There are 5 types of Artifacts that can be equipped: Flower of Life, Plume of Death, Sands of Eon, Goblet of Eonothem, and Circlet of Logos. Only one of each type can be equipped on a character at a time.
All Artifacts have a main affix, commonly known as main stat, along with up to 4 minor affixes, commonly known as sub stats or secondary stats. These affixes can greatly increase the character's strength in combat. Certain artifact types, such as the Flower of Life and Plume of Death, can only come with a specific main stat, while other types can come with one of many main stats.
How to Obtain
Artifacts can be obtained by exploring Teyvat and finding Investigation Spots, Chests, defeating Elite Enemies and Bosses, claiming rewards from Petrified Trees in Domains of Blessing, and acquiring Chamber Bounties in the Spiral Abyss.
At the highest Domain level, Artifact Domains averages at 1 5-Star featured artifact and 1.5 4-Star featured artifacts. Featured artifacts each have 50% to be either of the two types.
A maximum of 1,000 Artifacts can be in a player's Inventory at a time. If the player tries to collect another Artifact, a special notice will appear on-screen.
1 point of EXP costs Mora ×1 except when recycling an already-leveled artifact.
Upgrading a full set of 5★ artifacts to level 20 will cost 270,475 × 5 = 1,352,375 Artifact EXP & Mora.
1-Star to 4-Star Artifacts can be destroyed for Mora, and up to 100 Artifacts can be destroyed at a time. The Artifact must be at Level 0 (+0) with 0 EXP. The Mora received is 420/840/1260/2520 depending on the rarity, which is equal to the Mora it would cost to use the Artifact as Artifact EXP.
Artifact Sets are different kinds of artifacts that have different Set Bonuses depending on how many are of that set are equipped on a character. Currently, there are 36 Artifact Sets:
Each artifact has one main stat, determined by the artifact's type/slot. Its value at each level is determined by the stat and the artifact's rarity. Main stats include HP, HP%, ATK, ATK%, DEF%, Elemental Mastery, Energy Recharge%, Elemental Damage% for one of the 6 playable Elements, Physical Damage%, Crit Rate%, Crit DMG%, and Healing Bonus, but not all stats are available for all artifacts.
Along with the main stat, artifacts have up to 4 sub-stats that are all different from the main stat. For every 4 levels that an artifact gains, an additional sub-stat is added unless the artifact already has 4 sub-stats, in which case a random sub-stat is upgraded. Sub-stats include HP, HP%, ATK, ATK%, DEF, DEF%, Elemental Mastery, Energy Recharge%, Crit Rate%, and Crit DMG%.
