Comprehensive Guide: How to Calculate Critical Value in Genshin Impact
Understanding and optimizing your critical values in Genshin Impact is essential for maximizing your character’s damage output. This comprehensive guide will walk you through the mathematics behind critical hits, how to calculate your optimal critical ratio, and practical strategies to improve your DPS.
1. Understanding Critical Mechanics in Genshin Impact
Genshin Impact’s damage calculation system involves several key components that interact to determine your final damage output. The critical system consists of two primary statistics:
- CRIT Rate: The probability (expressed as a percentage) that your attack will land as a critical hit
- CRIT DMG: The additional damage multiplier applied when a critical hit occurs
The relationship between these statistics follows a diminishing returns curve, which means that simply maximizing one at the expense of the other isn’t always optimal.
2. The Critical Value Formula
The expected damage from your attacks can be calculated using this formula:
Expected Damage = Base Damage × (1 + (CRIT Rate × CRIT DMG))
Where:
- Base Damage is your attack value after all other multipliers
- CRIT Rate is expressed as a decimal (50% = 0.5)
- CRIT DMG is expressed as a multiplier (150% = 1.5)
3. Calculating Optimal CRIT Ratio
The optimal balance between CRIT Rate and CRIT DMG is generally considered to be when:
CRIT Rate × 2 ≈ CRIT DMG
For example:
- If your CRIT Rate is 50% (0.5), your CRIT DMG should be about 100% (1.0)
- If your CRIT Rate is 70% (0.7), your CRIT DMG should be about 140% (1.4)
However, this is a simplification. The actual optimal ratio depends on your specific character, weapons, and artifacts.
4. Character-Specific Considerations
Different characters have different base stats and scaling factors that affect their optimal critical ratios:
| Character Type | Base CRIT Rate | Recommended CRIT Ratio | Example Characters |
|---|---|---|---|
| High Base CRIT | 15-25% | 1:1.5 | Keqing, Mona, Rosaria |
| Low Base CRIT | 5-10% | 1:2 | Xiao, Hu Tao, Eula |
| Balanced | 10-15% | 1:1.8 | Diluc, Ganyu, Ayaka |
| Support/DPS Hybrid | 5-10% | 1:1.5 | Xiangling, Xingqiu, Fischl |
5. Weapon and Artifact Impact
Your equipment significantly affects your critical stats:
- Weapons: Many 5-star weapons provide substantial CRIT Rate or CRIT DMG bonuses. For example:
- Skyward Blade: 4% CRIT Rate base stat
- Amos’ Bow: 49.6% CRIT DMG at R1
- Jade Cutter: 44.1% CRIT Rate at R1
- Artifacts: The Gladiator’s Finale and Shimenawa’s Reminiscence sets provide CRIT DMG bonuses, while Pale Flame offers both CRIT Rate and CRIT DMG.
6. Advanced Calculations: Damage Multipliers
To accurately calculate your critical value, you need to account for all damage multipliers:
- Base ATK: Character ATK + Weapon ATK
- Skill Multiplier: Different abilities have different base multipliers
- Elemental Mastery: Affects reaction damage
- Enemy RES: Reduces damage based on enemy resistance
- Defense Reduction: Ignores a percentage of enemy defense
- Damage Bonuses: Elemental damage bonus, physical damage bonus, etc.
The complete damage formula is:
Final Damage = Base ATK × Skill Multiplier × (1 + CRIT Rate × CRIT DMG) × (1 + Elemental Bonus) × (1 – Enemy RES) × Reaction Multiplier × Defense Multiplier
7. Practical Optimization Strategies
To maximize your critical value:
- Identify Your Current Ratio: Use the calculator above to determine your current CRIT Rate to CRIT DMG ratio
- Adjust Artifact Substats: Farm artifacts that balance your ratio toward the optimal 1:2 range
- Consider Weapon Choice: Some weapons provide better critical stats for your specific character
- Use Team Synergies: Certain team compositions can provide CRIT Rate or CRIT DMG buffs (e.g., Rosaria’s C6, Mona’s Omen)
- Monitor Enemy RES: Use RES-shredding abilities (like Viridescent Venerer) to improve damage consistency
8. Common Mistakes to Avoid
Many players make these critical calculation errors:
- Overvaluing CRIT DMG: Having 200% CRIT DMG with 30% CRIT Rate is often worse than balanced stats
- Ignoring Base ATK: CRIT stats multiply your base damage – don’t neglect ATK% and flat ATK
- Forgetting Reaction Multipliers: Vaporize/Melt can double your damage, changing optimal ratios
- Not Accounting for Buffs: External CRIT buffs (like Bennett’s C6) affect your optimal ratio
- Static Builds: Different enemies and scenarios may require adjusted critical ratios
9. Data-Driven Optimization
Research from gaming theory suggests these general guidelines for critical optimization:
| Scenario | Optimal CRIT Rate | Optimal CRIT DMG | Expected DPS Gain |
|---|---|---|---|
| General DPS | 65-75% | 130-160% | 15-20% |
| Reaction-Based | 55-65% | 120-150% | 25-35% |
| High Multiplier | 70-80% | 150-180% | 20-25% |
| Consistent Damage | 80-90% | 100-120% | 10-15% |
These values assume you’re using appropriate damage bonuses and reaction multipliers for your character.

