Genshin Artifact Calculator: Optimize Your Character Builds

Genshin Artifact Score Calculator

Input your artifact’s substat values and adjust weights to calculate its effective score for your character.

Substat Weights (Adjust for Character Priority)

These weights determine how important each substat is for your specific character build. Higher values mean more importance.

Typical 5-Star Artifact Substat Roll Ranges (Max Rolls at +20)

Substat	Min Roll (approx.)	Max Roll (approx.)	Max Rolls (+20)
Crit Rate (%)	2.7%	3.9%	23.4% (6 rolls)
Crit DMG (%)	5.4%	7.8%	46.8% (6 rolls)
ATK (%)	4.1%	5.8%	34.8% (6 rolls)
HP (%)	4.1%	5.8%	34.8% (6 rolls)
DEF (%)	5.1%	7.3%	43.8% (6 rolls)
Energy Recharge (%)	4.5%	6.5%	39.0% (6 rolls)
Elemental Mastery (flat)	16	23	138 (6 rolls)
Flat ATK	14	19	114 (6 rolls)
Flat HP	209	299	1794 (6 rolls)
Flat DEF	16	23	138 (6 rolls)

Note: These are approximate values for 5-star artifacts. Actual rolls can vary slightly. A +20 artifact typically has 5-6 substat rolls.

What is a Genshin Artifact Calculator?

A Genshin Artifact Calculator is an essential tool for players looking to optimize their character builds in Genshin Impact. It helps evaluate the quality and potential of an artifact by assigning a numerical score based on its substats and user-defined priorities. Instead of simply looking at raw numbers, a Genshin Artifact Calculator allows you to quantify how good an artifact is for a specific character or team composition.

This tool is particularly useful for discerning between seemingly similar artifacts, identifying “god rolls,” and making informed decisions about which artifacts to keep, upgrade, or discard. Given the immense RNG involved in artifact farming, a reliable Genshin Artifact Calculator streamlines the optimization process, saving players countless hours of trial and error.

Who Should Use a Genshin Artifact Calculator?

• Serious Players: Those aiming for optimal damage output, faster clear times in Spiral Abyss, or competitive showcases.
• New Players: To understand which stats are important and how to prioritize them early on.
• Theorycrafters: To test different stat weights and build hypotheses for new characters or meta shifts.
• Efficiency Seekers: Anyone who wants to minimize wasted resources (Mora, Artifact EXP) on suboptimal artifacts.

Common Misconceptions About Genshin Artifact Calculators

• “It tells me the absolute best artifact”: A Genshin Artifact Calculator provides a score based on *your* defined weights. The “best” artifact is subjective and depends on your character, team, and playstyle.
• “Higher score always means better”: While generally true, context matters. An artifact with a high score in Crit stats might be less valuable if your character needs significant Energy Recharge to function.
• “It replaces understanding game mechanics”: The calculator is a tool; it doesn’t replace the need to understand character scaling, elemental reactions, and team synergies. You still need to set appropriate weights.
• “Flat stats are always useless”: While generally less impactful than percentage stats, flat ATK/HP/DEF can still contribute, especially for characters with very low base stats or specific scaling. A Genshin Artifact Calculator can help quantify their minor contribution.

Genshin Artifact Scoring Formula and Mathematical Explanation

The core of any Genshin Artifact Calculator lies in its scoring formula, which translates various substat values into a single, comparable number. Our calculator uses a weighted sum approach, allowing you to customize the importance of each substat based on your character’s needs.

Step-by-Step Derivation

The formula calculates a “Total Artifact Score” by multiplying each substat’s value by its corresponding weight and summing these products. This allows for flexible prioritization.

