Dokkan Battle Damage Estimator
Use this calculator to estimate normal hit damage, critical hit damage, and expected average damage for a super attack.
What this Dokkan damage calculator is for
This page gives you a practical way to estimate offensive output in Dokkan Battle. It is designed for quick team-building checks: how hard a unit should hit, how much value support gives, and how critical chance changes your average turn damage.
Because Dokkan has many hidden or edge-case mechanics, this is an estimate tool, not a frame-perfect simulator. Still, it is very useful for comparing units, rotations, and build choices.
Damage model used in this calculator
The calculator follows a simplified multi-step model:
- Base Attack: your character's ATK stat.
- Leader + Passive + Turn Buffs: applied as multipliers to build pre-super ATK.
- Super Attack Multiplier: converts attack into super attack power.
- Type Modifier: used for non-critical hits only.
- Enemy DEF: subtracted from non-critical damage.
- Enemy Damage Reduction: final mitigation layer on both normal and crit results.
- Crit Model: 1.9x multiplier, neutral typing behavior, and DEF ignored in this simplified approach.
Core formula
Pre-Super ATK = Base ATK × (1 + Leader%) × (1 + Passive%) × (1 + Link% + Support% + Active%)
Super Power = Pre-Super ATK × SA Multiplier
Normal Final = max((Super Power × Type) - Enemy DEF, 0) × (1 - Damage Reduction)
Crit Final = (Super Power × 1.9) × (1 - Damage Reduction)
How to use this tool effectively
1) Start from realistic combat values
Use the ATK and buffs your unit actually gets on that turn. If your passive ramps or stacks, enter the value at the specific moment you care about.
2) Match the enemy profile
Red Zone bosses and newer difficult content often have heavy DEF or damage reduction. Adjust both fields. If you only change one, your estimate can be misleading.
3) Evaluate expected value, not only peak screenshots
Peak crit numbers are exciting, but the expected average damage is better for consistent performance comparisons, especially between builds with different critical rates.
Example scenario
Suppose your unit has 20,000 base ATK, double 170% leaders, 250% passive, 40% link buff, 30% support, 5.05 SA multiplier, and faces a boss with 300,000 DEF + 20% damage reduction at neutral typing.
With a 30% crit chance, you can quickly see three important values:
- Normal hit output in your current turn setup
- Critical hit output if the crit procs
- Expected average damage across many attacks
This helps decide if you need more support, a different linking partner, or a crit-focused hidden potential route.
Important limitations and notes
- This is a simplified calculator and does not model every hidden modifier in the game engine.
- Some unit passives apply conditionally (HP thresholds, enemy count, slot position, intro buffs).
- Additional supers, counters, nullification-triggered effects, and true turn-by-turn stacking are not simulated automatically.
- If a unit has unique wording (for example, "ATK +X% when performing Super Attack"), you may need to manually adapt percentages.
FAQ
Does this calculator work for all units?
It works as a universal estimate for most units, but very unique kits may need manual interpretation.
Why does critical damage look much higher?
In this model, crit uses a 1.9x multiplier and bypasses the non-crit type disadvantage/DEF step, which can massively increase output versus high-DEF enemies.
Can I use this for build decisions?
Yes. Compare expected damage between crit chance levels, support levels, or different rotations to make smarter build choices.
