Whiteout Survival Research & War Academy Guide
Once your Furnace reaches Level 30, buildings upgrade through Fire Crystal stages FC1 to FC10 (5 sub-stages per level). At FC5 you unlock War Academy T11 Helios troop research, and starting at FC6 upgrades require Refined Fire Crystals.
⚡ Key Takeaways:
- Each FC level (FC1–FC10) has 5 sub-upgrades across the Furnace, Embassy, and Troop Camps.
- Perform only 1–2 Super Refinements per day in the Crystal Laboratory to avoid escalating costs.

⚡ Quick Tactical Cheat Sheet
Whiteout Survival: Optimal Meta Play vs. Common Resource Traps
✓ Do This (Optimal Meta)
- ●Join Bear Trap rallies with Jessie, Jasser, or Seo-yoon in the far-left slot (+25% damage/attack from their 1st Expedition skill).
- ●Activate Chief Order Double Time (-20% construction time) + Cave Hyena pet skill + VP buff BEFORE clicking any FC1–FC10 Furnace upgrade.
- ●Use a 10% Infantry / 10% Lancer / 80% Marksman troop formation for Bear Trap, and 50% / 20% / 30% for Sunfire Castle PvP.
✕ Avoid This (Resource Trap)
- ●Never join a Bear Trap rally with Molly, Gina, or Cloris in the far-left slot—they overwrite your alliance's 4-skill damage cap.
- ●Avoid doing more than 1–2 Super Refinements per day in the Crystal Laboratory (cost spikes sharply after the first two).
- ●Do not leave troops idle in your city during the SvS Battle Phase if you are not actively shielding or reinforcing Sunfire Castle.