1. Identify Substat Values: Extract the numerical value for each relevant substat (Crit Rate, Crit DMG, ATK%, HP%, DEF%, Energy Recharge, Elemental Mastery, Flat ATK, Flat HP, Flat DEF) from your artifact.
2. Assign Weights: Determine the importance of each substat for your specific character. For example, a DPS character might prioritize Crit Rate and Crit DMG heavily, while a support character might prioritize Energy Recharge or Elemental Mastery. These weights are multipliers.
3. Calculate Weighted Value for Each Substat: For each substat, multiply its numerical value by its assigned weight.
   • Weighted Crit Rate = Crit Rate (%) * Crit Rate Weight
   • Weighted Crit DMG = Crit DMG (%) * Crit DMG Weight
   • Weighted ATK% = ATK (%) * ATK% Weight
   • … and so on for all other substats.
4. Sum All Weighted Values: Add up all the individual weighted substat values to get the Total Artifact Score.
   
   Total Artifact Score = Weighted Crit Rate + Weighted Crit DMG + Weighted ATK% + ... + Weighted Flat DEF

Practical Examples (Real-World Use Cases)

Let’s illustrate how the Genshin Artifact Calculator can help you evaluate artifacts for different character archetypes.

Example 1: DPS Character (e.g., Hu Tao, Raiden Shogun)

For a main DPS character, Crit Rate, Crit DMG, and ATK% (or HP% for Hu Tao/Yelan, ER for Raiden) are paramount. Let’s use a common DPS weighting scheme:

• Crit Rate Weight: 2.0
• Crit DMG Weight: 1.0
• ATK% Weight: 1.0
• HP% Weight: 0.8 (if HP scaling)
• Energy Recharge Weight: 0.7 (if burst dependent)
• Other weights: 0.1 or 0.05

Artifact Substats:

• Crit Rate: 7.8%
• Crit DMG: 15.6%
• ATK%: 9.3%
• Energy Recharge: 5.8%
• Elemental Mastery: 39

Calculation using the Genshin Artifact Calculator:

• (7.8 * 2.0) + (15.6 * 1.0) + (9.3 * 1.0) + (5.8 * 0.7) + (39 * 0.5)
• 15.6 + 15.6 + 9.3 + 4.06 + 19.5 = 64.06

Output:

• Primary Result: Artifact Score: 64.06
• Crit Value (CV): (7.8 * 2) + 15.6 = 31.2
• Weighted ATK Score: 9.3
• Weighted ER Score: 4.06
• Weighted EM Score: 19.5

Interpretation: A score of 64.06 is excellent for a DPS artifact, indicating strong rolls into highly valued stats. The high Crit Value (31.2) confirms its DPS potential, and the decent EM contribution suggests it could work well in reaction teams.

Example 2: Support/Sub-DPS Character (e.g., Xingqiu, Nahida)

For a support like Xingqiu, Energy Recharge is crucial, followed by Crit stats and ATK%. For Nahida, Elemental Mastery is often prioritized above all else, then Crit stats.

Let’s consider an artifact for a Nahida build, prioritizing EM:

• Elemental Mastery Weight: 2.0
• Crit Rate Weight: 1.5
• Crit DMG Weight: 0.75
• Energy Recharge Weight: 0.5
• ATK% Weight: 0.3
• Other weights: 0.05

Artifact Substats:

• Elemental Mastery: 65
• Crit Rate: 3.5%
• Crit DMG: 7.0%
• Energy Recharge: 11.0%
• HP%: 5.8%

Calculation using the Genshin Artifact Calculator:

• (65 * 2.0) + (3.5 * 1.5) + (7.0 * 0.75) + (11.0 * 0.5) + (5.8 * 0.05)
• 130 + 5.25 + 5.25 + 5.5 + 0.29 = 146.29

Output:

• Primary Result: Artifact Score: 146.29
• Crit Value (CV): (3.5 * 2) + 7.0 = 14.0
• Weighted ATK Score: 0 (since ATK% was 0)
• Weighted ER Score: 5.5
• Weighted EM Score: 130.0

Interpretation: This artifact scores exceptionally high due to the massive Elemental Mastery roll, which is heavily weighted for Nahida. While the Crit Value is modest, the overall score reflects its strong utility for an EM-focused build. This demonstrates how a Genshin Artifact Calculator adapts to different character needs.

