Genshin Impact Artifact Guide 2026: Stats, Sets and How to Farm Efficiently

Artifacts are the equipment system in Genshin Impact that determines your actual damage output, making them far more impactful than character levels or talent upgrades. This guide covers the five artifact slots, the critical distinction between fixed and variable main stats, the substat roll system, and the honest farming reality built around HoYoverse’s Resin economy—written to stay accurate across banner cycles into Version 7.0.

Artifacts are equipment pieces that add stats and set bonuses to a character, with every character able to equip five artifacts. Each character has five artifact slots: Flower of Life, Plume of Death, Sands of Eon, Goblet of Eonothem, and Circlet of Logos. Flower of Life always provides flat HP as its main stat, while Plume of Death always provides flat ATK—the other three slots offer variable main stats that define your build. Main stat correctness is roughly 80% of build quality, substats are 15%, and set bonus is 5%, which means picking the right main stats on Sands, Goblet, and Circlet matters far more than chasing perfect substats. Artifacts are the true endgame grind in Genshin Impact, dwarfing the effort needed for character ascension or talent books, and you’ll spend more time in HoYoverse’s artifact domains than anywhere else once you hit Adventure Rank 45.

Main stats are your fixed powerhouses—Flower’s flat HP caps at 4,780 for a maxed 5-star, and Plume’s flat ATK reaches 311. These two slots have zero decision-making; their main stats are locked by design. The real choices happen on the remaining three slots: Sands, Goblet, and Circlet. Sands options include ATK% at 46.6% for general damage dealers, ER% if your bursts need reliable uptime, EM stacking to 187 for reaction teams, or HP%/DEF% at 58.3% for scaling characters. Goblets are where you lock in your damage type—Elemental DMG% (Pyro, Hydro, Cryo, etc.) for most DPS builds, or ATK%/HP%/DEF% for specific scalers. Circlets offer CRIT Rate at 31.1% or CRIT DMG at 62.2%, making this the most contested slot for damage-focused builds.

A 4-star with the correct main stat and 2-3 good substats beats a 5-star with wrong main stat every time. Do not wait for a full 5-star set before using a character—swap in correct main-stat pieces immediately and upgrade them as you farm.

Every artifact has one main stat and up to four substats; by leveling up artifacts you enhance the main stat and unlock new substats every four levels, and if all four substats are unlocked, leveling up the artifact will enhance a random substat. 5-star artifacts cap at level 20, giving you five total substat rolls: one at +4, +8, +12, +16, and +20. You get an 80% chance for 4 substats rather than 3 at AR45+ domains, which means most of your endgame pieces start with four lines and every roll goes into upgrading an existing stat rather than unlocking a new one.

Substat priority is straightforward for most builds: CRIT Rate and CRIT DMG are the universal S-tier stats, followed by ATK%, Energy Recharge, and Elemental Mastery depending on role. Flat HP, flat DEF, and flat ATK are nearly worthless for endgame builds because percentage scaling vastly outpaces flat additions at level 90. The dream artifact—often called “quad crit”—drops with CRIT Rate, CRIT DMG, ATK%, and ER or EM, then rolls multiple times into the crit lines.

Total cost to level an artifact from +0 to +20 is roughly 270,000 mora and 150k artifact XP per piece. Do not burn resources leveling bad pieces; if an artifact rolls into flat DEF twice by +8, feed it to something better. The sunk cost of a few levels is nothing compared to the mora you’ll waste taking trash to +20.

Artifacts drop from Domains of Blessing, with each domain offering two specific artifact sets; spending 20 resin (or one Condensed Resin for a double run) rewards artifacts at the domain’s level, making this your primary repeatable artifact source. Adventure Rank 45 is the threshold where Level III Domains guarantee at least one 5-star artifact per 20-Resin run, making farming 71% more efficient than pre-AR45 attempts. Do not farm artifacts seriously before AR45—the drop rates are miserable and you’ll waste weeks of resin on 4-star pieces you’ll immediately replace.

