Enshrouded 1.0 has 11 Flame levels, so 10 upgrades. Together they cost 266 Spark, a boss trophy for every upgrade after the first, and five biome materials per step. You also need up to 18 survivors with beds. Each level adds 1 minute of Shroud time (5:00 at Flame 1, 15:00 at Flame 11), raises your Flame Altar limit (2 up to 16), gives +1 to all core attributes, and unlocks the next tier’s armor sets. Flame 10 opens Cinder’s Cradle. Flame 11 needs the final boss and lets altars push back the Shroud.

1.0 changes: Keen lowered the material amounts for Flame 6 to 9 and replaced Electric Organs and Poison Stings with more common resources. If a guide lists Electric Organs for Flame 7, it’s from Early Access. Fell Vultures also drop more Enshrouded Vulture Talons now, which makes Flame 6 quicker.
Where to find each material is in the materials finder. Searching “Flame 7” there lists only that step’s materials.
What each level unlocks
| Flame | Shroud time | Altar limit | Water sources | Attribute bonus | Shroud region opened |
|---|---|---|---|---|---|
| 1 | 5:00 | 2 | 1 | 0 | Start |
| 2 | 6:00 | 4 | 1 | +1 | Springlands |
| 3 | 7:00 | 6 | 1 | +2 | Revelwood |
| 4 | 8:00 | 8 | 5 | +3 | Nomad Highlands |
| 5 | 9:00 | 10 | 10 | +4 | Kindlewastes |
| 6 | 10:00 | 11 | 20 | +5 | Albaneve Summits |
| 7 | 11:00 | 12 | 30 | +6 | Albaneve Summits |
| 8 | 12:00 | 13 | 40 | +7 | Veilwater Basin |
| 9 | 13:00 | 14 | 50 | +8 | Veilwater Basin |
| 10 | 14:00 | 15 | 50 | +9 (unconfirmed) | Cinder’s Cradle |
| 11 | 15:00 | 16 | 50 | +10 (unconfirmed) | Altars push back the Shroud |
How sure we are of each column:
- Altar limit: 1.0-confirmed. Keen’s changelog says Flame 10 raises the limit to 15 and Flame 11 to 16. PinDrop’s file data has the full column, and it matches. The Enshrouded Wiki’s Flame Altar page still lists older Early Access limits (7 at Flame 4, 13 at Flame 10), so don’t use those.
- Shroud time: from PinDrop’s 1.0 balancing table (checked against the files). The wiki’s values for Flame 2 to 9 match.
- Attribute bonus: the wiki lists +1 per level from Flame 2 to 9. Allthings.how describes it as “+1 to all core attributes per level”. We extended the same pattern to Flame 10 and 11, but no source gives those two values directly.
- Shroud Passage level: equal to your Flame level (wiki, allthings.how). It controls which Shroud barriers you can pass.
- Armor: 1.0-confirmed. Each Flame upgrade unlocks the next tier’s armor sets automatically, so you can’t miss them by skipping a material.
The Flame level is global and never goes down, even if every altar goes out (wiki).
Flame 11: pushing back the Shroud
At Flame 11, Flame Altars can push back the Shroud (Keen 1.0 changelog). Hosts can lower the required level in the world settings. PinDrop lists the setting as “Required Flame level to enable placing Flame Altars into the Shroud”, default 11. The Flame 11 upgrade itself needs both of Vorgoth’s drops. See the Vorgoth boss guide.
Flame level vs altar level
These are two separate upgrade tracks, and guides often mix them up:
- Strengthening the Flame (this page) raises your global level with Spark, materials and trophies.
- Upgrading an altar makes that one base bigger. It uses Shroud Cores and Shroud Nexus.
| Altar level | Build zone | Cost to reach |
|---|---|---|
| 1 | 40 m | 1 Shroud Core (claim) |
| 2 | 80 m | 1 Shroud Core |
| 3 | 120 m | 5 Shroud Core |
| 4 | 160 m | 5 Shroud Nexus |
That’s 7 Shroud Cores and 5 Shroud Nexus per altar (PinDrop, 1.0 files). Altar level 4 is the cap in 1.0.
Getting the Spark
You need 266 Spark in total, and the last three upgrades take 130 of it. Spark comes from Flame Shrines and Sanctums, which show as golden flames on the map, and from the Hidden Flame Shrine quest (allthings.how). Pick them up as you explore each region, so you don’t have to go back for them when you reach Flame 9.
Survivors
Survivors count toward the requirement only once each has a bed in a sheltered room (allthings.how). Flame 10 needs 16 and Flame 11 needs 18. If the upgrade button is greyed out and you have the materials, check that every rescued survivor has been assigned a bed. Loraine Crim, the Ancient Researcher, is a new 1.0 survivor you summon in Cinder’s Cradle, and counts toward the 18 for Flame 11 once given a bed.
Shroud time beyond the Flame
The Flame sets your base timer. Other effects stack on top of it, but stacking was nerfed in 1.0:
- Inner Fires skill: +60 seconds per rank, 3 ranks (PinDrop). Keen moved and adjusted this skill in 1.0.
- Shroud Survival Flask: +2:00. Greater Shroud Survival Flask: +4:00.
- Hourglass Capsules: much more common in 1.0, and they also drop from large Fell enemies.
- World setting: Shroud time from 50% to 200% (default 100%, Relaxed preset 150%).
Deadly Shroud doesn’t use this timer. It stays lethal until your Shroud Passage level (your Flame level) is high enough for that area.
