Historical no-boom option
This reproduces the archived no-boom function, not a PC-room price discount. The captured page has no active PC-room option.
Rules match the captured regional tables (2026-10-14 snapshot), not a live patch feed. Replacement equipment purchase prices are excluded. MVP discounts apply through the 15 → 16 attempt. Sources and formulas.

Monte Carlo estimates vary with seed and trial count. Min/max are observed samples, not theoretical limits. Boom percentiles use linear interpolation and may be fractional.

Plan your next upgrade
Replacement planning
Read destroyed equipment separately from mesos. Add spare-item costs before choosing an upgrade budget.
Risk reserve
Run percentiles with the same seed and enough trials to see how much a conservative budget exceeds the mean.
Star Force 21 to 22 Cost — Level 200 Arcane FAQ
What does 200 equipment, 21 → 22 stars include?
The saved plan starts at 21 stars and stops at 22, on level-200 equipment. It uses GMS 30 Stars, Safeguard on and no event initially. Change any control to compare another plan.
Are replacement items included in mesos?
No. The mesos result covers enhancement attempts. Expected destroyed items are reported separately; multiply by your replacement price if you want an additional equipment budget.
Why do the average and sampled mean differ?
The displayed expected value is solved from the upgrade states. Percentiles come from finite seeded simulations, whose mean can differ from the exact expectation.
What is Shining Star Force in this calculator?
It combines 30% off meso costs with 5/10/15 guaranteed successes where the selected rules support them. It is not a forecast of the next event date.
When should I calculate percentiles again?
After changing an input. Exact averages update immediately, but the old sample table is hidden until a new simulation finishes.
Does a 95th-percentile cost guarantee success?
No. About 5% of modeled sessions can cost more. Observed sample minimum and maximum are not theoretical limits.
How do I compare this with MathBro?
Match server rules, equipment level, start and target stars, Star Catch, Safeguard, MVP, event and trial count. Seeded samples are not expected to equal another random run; compare rules and sufficient samples, not one maximum.
Can I reuse this preset for another equipment level?
Change the level first: enhancement costs depend on equipment level. Keep the same regional rule set and event flags for a meaningful comparison.
Compare the right numbers
Exact expectation
A state-based average that updates with inputs; not a percentile.
Seeded simulation
A sample distribution for cost and booms; trial count and seed affect percentiles.
MathBro comparison
Match the selected rules and flags first. Different random sessions need not share a sample maximum.
