More actions
Refined Fire Crystal (RFC) is a high-tier progression resource in Whiteout Survival, derived from Fire Crystal. It is the primary currency for end-game War Academy (T12) research — the Exalted and Molten troop upgrades — used alongside Fire Crystal and Steel.
Acquisition
Refined Fire Crystal becomes available once the Crystal Laboratory is built, which requires reaching the first Fire Crystal Age and Furnace level 30.
- Crystal Laboratory — Super Refinements — the main source: Fire Crystals are converted into Refined Fire Crystals, up to 100 per week, across 5 tiers of 20 refinements each (the Fire Crystal cost rises tier by tier, starting at 20 Fire Crystals per refinement).
- Crystal Reactivation — event rewards during Fire Crystal reactivation periods.
- Other sources — the Fire Crystal Exchange, the Flame and Fangs event, and periodic packs and deals.
Uses
- War Academy (T12) — Exalted gear bonuses, Molten I/II/III upgrades and each branch's elite boss technology.
- High-level Fire Crystal Age progression — required from FC5 onward, alongside Fire Crystal, for the most advanced troop and building upgrades.
