'''Fire Crystals''' are a rare and powerful currency in [[Whiteout Survival]], described in lore as "a mysterious crystal that is alive and contains unimaginably strong power." They are the primary resource for late-game progression beyond Furnace level 30.

== Overview ==

Fire Crystals serve as the foundation of the late-game Fire Crystal (FC) progression system, which includes:
* Upgrading the [[Furnace]] beyond level 30
* Constructing and upgrading Fire Crystal variants of core [[Buildings]]
* Researching advanced technologies in the [[War Academy]]
* Obtaining Fire Crystal Shards for [[War Academy]] research costs
