Artefatos Genshin Impact

Artifacts are a character's 5-slot equipment: Flower of Life, Plume of Death, Sands of Eon, Goblet of Eonothem, and Circlet of Logos. As of patch 6.7 / Luna VIII, there are roughly 62 sets in total (46 5-star, 13 4-star, 3 3-star — the exact count varies slightly by source depending on whether 4-star/3-star sets are counted), and each Domain of Blessing drops 2 different sets.

Every set has two effect tiers: wearing 2 of 4 pieces from the same set unlocks the 2-piece bonus (usually a flat % stat boost), while wearing all 4 of 4 unlocks a stronger 4-piece bonus that usually comes with its own trigger condition — always read the exact wording before committing. You don't have to run a full 4-piece set: mixing 2+2 (2 pieces from Set A + 2 from Set B) is often stronger than forcing a 4-piece set built from weak-substat pieces. An "off-piece 4+1" setup — 4 pieces of your main set plus 1 loose piece from another set purely for a better main stat — is also a valid choice when the fifth slot won't roll the right main stat in your main set.

Flower of Life and Plume of Death always carry fixed flat stats (HP and ATK) — nothing to choose there. Only the remaining 3 slots roll a random main stat, and getting the right one matters more than set bonuses or perfect substats.

General rule: the correct main stat always beats the wrong one regardless of rarity — a correctly-rolled 4-star piece outperforms a 5-star piece with the wrong main stat.

Artifacts have 10 possible substats: flat HP/ATK/DEF, HP%/ATK%/DEF%, Crit Rate (CR), Crit DMG (CD), Elemental Mastery (EM), and Energy Recharge (ER). For most DPS teams, CR and CD are the most valuable substats because they raise average damage on every single hit, followed by ATK%, while EM/ER matter depending on the role (EM for reaction-focused teams, ER for characters that need fast energy recharge); the three flat stats (flat HP/ATK/DEF) are generally treated as "junk" rolls for most characters.

A quick way to grade a single piece is Crit Value (CV) = Crit DMG + Crit Rate × 2, since the ideal CR:CD ratio is 1:2 (e.g. 5% CR is worth roughly the same as 10% CD). CV is only a fast way to compare individual pieces to each other — it doesn't replace comparing actual damage output for a full loadout with a proper build calculator.

Artifacts mostly drop from Domains of Blessing — each domain always drops the same 2 sets, and every run costs Original Resin. Adventure Rank (AR) decides drop quality: skip domains before AR30 since rewards are still low, AR30-44 is only for learning/experimenting, and from AR45 onward you should farm seriously, since the domain opens its highest difficulty and guarantees at least 1 5-star piece per 20 Resin.

The Strongbox lets you combine 3 5-star pieces from the same domain into 1 random piece targeted at the set you actually want, useful when that domain drops 2 sets but you only need one of them; feeding the resulting piece back into the Strongbox again pushes the odds of hitting your target set toward roughly 2:1 over time. The newer Reshaping/Transmuter system also lets you change the main stat or a substat on an already-finished piece, cutting down on having to farm from scratch after rolling the wrong main stat.

Some sets get used across so many different characters that they're always worth farming early: Emblem of Severed Fate and Noblesse Oblige are common for support/sub-DPS characters buffing skill damage, while Marechaussee Hunter and Golden Troupe fit a wide range of normal-attack and skill-based DPS. For elemental teams, Viridescent Venerer is still a top pick for Anemo characters, and Deepwood Memories is preferred for Dendro teams that need to shred a target's Dendro resistance.

Patch 6.7 / Luna VIII adds a new set, Disenchantment in Deep Shadow (2-piece: ATK +18%; 4-piece: boosts Superconduct DMG and Crit Rate when hitting an enemy afflicted with Superconduct — the exact 4-piece numbers should be double-checked once the game officially publishes them), while 6.6 brought Gift from Heaven (2-piece: ER +20%; 4-piece: boosts the whole party's Elemental DMG, with a bigger boost if the team has more than one character from the same newer character group).

Resin-saving tips: always prioritize the correct main stat first, and don't force a 4-piece set out of weak-substat pieces — a 2+2 split is often better value; and once a character is "good enough" (correct main stats, a reasonable CR:CD ratio, enough Energy Recharge for the rotation), stop farming for them and put your Resin toward another character who's still missing the basics instead of chasing one more near-perfect piece.
