Fire Crystals
Crystals needed for FC upgrades.
Dataset Computed from a cited, versioned public dataset. The game may change values.
How it is calculated
The Fire Crystal calculator shows exactly how many Fire Crystals and Refined Fire Crystals your FC upgrades need, across every building you plan to push.
It uses the same cumulative building data as the Buildings calculator, limited to buildings that have Fire Crystal levels, and lists the two crystal currencies first. Every FC stage and sub-level (FC 3-1 … FC 3-4) is a separate step with its own cost.
Missing = needed − in stock, never below zero.
Example
Furnace FC 1 → FC 3 and Command Center FC 1 → FC 2, 600 crystals in stock
Questions
- Does it include refining crystals?
- No. Refining has its own costs and limits; enter the refined crystals you already have and the tool shows what is missing.
