📖 Overview
The Furnace is the most important building in Whiteout Survival. It determines your overall city level and unlocks the ability to upgrade other buildings. Every major milestone in the game requires upgrading your Furnace first. The Furnace can be upgraded from level 1 to 30, and then continues with Fire Crystal (FC) levels from FC 1 to FC 10, with sub-levels in between.
💡 Tips & Strategy
- Always prioritize Furnace upgrades to unlock new content and buildings.
- The Furnace determines the maximum level of all other buildings.
- FC levels (Fire Crystal) require Fire Crystals and Refined Fire Crystals.
- Use the Building Calculator to see upgrade times with your speed bonuses applied.
- Sub-levels (30-1, 30-2, etc.) must be completed before reaching the next full level.
