Super Refinement Efficiency
More Super Refinements always produce more refined Fire Crystals in total, but every later refinement band returns less rFC for each Fire Crystal spent.
Plan your rFC goal
Enter your goal and deadline. The planner chooses the fewest Super Refinements per week that can reach it, keeping your FC to rFC return as efficient as possible.
Do 18 for 1 week, then 17 for 3 weeks

Weekly pace plan
Suggested order: 18 for the first 1 week, then 17 for the remaining 3 weeks. Doing the higher weeks first builds the most useful buffer for later results.
Your pace target is 25 rFC per elapsed week. The cumulative checkpoints below show how much rFC to have by the end of each week.

| Week | Refinements | Expected total | Pace target |
|---|---|---|---|
| 1 | 18 | 26.1 rFC | 25 rFC |
| 2 | 17 | 50.75 rFC | 50 rFC |
| 3 | 17 | 75.4 rFC | 75 rFC |
| 4 | 17 | 100.05 rFC | 100 rFC |
Results use expected rFC returns and the lowest weekly FC cost from the daily half-price refinements.
There is no efficiency tier to aim for
The daily half-price refinements lower the weekly FC cost, but they never create a point where the overall rFC return per FC improves. Choose a weekly count based on the rFC you need and the FC you are willing to spend, not to reach a more efficient tier.
Weekly comparison
This comparison uses one half-price refinement on the first day, then places the final six refinements on the remaining six days to get the lowest possible weekly FC cost.

Return by refinement band
Later bands award more rFC per refinement, but the FC cost rises faster than the expected output.
