Option Calculator

Introduction

The Option Calculator helps determine which outfit should be bound and the optimal substat distribution to achieve maximum damage output.
Only offensive stats are considered in the formula—crit rate, enemy defense, and other factors are not included.

This calculator is the web version of BD2 Max Damage SubStat Ratio (Original creator: キリユ)

Quick Start

1. Select a character.
2. Adjust Collection Bonus / External Buffs based on your situation, and set the correct damage type for the character.
3. Modify the enhancement score for each gear part.
4. Click the Auto Calculate button.

Once the auto calculation is complete, a result window will appear. The substat combination with a highlighted background indicates the optimal result.
Based on the above example, we can conclude:

Neutral:

1. Bind the outfit Rodev's Star.
2. Use Crit DMG as the main stat of the exclusive weapon.
3. SubStat Ratio: ATK * 0 / ATK(%) * 4 / Crit DMG * 11

Advantage:

1. Bind the outfit Neon Stalker.
2. Use Crit DMG as the main stat of the exclusive weapon.
3. SubStat Ratio: ATK * 0 / ATK(%) * 5 / Crit DMG * 10

Based on this result, distribute the 15 substats accordingly.

Custom Settings

1. Character Settings

1. Character Stats: After selecting a character, their base max-level stats will autofill. If the character is not max level, adjust the stats manually.
2. Engraving / Awakening: Defaults to max. Adjust according to your character’s actual state.
3. Outfit Stats: Defaults to max. Adjust based on your outfit enhancement level.
4. Bound Outfit: If checked, the calculator will force use of the selected outfit during calculations.

Each field has quick buttons to reset or maximize values.

2. Collection Bonus / External Buffs / Other Settings

1. Collection Bonus: Defaults to max. Adjust as needed.
2. External Buffs: If you use Refithea or Diane as support, or the skill provides buffs, input the values here.
   (See the FAQ for why ATK/Magic ATK is not included here)
3. Damage Type: Adjust according to the character's actual damage type.
4. Number of SubStats: Since some substats might be allocated to defense or other needs, you can customize the number (0 to 15).

Quick support buff buttons are provided and values are auto-summed.

3. Gear Settings

Click on the score to quickly set the enhancement level.

If gear is specified, it will be used in the auto calculation (exclusive weapon's main stat can also be set).

4. Current Character Stats

The Option Calculator also compares your current character stats with the optimal distribution.
This shows how much potential damage increase you can get by changing gear.

After inputting your character’s current stats and calculating, the result will show the potential damage growth rate.

FAQ

Q. Why is there no ATK / Magic ATK field in External Buffs?

A. According to the damage formula, ATK and Magic ATK are separate multipliers. They don't mix with base stats, so including or excluding them from buffs won’t affect substat ratio results.
