Mastery Calculator
Simple remaining mastery and percent bar — does not simulate per-move XP gains or bonus weekends.
Mastery progress
Linear remaining mastery only — does not model per-move XP rates or bonuses.
Progress0.0%
600 mastery remaining.
Formula assumptions
Estimates only — verify in-game before committing beli, fruits, or stat resets.
- Progress is linear: remaining = target − current.
- Does not apply game-specific mastery gain rates per ability.
How it works
Enter optional subject label, current mastery, and target mastery. The bar shows current ÷ target when target > 0. Target cannot fall below current.
Example
Current 350 toward 600 means 250 remaining (~58.3% on the bar). Use this to track grind checkpoints, not time-to-complete.
