Genshin Impact 7.0 Artifact Sets Beta Guide: Scarlet Proof, Heart of the Furnace, Best Users, and Farming Value
Genshin Impact Version 7.0 beta data points to two Snezhnaya artifact sets built around ATK and Stellar Reactions. This guide separates current test-server effects from confirmed live information, compares Scarlet Proof with Heart of the Furnace, identifies the account profiles most likely to benefit, and explains how to prepare Resin without committing to unfinished numbers.
Two new artifact sets can reshape more accounts than one new character. A character banner affects the players who pull it; a strong domain can become a farming destination for months. Version 7.0 beta data describes Scarlet Proof and Heart of the Furnace as two ATK-based sets connected to Stellar Superconduct and Stellar Swirl, making the first Snezhnaya artifact domain unusually focused on the new reaction family.
Everything in this guide is based on beta and datamined information available before Version 7.0 launches on August 12, 2026. Names, percentages, duration, stack rules, trigger wording, and eligible reactions may change. The purpose is to understand the design direction and prepare flexible resources, not to promise final best-in-slot rankings.
Read the Evidence Label Before the Set Bonus
The existence of two new sets is supported by current beta databases, but beta text is not a live-server contract. A small wording change can alter who triggers a set, whether it works from off field, whether multiple copies stack, and how long the buff survives a rotation.
The translated English names also vary between databases. Scarlet Proof is comparatively stable in current reporting, while the second set is commonly rendered as Heart of the Furnace. Official English and Chinese names should be taken from the Version 7.0 client or final equipment preview.
Treat every current recommendation as conditional. The sets may preserve their overall identities while changing enough numbers to move individual characters from excellent users to merely acceptable users.
The Two-Set Snapshot
Both leaked sets currently use an 18% ATK two-piece bonus. That familiar baseline makes them easy temporary combinations for ATK-scaling characters, but the four-piece effects target different jobs.
Beta set | Reported two-piece effect | Reported four-piece identity | Likely job |
|---|---|---|---|
Scarlet Proof | ATK +18% | Trigger Stellar Superconduct or Stellar Swirl to gain personal ATK and support nearby allies' Stellar damage | Reaction support or hybrid damage dealer |
Heart of the Furnace | ATK +18% | Trigger Stellar Swirl to gain CRIT Rate and increase Stellar Swirl damage | On-field or direct Stellar Swirl damage dealer |
The critical question is not which set has the larger isolated number. It is whether the team's reaction ownership matches the trigger. A powerful effect on the wrong character is still inactive.
Scarlet Proof Is a Team Set First
Scarlet Proof currently appears to reward a character for triggering Stellar Superconduct or Stellar Swirl, or for dealing direct damage associated with those reactions. The reported effect grants ATK to the wearer and increases Stellar Superconduct and Stellar Swirl damage for nearby party members. Beta text also indicates that the effect can be triggered while the wearer is off field.
That combination gives Scarlet Proof three possible users. The first is an off-field applicator who consistently participates in the required reaction. The second is a support whose personal damage still benefits from ATK. The third is a hybrid character who triggers the reaction, buffs the team, and then leaves the field.
The off-field clause is especially valuable. It allows the set to support a main damage dealer without forcing the wearer to interrupt the rotation. However, players must verify the final trigger frequency. If one reaction refreshes the entire duration, a low-field-time support can maintain the buff easily. If the effect uses independent stacks or stricter ownership, team construction becomes more demanding.
Scarlet Proof should not automatically replace every support set. Viridescent Venerer, Noblesse Oblige, Scroll of the Hero of Cinder City, Instructor, and other support options solve different problems. Resistance reduction, Energy, Elemental Mastery, or a broad damage bonus may remain stronger than a reaction-specific buff on teams that only produce part of their damage through Stellar reactions.
