Crystal Laboratory
More actions
The Crystal Laboratory is a building in Whiteout Survival where you exchange basic Resources for Fire Crystals on a daily basis.
Exchanges
Each exchange trades a fixed amount of Meat, Wood, Coal and Iron for Fire Crystals. The cost rises with the refinement tier, from 5,000 of each resource at the 1st refinement up to 50,000 of each at the 8th. The number of exchanges available per day depends on your Fire Crystal level: 5 exchanges at FC5, 6 once the War Academy is built, 7 at FC8 and 8 at FC10. From FC6 onward, higher-value super refinements also become available.
Yield
Each exchange yields 1 to 5 Fire Crystals on a weighted table:
| Fire Crystals | Chance |
|---|---|
| 1 | 40% |
| 2 | 30% |
| 3 | 15% |
| 4 | 10% |
| 5 | 5% |
Super refinements
From FC6 onward, super refinements convert Fire Crystals into Refined Fire Crystals — up to 100 per week, across 5 tiers of 20 refinements each, with the Fire Crystal cost rising tier by tier (starting at 20 Fire Crystals per refinement). Refined Fire Crystals are required for the highest Fire Crystal Age upgrades and War Academy (T12) research.
