Star Force Cost & Boom Estimator
Configure your item level, current stars, target stars, and Safeguard toggle (available from 12+ stars). Calculations follow official KMS star force rates (success%, destruction%, cost scaling). Results are expected averages based on thousands of simulated enhancements.
Estimates based on MapleStory 2026 rates. Actual RNG may vary. Safeguard doubles cost but prevents destruction.
Star Force Stat Boost Calculator
Each star adds Attack/Magic Attack and primary stats (STR/DEX/INT/LUK). Use this table to gauge power gains per star for a typical weapon/armor (Level 160).
| Stars | Weapon ATT (2H) | Armor Main Stat | Cumulative ATT (Weapon) |
|---|---|---|---|
| 0→5 | +9 ATT | +15 main stat | 9 |
| 6→10 | +11 ATT | +20 main stat | 20 |
| 11→15 | +18 ATT | +30 main stat | 38 |
| 16→17 | +12 ATT | +24 main stat | 50 |
| 18→20 | +21 ATT | +36 main stat | 71 |
| 21→22 | +14 ATT | +30 main stat | 85 |
2026 Insight: 22-star weapons get ~85 ATT bonus (~13% final damage for most classes). Always prioritize weapon star force before armors.

Cost Saving Strategies & 2026 Meta
- Use Star Catch / Spell Trace Fever: reduces cost by up to 5% per attempt.
- 30% Off Star Force events: best time for 17+ star pushes, cuts total cost by ~30%.
- Safeguard 20→22: extremely expensive but prevents total loss of high-value items like Arcane/Grandis gear.
- Expected boom for 22-star without safeguard: ~35-40% chance to boom at least once. Plan replacement spares.
- 2026 inflation update: meso costs slightly increased for items above 200, but our calculator accounts for modern coefficients.
