Pick the buildings you want to raise and a weekly Super Refinement pace. You get the number of weeks to bank the RFC you need, and the Fire Crystal it costs.
Free RFC covers weekly shop exchanges that cost no Fire Crystal.
| Building | Current | FC6 | FC7 | FC8 | Fire Crystal | RFC | Build days |
|---|
The Furnace caps every other building. Raise it first when you actually build.
Tap a row to recalculate at that pace. The faster you go, the more Fire Crystal each RFC costs.
| Week | Refines | Split by day | FC spent | RFC gained | RFC banked | FC left over |
|---|
The Fire Crystal needed for the upgrades themselves is set aside every week, and only the surplus goes into refining.
Super Refinement resets at the weekly reset, capped at 100 per week. The first refinement of each day costs half.
| Tier | FC per refine | RFC expected | Outcome |
|---|---|---|---|
| 1–20 | 20 | 1.45 | 1 at 65% / 2 at 25% / 3 at 10% |
| 21–40 | 50 | 2.15 | 2 at 85% / 3 at 15% |
| 41–60 | 100 | 3.175 | 3 at 85% / 4 at 12.5% / 5 at 2.5% |
| 61–80 | 130 | 3.435 | 3 at 75% / 4 at 15% / 5 at 5%, etc. |
| 81–100 | 160 | 3.71 | 3 at 70% / 4 at 12% / 5 at 9%, etc. |
