sub-stats are randomized for every 4 artifact levels. So, if an Artifact doesn’t have the stat a player would like, simply look for more of that same Artifact and level it up again. It’s small, but things like this are what eventually lead to building a super overpowered team.