How to Use This Genshin Artifact Calculator

Our Genshin Artifact Calculator is designed for ease of use, helping you quickly assess your artifacts. Follow these steps to get the most accurate results:

Step-by-Step Instructions:

1. Locate Your Artifact: Open Genshin Impact and navigate to the character whose artifact you want to evaluate. Select the specific artifact.
2. Input Substat Values: Carefully enter the numerical values for each substat (Crit Rate, Crit DMG, ATK%, HP%, DEF%, Energy Recharge, Elemental Mastery, Flat ATK, Flat HP, Flat DEF) into the corresponding fields in the calculator. Ensure you enter percentages as whole numbers (e.g., 7.8 for 7.8%).
3. Adjust Substat Weights: This is the most crucial step. Modify the “Substat Weights” based on your character’s primary scaling and role.
   • For most DPS characters, Crit Rate (2.0) and Crit DMG (1.0) are high. ATK% (1.0) is also usually high.
   • For HP-scaling DPS (e.g., Hu Tao, Yelan), increase HP% Weight (e.g., 1.0-1.2) and potentially lower ATK% Weight.
   • For DEF-scaling DPS (e.g., Itto, Albedo), increase DEF% Weight (e.g., 1.0-1.2).
   • For Energy-hungry characters (e.g., Raiden Shogun, Xingqiu), increase Energy Recharge Weight (e.g., 1.0-1.5).
   • For reaction-focused characters (e.g., Nahida, Kazuha, Sucrose), significantly increase Elemental Mastery Weight (e.g., 1.5-2.0).
   • Flat stats (Flat ATK, HP, DEF) generally have very low weights (0.05-0.1) unless a character has extremely low base stats.
4. Calculate Score: The calculator updates in real-time as you change inputs. You can also click the “Calculate Score” button to refresh.
5. Reset (Optional): If you want to start over, click the “Reset” button to restore default values.
6. Copy Results (Optional): Use the “Copy Results” button to easily save the calculated score and intermediate values to your clipboard.

How to Read Results:

• Artifact Score: This is the primary highlighted number. A higher score indicates a better artifact based on your chosen weights. There’s no universal “good” score, as it’s relative to your weights and other artifacts. Aim for consistency across your character’s set.
• Crit Value (CV): A common metric for DPS artifacts, calculated as (Crit Rate * 2) + Crit DMG. A CV of 30+ is generally considered good for a 5-star artifact, 40+ is excellent, and 50+ is a “god roll.”
• Weighted ATK/ER/EM Scores: These intermediate values show the specific contribution of these stat categories to the total score, helping you understand where the artifact’s strength lies.

Decision-Making Guidance:

Use the Genshin Artifact Calculator to compare artifacts. If you have two artifacts for the same slot, input both into the calculator with the same weights. The one with the higher score is generally better for your specific build. Remember to consider your character’s overall stat distribution; sometimes a slightly lower score might be acceptable if it helps you reach crucial breakpoints (e.g., 180% ER for Raiden, 70% Crit Rate for consistent damage).

Key Factors That Affect Genshin Artifact Scores

The effectiveness of an artifact, and thus its score from a Genshin Artifact Calculator, is influenced by several interconnected factors. Understanding these helps you make better decisions during artifact farming and building.

