Where to farm Heart of the Furnace: the Inverted Glacier domain
By DayOneFix Editorial · August 25, 2026
You have the character who wants the set — now you need the domain. Heart of the Furnace (and its sibling set Scarlet Proof) drops from one place: Domain of Blessing [Inverted Glacier], in Everfrozen Earth, Snezhnaya. Here is the fastest way in, and the farming decisions that actually matter once you are there.
Where the domain is
- Region: Everfrozen Earth, Snezhnaya — south of Morepesok
- Fastest route: teleport to the Rankova Zorya train station waypoint, then head northeast across the ice until the domain entrance appears
- Unlock: reachable and unlockable early in the 7.0 Archon Quest — you do not need to finish the Snezhnaya story to start farming
What drops there
| Set | What it does | Who farms it |
|---|---|---|
| Heart of the Furnace | +50% Stellar Glimmer reaction DMG to the whole party, works off-field, one wearer only | Odette first; any Stellar team needs exactly one carrier |
| Scarlet Proof | +16% CRIT Rate / +40% Stellar Swirl DMG to the wearer | Stellar Swirl on-field carries |
Both 7.0 sets come from the same domain at the top difficulty tier — one farm feeds both. Lower tiers list legacy filler (The Exile, Brave Heart); there is no reason to run those. Like every artifact domain, Inverted Glacier is open every day — no weekday rotation — at the standard 20 Original Resin per clear.
The full set breakdown — official effects, piece names, the one-wearer rule and the Alyosha stacking trap — is on the 7.0 artifact sets page.
The Abyss shortcut
From this Spiral Abyss cycle onward, the Ley Line rewards on Floors 9–12 hand out these two sets in place of Disenchantment in Deep Shadow and Celestial Gift (official 7.0 update notes). If you clear Abyss anyway, that is free progress on the same farm — do it before spending resin.
When to stop
- One good Furnace 4-piece is the whole job. The party bonus does not stack, so a second Furnace wearer adds nothing — after the first solid set, switch the resin to Scarlet Proof or talents.
- Off-pieces are legal. The 2-piece bonuses matter less than main stats: ATK / ATK / crit for the Furnace carrier beats a “perfect” 4-piece with a flat-HP circlet.
- If your team cannot convert reactions — no Odette, no Cryo Traveler — neither set does anything yet. Unlock the Traveler first: how to unlock her and her constellations.
