How to Optimize Crit Rate and Crit Damage
In almost every RPG, MMO, or Gacha game (like Genshin Impact, Honkai: Star Rail, or World of Warcraft), maximizing your Damage Per Second (DPS) often comes down to balancing three main stats: Total Attack, Critical Rate, and Critical Damage.
A common mistake players make is stacking too much Crit Damage while ignoring Crit Rate, resulting in "big numbers" that rarely appear. Conversely, having 100% Crit Rate with very low Crit Damage results in consistent but weak hits.
The Average Damage Formula
This calculator determines the "Average Damage" (often called Effective Attack or Critical Value) using the following mathematical formula:
Average Damage = Attack × (1 + (Crit Rate% × Crit Damage%))
Note: In the calculation, percentages are converted to decimals (e.g., 50% = 0.50). Also, Crit Rate is usually capped at 100% (1.0) because you cannot crit more often than every hit.
The Golden Ratio (1:2 Rule)
For most games, stats are allocated in a way where obtaining 1% Crit Rate "costs" the same amount of item budget as 2% Crit Damage. Mathematically, to maximize the area of the rectangle defined by these stats, you should aim for a 1:2 ratio.
- If your Crit Rate is 50%, your ideal Crit Damage is 100%.
- If your Crit Rate is 70%, your ideal Crit Damage is 140%.
Pro Tip: Once your Crit Rate reaches 100%, any further increase in Crit Rate is wasted stats. At that point, you should dump all remaining stats into Attack or Crit Damage.
When to Use This Calculator
Use this tool when you have two different artifacts, relics, or gear pieces and you aren't sure which one provides more damage. Sometimes, a piece with lower Crit Damage but higher Attack or Crit Rate will actually yield a higher average damage output.
