Enshrouded Flame Upgrades
Strengthening the Flame raises your world's progression, not the size of one base. Check the offerings and happy survivors needed for each upgrade, plus the default Shroud time, altar limit and water-source limit you gain, from your first upgrade through Flame level 11.

Flame strength or building area?
Strengthen the Flame changes world progression. Upgrading a specific altar expands that base instead; it does not increase Flame strength.
Why is my Flame upgrade blocked?
The survivor count is too low
Rescuing someone is not the whole requirement. Summon them at a base, give them an assigned sheltered bed and food, then check the altar's count again. Later upgrades need more people than the five early craftspeople. Pets do not count as survivors.
You have the materials but the upgrade is unavailable
Choose Strengthen the Flame and check the next level's exact offering and happy-survivor requirement. A material with a similar name or a processed version may not count. Meet the previous Flame level first.
Your building area didn't grow
Strengthening the Flame and expanding one altar are separate actions. Use that altar's building-area upgrade when you need more protected space; increasing its area does not raise your Flame strength.
Your Shroud timer doesn't match the listed time
The times here are the base values for default world settings. Food, skills and world settings can change your timer. More time is not permission to ignore a Deadly Shroud warning or other hazards.
Sources and version notes
Offerings and survivor requirements were checked against readable game-file references for the 1.0 release series. The ten attainable upgrades end at Flame level 11. Shroud times, altar limits and water-source limits are default values, not a prediction of every customized world or character's effective stats. Additional crafting requirements still apply to unlocked recipes.