Heart of the Furnace Is the Carry Set
Heart of the Furnace is narrower and easier to understand. Current beta data links its four-piece effect to triggering Stellar Swirl, gaining CRIT Rate, and increasing Stellar Swirl damage. It therefore targets a character who owns meaningful direct Stellar Swirl damage rather than a support who happens to cause the reaction occasionally.
This set becomes attractive when three conditions are true. The wearer triggers Stellar Swirl reliably, the character's important damage can use the reported CRIT benefit, and the team keeps the effect active during the main damage window. If any one condition fails, a general damage set may produce more consistent results.
The 18% ATK two-piece bonus also matters. A character whose Stellar damage scales from a different statistic may value the four-piece effect but waste part of the set. Conversely, a conventional ATK-scaling Anemo or Cryo character may enjoy the two-piece bonus without being able to activate the full effect.
Do not build a critical ratio around the leaked set bonus until the final value and uptime are known. A beta CRIT Rate bonus can be reduced, moved to a stack system, or attached to a shorter duration. Keep alternative circlets and weapons so the build does not collapse if the final bonus changes.
Which Characters Look Most Relevant
Odette is the obvious character to watch because her official Cryo and Stellar Linchpin identity connects directly with Version 7.0's new reaction direction. That does not prove which set is best. The answer depends on whether she owns Stellar Swirl damage, enables another character, spends time on field, and values ATK in the final kit.
Sandrone and Yumemizuki Mizuki also deserve attention because beta adjustments reportedly give them more direct interaction with Stellar Swirl. If those changes reach the live client, Heart of the Furnace may offer a more specialized damage route, while Scarlet Proof may support teams where another unit owns the largest Stellar hits.
Kazuha, Venti, Sucrose, and other Anemo characters appear in compatibility discussions, but compatibility is not the same as best-in-slot status. If a talent is only updated to recognize Stellar Swirl, that character may still prefer Viridescent Venerer for resistance reduction or an Energy-focused setup for rotation stability.
Cryo and Electro characters participating in Stellar Superconduct may consider Scarlet Proof if they can trigger it from off field. The final ownership rules are essential. A character who applies an element but does not legally own the reaction may fail to activate the set even if the reaction appears on screen.
A User-Archetype Test
Instead of assigning a final character tier list before launch, test each candidate against four questions.
First, can the wearer trigger the required reaction without changing the team's natural rotation? A set that needs an awkward extra attack or delayed swap carries a hidden cost.
Second, does the wearer use the two-piece ATK bonus? Partial value is acceptable, but it lowers the advantage over general alternatives.
Third, does the four-piece effect improve the wearer, the main carry, or both? Scarlet Proof gains value when the support and carry benefit simultaneously. Heart of the Furnace gains value when the wearer contributes a large share of direct Stellar Swirl damage.
Fourth, what is lost by leaving the old set? Compare resistance reduction, Energy, damage bonuses, Elemental Mastery, and substat quality. The new set must beat the complete old package, not just its four-piece sentence.
Main Stats and Substats
ATK Sands, elemental or reaction-relevant Goblet, and CRIT Circlet will be a common starting point for ATK-scaling damage dealers. That is only a starting point. Stellar reaction formulas may increase the value of Elemental Mastery, while burst-dependent characters may still require Energy Recharge Sands or substantial Energy substats.
Do not force a damage main stat if the rotation fails. Missing one Elemental Burst every second cycle is usually a larger loss than exchanging a few offensive rolls for Energy Recharge.
For Scarlet Proof supports, prioritize the statistic that keeps the trigger reliable. That may be Energy Recharge, Elemental Mastery, ATK, or enough CRIT Rate for a weapon passive. A support set is not successful merely because its wearer has attractive critical numbers.
For Heart of the Furnace, calculate the final critical ratio with the live four-piece bonus active. If the bonus has limited uptime, test the character both inside and outside the window. A build that overcaps CRIT Rate during the buff and feels weak outside it wastes resources.
Should You Save Fragile Resin?
