Flame Altar and Strengthening the Flame
How the Flame Altar claims a base, how altar size upgrades work, and what Strengthening the Flame gives you at each level.
Last updated: 2026-10-16
The Flame Altar is the workshop that claims a base. Anything built, placed, or terraformed inside its boundary is permanent; changes made outside it reset after 30 minutes or a server restart. It is crafted from 5 of any stone via Manual Crafting once you accept the Claim a Spot for Your Base quest.
What the Flame Altar does
- Claims a permanent building area and allows terrain reshaping inside it.
- Lets you spend materials on Strengthening the Flame, Embervale's global upgrade track.
- Lets you reset your skill tree for 1 Rune per spent skill point.
- Acts as a fast travel point and a heat source for Rested buffs.
- In 1.0, Flame 10 raises the Altar limit to 15 before Cinder's Cradle; Flame 11 raises it to 16 after the final boss and lets Altars push back the Shroud.
Altar size upgrades
| Altar level | Max area | Materials | Required Flame level |
|---|---|---|---|
| 1 | 40×40×40 | None | 1 |
| 2 | 80×80×80 | 1 Shroud Core | 1 |
| 3 | 120×120×120 | 5 Shroud Core | 2 |
| 4 | 160×160×160 | 5 Shroud Nexus | 3 |
Strengthening the Flame
Strengthening the Flame is a separate, global upgrade track shared by every altar you own. The Early Access levels 2–9 reference describes these benefits (do not extrapolate to levels 10–11):
- Increases every primary attribute by 1 (from Flame level 2 onward).
- Adds 1 minute of maximum Shroud time.
- Raises your Shroud Passage Level, opening previously deadly Shroud.
The Early Access recipes used a boss head from the corresponding boss guide plus a bundle of regional materials, so plan a farming pass through the matching region before attempting to upgrade. The Flame level itself never decreases, even if every altar is extinguished.
Flame 6–9 recipes changed in 1.0; old costs are no longer valid. Flame 10–11 materials and Shroud times: Not yet verified for 1.0.

Removing an altar
Deactivating a Flame Altar starts a 30-second cancellable timer. Once it disappears, anything built inside its old boundary stays in place until the area resets (30 minutes, or a server restart) unless you place a new altar first. A replacement altar does not inherit its predecessor's size upgrades.