Beyond domains, you can obtain artifacts from the Artifact Strongbox system unlocked at Adventure Rank 45, where every three 5-Star Artifacts sacrificed create one Artifact Strongbox containing a random artifact from the selected set. The Artifact Transmuter gadget (released in Version 5.0) lets you create an artifact with a specific set, piece, main stat—except Head and Feather which are fixed—and up to two defined substats, though the remaining substats and all upgrade rolls remain random. The Transmuter requires Sanctifying Elixir extracted from upgraded artifacts, making it a long-term optimization tool rather than a shortcut.

For new players working through the early progression curve, focus on advancing your Adventure Rank and clearing story content before committing to artifact farming. The system is designed to be the final layer of optimization, not something you tackle while leveling your first team.

Artifact sets grant bonuses when you equip multiple pieces from the same set: a 2-piece bonus and a 4-piece bonus. The decision between running a full 4-piece set versus mixing two 2-piece sets depends entirely on whether the 4-piece effect is crucial to your character’s kit.

When to Run 4-Piece Sets

Choose a 4-piece set when the bonus directly amplifies your primary damage pattern or solves a critical resource problem. Reaction-focused DPS characters often need their 4-piece bonus to reach competitive damage—think Viridescent Venerer for Anemo supports shredding resistance, or Emblem of Severed Fate for burst-reliant sub-DPS who convert Energy Recharge into damage. If the 4-piece effect saves you a full rotation or enables a specific combo, farm the full set.

When to Mix 2-Piece + 2-Piece

Mix two 2-piece sets when the 4-piece bonuses available are marginal or situational. Many ATK-scaling DPS characters function perfectly fine with combinations like 2-piece ATK%+18% and 2-piece Elemental DMG%+15%, which offer consistent unconditional bonuses. This approach also lets you use your best-rolled off-pieces without forcing a mediocre on-set Goblet or Circlet just to complete the 4-piece.

Off-Piece Strategy

Because Goblets and Circlets have the hardest main-stat RNG (Elemental DMG% Goblets are rare, and the CRIT Rate vs CRIT DMG decision is binary), most players run their best off-set piece in one of these slots. Farm your 4-piece using Flower, Plume, Sands, and one flex slot, then plug your best off-set Goblet or Circlet into the final slot. This flexibility dramatically reduces the grind.

The artifact system is Genshin‘s most brutal RNG layer: 160 resin per day, no stamina pots from gacha, and one DEF% Circlet means you’re out—every dead run is resin you can’t get back. Resin caps at 160, so unused points go to waste (the actual cap is 200 including overflow, but natural regeneration stops at 160). Resin is the single most precious resource in the game, and artifact farming consumes it faster than any other activity because the RNG layers stack: correct set, correct slot, correct main stat, useful substats, and favorable upgrade rolls.

Daily Resin regenerates 180 over 24 hours—that’s 9 domain runs at 20 Resin each, yielding a minimum of 63 five-star artifacts weekly using all 1,260 total Resin. Sounds generous until you realize that getting a single on-set Elemental DMG% Goblet with two crit substats can take months. Artifact farming will never be perfectly efficient—randomness is baked into the system, but efficiency isn’t about eliminating luck; it’s about minimizing loss and maximizing returns within its constraints.

Myth: You Need Perfect Substats to Clear Content

The correct main stat on the correct set with 2–3 decent substats is enough to 36-star Abyss; everything beyond that is speedrunner territory. Players obsess over quad-crit god rolls while wearing the wrong main stat, then wonder why their damage is low. Get your main stats right first, accept pieces with two useful substats, and move on. Perfect artifacts are a luxury, not a requirement.

Myth: Set Bonuses Matter More Than Main Stats

A correct main stat with weak substats is often stronger than a wrong main stat with great substats, and this matters most on Sands, Goblets, and Circlets because their main stats are random. Wearing an off-set Goblet with the correct Elemental DMG% main stat will always outperform an on-set Goblet with ATK% just to complete your 4-piece bonus. Break the set if you have to—the main stat is more valuable.

Myth: You Should Farm Artifacts Before AR45

Before AR45 you’re looking at a measly 30-50% chance for 5-star artifacts, which means burning 40-60 Resin just for what becomes a guaranteed drop later. Every resin spent in lower-level domains is resin you’ll wish you saved. Use whatever artifacts you find from bosses and quests while leveling, then commit to serious farming only after AR45 unlocks.