Saving some Fragile Resin is reasonable if Odette or another Stellar-focused character is a firm build target. Saving every Fragile Resin is unnecessary. The first week is when set effects, reaction ownership, and rotation requirements are least understood.
A balanced plan is to preserve enough Resin for several domain sessions, while keeping Mora, experience materials, weapon materials, and boss costs covered. A new artifact set cannot compensate for an underleveled character, weapon, or core talent.
Use early Resin to obtain functional main stats, not perfect pieces. Once a four-piece set can be tested, compare it with the existing build in repeatable content. Only then decide whether the domain deserves a long farming commitment.
Players preparing account currency for Version 7.0 can compare options through Topuplist and the dedicated Genshin Impact top-up page. Keep artifact spending and banner spending separate: obtaining a character does not guarantee the Resin needed to finish a new set immediately.
Domain Value Depends on Both Sets
A domain is efficient when both sets have realistic users. Scarlet Proof and Heart of the Furnace share an ecosystem, which can make the domain valuable for players building several Stellar teams. One set may serve the support while the other serves the direct damage dealer.
The same domain can be poor for an account with no intention of using Stellar Superconduct or Stellar Swirl. In that case, the 18% ATK two-piece bonuses are convenient but not enough to justify months of farming over a broadly useful domain.
Evaluate the account, not the hype. Count the characters that can use a full four-piece effect, the characters that only want a two-piece mix, and the supports that would give up a better utility set. A domain with one excellent user and five speculative users is not automatically efficient.
What Could Still Change Before Release
Beta balance changes may alter percentages, durations, trigger cooldowns, stacking limits, off-field activation, or eligible reactions. Names and descriptions may also receive localization changes. The most dangerous assumption is that a leaked set will preserve both its number and its exact interaction with every existing talent.
Version iterations matter. A V1 screenshot should not override a later V3 or V4 database entry. When sources disagree, prefer the newest identifiable build and label the conflict rather than combining the best parts of both versions.
After August 12, open the artifact archive in the live client and read the final text. Then test the set with damage numbers and buff indicators. That live evidence replaces every pre-release recommendation.
A Sensible Launch Plan
Before launch, lock strong ATK, Elemental Mastery, Energy Recharge, elemental damage, and CRIT pieces from existing sets. Save a moderate Resin reserve and enough artifact experience to raise promising pieces gradually.
During the first three days, obtain functional pieces only if the domain is accessible and relevant. Verify who triggers the reaction, whether Scarlet Proof activates off field, and whether Heart of the Furnace's critical benefit remains active through the main combo.
During the first two weeks, compare complete rotations rather than one screenshot hit. If the new build saves time, improves consistency, or strengthens both sides of endgame content, continue farming. If it only raises an isolated number while creating Energy or support problems, return to the established set and revisit the domain later.
The best pre-release decision is not choosing a winner between Scarlet Proof and Heart of the Furnace. It is entering Version 7.0 with enough flexible resources to let the live game answer the question.
FAQ
Are Scarlet Proof and Heart of the Furnace officially confirmed names?
They are names used in current beta and datamined reporting. Final English and localized names should be verified in the Version 7.0 live client.
How many new artifact sets are reported for Version 7.0?
Current beta data lists two sets. Both reportedly have an 18% ATK two-piece bonus, while their four-piece effects focus on Stellar reaction teams.
Is Scarlet Proof a support set?
Its reported personal ATK and team Stellar damage bonuses, including off-field activation, make it look support-oriented. Final trigger and stacking rules will determine its actual role.
Is Heart of the Furnace only for Odette?
No exclusive restriction has been reported. Any character that reliably triggers and deals significant Stellar Swirl damage may be a candidate, but final testing is required.
Can I prepare Genshin Impact currency while waiting for final artifact data?
Yes. Confirm the target banner and server first, then review options through Topuplist's official site and the Genshin Impact recharge page. Keep the purchase budget separate from the Resin and material plan.
