Genshin Impact Artifact Stat Calculator: Mastering the RNG
In Genshin Impact, your artifacts are the single most important factor in determining your team's power level. While character levels and talent upgrades have a clear progression, artifacts are governed by intense RNG. To make sense of this chaos, veteran players use specific metrics: Crit Value (CV) and Roll Value (RV). This guide and Genshin Impact Artifact Stat Calculator will help you determine which artifacts are legends and which belong in the trash.
The Core Metric: What is Crit Value (CV)?
Crit Value is a simplified way to measure how much "weight" an artifact adds to your critical hit potential. Since the game weights Crit Rate twice as heavily as Crit Damage (look at your circlet main stats for proof), the formula is designed to respect that balance.
CV = (Crit Rate × 2) + Crit Damage
For example, if an artifact has 10% Crit Rate and 20% Crit Damage, its CV is: (10 * 2) + 20 = 40 CV. This is the community standard for a "perfect" or "godly" artifact.
Roll Value (RV): Measuring Efficiency
Roll Value is a more advanced metric. Every substat roll has a range. For example, Crit DMG can roll as 5.4%, 6.2%, 7.0%, or 7.8%. A roll of 7.8% is a "Max Roll" (100% RV), while 5.4% is a "Low Roll" (70% RV). - High RV: Your artifact got the maximum possible boost from each upgrade. - Low RV: Even if you hit the right stats, the numbers themselves are lower than they could be.
Artifact Grading Scale
| Crit Value (CV) | Grade | Recommendation |
|---|---|---|
| 10 - 20 | D | Placeholder for early game. |
| 20 - 30 | C | Basic endgame functional build. |
| 30 - 40 | B / A | Strong pieces. Keep these! |
| 40 - 50 | S | Godly tier. Rare and powerful. |
| 50+ | SSS | The "Unicorn." Top 0.01% of players. |
Most Searched: Substat Roll Ranges (5-Star Artifacts)
Understanding the minimum and maximum rolls helps you use the Artifact Stat Calculator more effectively. Here are the 5-star values:
- Crit Rate: 2.7% / 3.1% / 3.5% / 3.9%
- Crit Damage: 5.4% / 6.2% / 7.0% / 7.8%
- ATK / HP / DEF %: 4.1% / 4.7% / 5.3% / 5.8%
- Elemental Mastery: 16 / 19 / 21 / 23
- Energy Recharge: 4.5% / 5.2% / 5.8% / 6.5%
3-Stat vs 4-Stat Starters: The Math of Potential
When an artifact drops, it can have either 3 or 4 substats. - 3-Stat Starter: Gains its 4th stat at Level 4, then upgraded at 8, 12, 16, 20 (4 upgrades total). - 4-Stat Starter: Upgraded at levels 4, 8, 12, 16, 20 (5 upgrades total).
A 4-stat starter artifact is mathematically superior because it effectively gives you one "free" roll. If you are chasing a 50 CV artifact, it must be a 4-stat starter.
The Main Stat Trap: Why Artifact Type Matters
Substats are useless if the Main Stat is wrong. For example: - Elemental Mastery: Crucial for Kazuha, Nahida, and Bloom triggers. - Energy Recharge: Crucial for Raiden, Xingqiu, and Xiangling. - Elemental DMG Bonus: Mandatory for almost all Main DPS units on the Goblet slot.
Before using the calculator to check your CV, ensure the artifact's main purpose matches your character's scaling. A 40 CV ATK% Goblet is often worse than a 20 CV Electro DMG Goblet for an Electro DPS.
Artifact Strongbox: The Secret to Efficiency
Once you reach Adventure Rank 45, you can use the Artifact Strongbox at any crafting bench. You trade 3 useless 5-star artifacts for 1 new piece of a specific set. - Statistics: Strongbox artifacts have a higher chance of being "4-stat starters" compared to domain drops. - Efficiency: This is the best way to farm tough sets like Gladiator's Finale or Crimson Witch of Flames while spending your resin elsewhere.
Advanced Technique: Roll Value (RV) for Supports
CV is great for DPS, but what about supports like Bennett or Yun Jin? - **Bennett** needs Energy Recharge and Max HP for his heals. - **Yun Jin** needs Defense and Energy Recharge.
In these cases, you should use RV (Roll Value) instead of CV. Calculate the RV of the stats you need. An artifact with 100% RV in Defense and ER is "Godly" for Yun Jin, even if its CV is zero.
The "Golden Ratio" of Crit
Our calculator helps you find your individual artifact stats, but how do they fit together? The goal for 90% of characters is a 1:2 ratio. - 70% Crit Rate / 140% Crit Damage. - 80% Crit Rate / 160% Crit Damage.
If your Crit Rate is too low (e.g., 20/200), your average damage will be inconsistent and lower than a balanced build. Always aim for at least 60% Crit Rate before stacking more Crit Damage.
Conclusion: Knowledge is Power
Stop guessing which artifact to upgrade. By using the Genshin Impact Artifact Stat Calculator and understanding metrics like CV and RV, you can manage your resources more effectively. Build your characters with the confidence of a mathematician and the power of a whale. Teyvat awaits your perfect build!
Endgame Farm Checklist
- Target 30+ CV for Main DPS artifacts.
- Target 200%+ ER for Burst-reliant supports.
- Always use an Elemental DMG Goblet for DPS.
- Level up to +20 only if the rolls are good at +12.