1. Character Scaling: Different characters scale off different stats. A character like Hu Tao scales heavily with HP, while Itto scales with DEF. A Genshin Artifact Calculator’s weights must reflect this. Ignoring a character’s primary scaling will lead to misleading scores.
2. Team Composition & Synergies: Your team dictates stat priorities. A character in a Vaporize team will value Elemental Mastery highly, while a character in a Geo team might not. Energy Recharge needs are also heavily influenced by team energy generation.
3. Weapon Choice: Your weapon’s main stat and passive ability can significantly alter artifact priorities. A weapon providing high Crit Rate might allow you to prioritize Crit DMG more on artifacts, and vice-versa. Energy-generating weapons can reduce ER needs.
4. Artifact Set Bonuses: The 2-piece and 4-piece bonuses of artifact sets are crucial. Sometimes, a slightly lower-scoring artifact that completes a powerful 4-piece set bonus (e.g., Emblem of Severed Fate, Vermillion Hereafter) is better than a higher-scoring off-piece.
5. Substat Roll Quality & Quantity: Artifacts gain substat rolls at levels +4, +8, +12, +16, and +20. A “god roll” artifact has most or all of its rolls go into desirable substats with high values. The number of initial substats (3 or 4) also affects potential rolls.
6. Energy Requirements: Many characters rely on their Elemental Burst for significant damage or utility. Meeting their Energy Recharge requirements is often more important than maximizing raw damage stats. A Genshin Artifact Calculator can help you balance ER with other offensive stats.
7. Crit Rate to Crit DMG Ratio: For most DPS characters, a 1:2 ratio of Crit Rate to Crit DMG (e.g., 70% CR / 140% CD) is considered optimal for consistent damage. Your Genshin Artifact Calculator weights should reflect this balance.
8. Diminishing Returns: While not directly calculated by the score, it’s important to remember that stacking too much of one stat can lead to diminishing returns. For example, having 100% Crit Rate might mean further Crit Rate rolls are less valuable than other stats.

Frequently Asked Questions (FAQ)

Q: What is a good score for an artifact using this Genshin Artifact Calculator?

A: There isn’t a universal “good” score, as it heavily depends on the weights you set for your specific character. For a main DPS, a score above 50-60 (with standard Crit/ATK% weights) is generally considered very good, while 70+ is exceptional. For support artifacts, scores can vary widely based on EM or ER priority. The best approach is to compare artifacts for the same slot using consistent weights.

Q: How do I know what weights to use for my character in the Genshin Artifact Calculator?

A: Research your character’s scaling and role. For example, a main DPS like Xiao prioritizes Crit and ATK%. A support like Bennett prioritizes Energy Recharge and HP. Websites like KQM (Keqing Mains) provide detailed guides and recommended stat priorities for most characters, which can inform your weight choices for the Genshin Artifact Calculator.

Q: Why is Crit Rate weighted higher than Crit DMG in the default settings?

A: This is based on the common “Crit Value” (CV) metric, where Crit Rate is typically multiplied by 2 because 1% Crit Rate is generally considered as valuable as 2% Crit DMG for overall damage consistency. This 1:2 ratio is often optimal for maximizing average damage output.

Q: Should I always use the artifact with the highest score from the Genshin Artifact Calculator?

A: Not always. While a higher score usually indicates a better artifact, you must consider your overall build. Sometimes, an artifact with a slightly lower score might be necessary to complete a crucial 4-piece set bonus, reach an Energy Recharge breakpoint, or balance your Crit Ratio. Use the Genshin Artifact Calculator as a guide, not an absolute rule.

Q: Are flat stats (Flat ATK, HP, DEF) ever good?

A: Generally, percentage-based stats are superior to flat stats because they scale with your character’s base stats. However, flat stats can have minor value, especially for characters with very low base stats or if you get many rolls into them. For most builds, their weights in the Genshin Artifact Calculator should remain low.

Q: Can this Genshin Artifact Calculator predict future rolls?

A: No, this specific Genshin Artifact Calculator evaluates the current state of an artifact. Predicting future rolls would require a different type of calculator that simulates RNG, which is beyond the scope of this tool. This calculator helps you assess what you currently have.

Q: What if my artifact has a main stat that’s also a substat (e.g., ATK% main stat and ATK% substat)?

A: This Genshin Artifact Calculator focuses solely on the *substats* of an artifact. The main stat is assumed to be chosen correctly for the character and slot. You should only input the values that appear under the “Substats” section of your artifact in-game.

Q: How does Elemental Mastery work with this Genshin Artifact Calculator?

A: Elemental Mastery (EM) is weighted based on its importance for reaction damage. For characters like Nahida, Kazuha, or Sucrose, who heavily rely on amplifying elemental reactions (e.g., Spread, Aggravate, Vaporize, Melt, Swirl), you would assign a high weight to EM. For pure Anemo/Geo DPS or physical damage dealers, EM might have a very low weight.