- Artifacts: Pale Flame (CRIT Rate/DMG)
- Target Ratio: 80%+ CRIT Rate / 180%+ CRIT DMG
- Result: ~35% DPS increase with superconduct reactions
13. Mathematical Deep Dive: Expected Value Calculation
For those interested in the underlying mathematics, let’s examine the expected value calculation in detail:
The expected damage (E) from an attack can be expressed as:
E = D × [P × (1 + C) + (1 – P)]
Where:
- D = Base damage (ATK × Skill Multiplier × Other Multipliers)
- P = CRIT Rate (as decimal)
- C = CRIT DMG (as decimal, so 150% = 1.5)
Simplifying:
E = D × [1 + (P × C)]
To find the optimal ratio between P and C, we can take the derivative with respect to P and C and set them equal, assuming we can trade between them at a fixed rate (typically 1% CRIT Rate ≈ 2% CRIT DMG from artifact substats).
The optimal condition occurs when:
∂E/∂P = 2 × ∂E/∂C
Solving this gives us the approximate 1:2 ratio mentioned earlier, though the exact ratio depends on your specific damage multipliers and external buffs.
14. Practical Application: Artifact Farming Guide
When farming artifacts to optimize your critical values:
- Prioritize Main Stats:
- Sands: ATK% (usually best for DPS)
- Goblet: Elemental/Physical DMG Bonus
- Circlet: CRIT Rate or CRIT DMG (whichever you need more)
- Substat Priority:
- CRIT Rate/DMG (balance toward your target ratio)
- ATK%
- Elemental Mastery (for reaction-based characters)
- Flat ATK
- Farming Strategy:
- Use the artifact strongbox to target specific slots
- Focus on one domain at a time to conserve resin
- Upgrade 4-star artifacts to +16 before deciding to keep them
- Use the “lock” feature for good artifacts to prevent accidental feeding
- Evaluation Method:
- Use the calculator above to test potential artifact combinations
- Compare the expected DPS values rather than individual stats
- Consider the opportunity cost of resin spent on marginal upgrades
15. Team Composition Considerations
Your team composition can significantly affect your optimal critical ratio:
- CRIT Buffs:
- Rosaria C6: +15% CRIT Rate for party
- Mona Omen: +60% CRIT DMG for one hit
- Kazuha C2: +200 EM, indirectly boosting reaction damage
- Reaction Enablers:
- Xingqiu: Enables consistent vaporize reactions
- Fischl: Provides electro for overload/superconduct
- Bennett: ATK buff that scales with your CRIT stats
- RES Shred:
- Viridescent Venerer: -40% RES for affected element
- Zhongli: -20% RES for all elements
- Alhaitham EM sharing: Indirect RES reduction via reaction damage
When these buffs are present, you may want to adjust your artifact substats to take advantage of the external CRIT buffs, potentially shifting more toward CRIT DMG if you’re receiving significant CRIT Rate buffs from teammates.
16. Advanced Topics: Simulation and Probability
For truly optimized builds, some players use simulation techniques:
- Monte Carlo Simulation: Running thousands of simulated attacks to determine average DPS
- Damage Distribution Analysis: Examining the probability distribution of damage values
- Resin Efficiency Modeling: Determining whether farming for a specific substat is worth the resin cost
- Opportunity Cost Analysis: Comparing the value of improving CRIT stats vs. other stats like ATK% or EM
While these methods are more complex, they can provide additional insights for min-maxing your characters.
17. Common Myths Debunked
Let’s address some persistent misconceptions about critical values:
- “More CRIT DMG is always better”: False – without sufficient CRIT Rate, high CRIT DMG is wasted
- “You should always aim for 100% CRIT Rate”: False – the DPS gain diminishes as you approach 100%
- “CRIT stats don’t matter for support characters”: False – many supports benefit from CRIT stats (e.g., Fischl, Xiangling)
- “The 1:2 ratio is universal”: False – it varies based on your specific multipliers and external buffs
- “Substats don’t matter if main stats are good”: False – substats often contribute 30-40% of your total CRIT value
18. Tracking Your Progress
To effectively optimize your critical values over time:
- Document Your Builds: Keep records of your artifact stats before and after upgrades
- Use Spreadsheets: Track your CRIT ratios and DPS improvements over time
- Set Milestones: Establish clear goals for each character (e.g., “Reach 70/150 CRIT ratio”)
- Compare Before/After: Use the calculator to see the impact of each artifact upgrade
- Share with Community: Participate in theorycrafting discussions to get feedback on your builds
19. Future Updates and Meta Shifts
