We do not ship datamined combat formulas. You supply base damage and modifiers; the service only applies the documented stack rule.

Can multipliers be below 1?

Values ≤ 0 are ignored for multiplier rows. Use flats for reductions if you model them manually.

Enter a base hit from your testing, then add labeled modifiers. Output is a planning estimate only.

Damage estimate

Planning model: (base + flat bonuses) × product(multipliers). Does not simulate enemy defense, level scaling, or move-specific procs.

Formula assumptions

Estimates only — verify in-game before committing beli, fruits, or stat resets.

Formula: (base + sum(flat modifiers)) × product(multipliers).
Enemy defense, level difference, and internal move scaling are excluded.
Modifier values are user-supplied estimates unless you cite a source in the label.

How it works

Base damage should come from your own observation (training dummy, boss hit, etc.). Add multipliers for buffs that scale damage proportionally and flat entries for additive bonuses.

Invalid or non-finite modifier values are skipped silently to keep the stack stable.

Example

Base 500 with a ×1.15 fruit buff and +50 flat yields (500 + 50) × 1.15 = 632.5 before rounding display — still not a promise of in-game numbers on players.
