What is a Genshin Impact Artifact Optimizer Calculator?

A Genshin Impact Artifact Optimizer Calculator is a specialized tool designed to help players assess the quality and potential of their artifact pieces. In Genshin Impact, artifacts are crucial equipment that provide significant stat bonuses and set effects to characters. However, their stats and substats are randomized, making it a challenge to find optimal gear. This calculator helps quantify how “good” an artifact is by analyzing its substats, estimating the number of beneficial rolls it has received, and assigning an overall optimization score. It aims to eliminate the guesswork involved in artifact farming and management.

Who should use it:

• New Players: To understand the basics of artifact stats and identify pieces worth investing in early on.
• Mid-Game Players: To refine their character builds, optimize substat rolls, and decide which artifacts to upgrade.
• End-Game Players: To meticulously min-max character performance, compare near-identical artifacts, and identify pieces with exceptional substat distributions.
• Anyone frustrated with RNG: When the artifact lottery feels overwhelming, this tool provides a data-driven approach.

Common misconceptions:

• “It tells me the EXACT best artifact”: While it scores potential, the “best” artifact also depends on the character’s specific needs, team composition, and playstyle. This tool scores the piece itself.
• “It guarantees a perfect artifact”: The calculator works with the stats you input. It assesses the *current* value and potential based on known roll ranges.
• “All substats are equally valuable”: The calculator assigns value based on common build priorities, but certain substats might be more or less valuable for a specific character or role.

Genshin Impact Artifact Optimizer Formula and Mathematical Explanation

The core idea behind the Genshin Impact Artifact Optimizer is to quantify the “goodness” of an artifact based on the substats it possesses and the number of times those substats have been upgraded. We aim to calculate an ‘Effective Roll Count’ and an ‘Optimization Score’.

1. Identifying Substat Rolls:

Artifacts start with 3 or 4 substats at level 0. For every 4 levels (4, 8, 12, 16, 20), a substat is upgraded (or a new one is added if the artifact has fewer than 4). A level 20 artifact typically has 4 substats, meaning it has received 4 upgrade rolls in addition to its initial substats.

2. Substat Roll Values:

Each substat type has a range of possible values it can gain per roll. For a 5-star artifact, these rolls can be low, mid, or high. For example, Crit Rate% can roll between 1.9% and 2.7%.

3. Calculating Effective Rolls:

This is the most complex part. We need to estimate how many “good” rolls an artifact has. A simplified approach:

1. Determine the total number of rolls the artifact has received based on its level and initial substat count. (Level 0 with 4 substats = 4 rolls, Level 4 with 4 substats = 4 rolls, Level 8 with 4 substats = 5 rolls, …, Level 20 with 4 substats = 8 rolls).
2. For each substat, determine if its current value falls within a “desirable” range. We often consider “high-end” rolls to be more valuable. A common method is to assume each initial substat is at least a “low roll” and each subsequent upgrade adds more value.
3. A more practical approach: Calculate the minimum and maximum possible total value for each substat based on the number of rolls. Then, calculate the artifact’s current total value as a percentage of the maximum possible value for that substat. This gives a “roll quality” score per substat.
4. Summing these “roll quality” scores across all substats, weighted by their importance for a specific build, gives the optimization score.

Simplified Formula for this Calculator (Optimization Score):

Score = Σ (Value of Substat X / Max Possible Value for Substat X per roll * Weight of Substat X)

Where ‘Max Possible Value’ is the highest possible single roll value for that substat type, and ‘Weight’ is determined by the artifact type and common character builds.

For this calculator, we simplify further by calculating the total number of *effective* rolls. An effective roll is approximated by dividing the current substat value by the average roll value. We then sum these effective rolls.

Variables Table:

Variable	Meaning	Unit	Typical Range (5-Star)
Artifact Level	The current level of the artifact piece.	Level	0 – 20
Substat Type	The specific stat provided by a substat (e.g., Crit Rate%, ATK).	Stat Name	HP, ATK, EM, ER, Crit Rate, Crit DMG, DEF
Substat Value	The current numerical value of a substat.	% or Flat Value	Varies (see ranges below)
Roll Range (Min/Max)	The minimum and maximum value a substat can gain per upgrade roll.	% or Flat Value	See Table Above
Total Substat Rolls	The total number of times any substat has been upgraded. (Max 8 for 5-star at Lv 20)	Count	4 – 8
Effective Rolls	An estimated count of how many “good” substat upgrades the artifact has received. Calculated as current value / average roll value.	Count	Typically 4-10+
Optimization Score	A composite score representing the overall quality of the artifact’s substats. (Not directly calculated here but implied by Effective Rolls).	Score Unit	Higher is better

Note: The calculator primarily focuses on estimating ‘Effective Rolls’ as a proxy for the Optimization Score. The main stats and artifact type influence *which* substats are considered good and are factored into the interpretation.

Practical Examples (Real-World Use Cases)

Example 1: A Potentially Great Crit Substat Artifact

Scenario: You found a 5-star Circlet of Logos with Crit DMG% as the main stat. It has HP%, ATK%, Crit Rate%, and DEF% as substats.

Inputs:

• Artifact Type: Circlet of Logos
• Main Stat: Crit DMG%
• Rarity: 5-Star
• Artifact Level: 20
• Substats: HP (300 flat), ATK (30 flat), Crit Rate (7.0%), DEF (7.0%)

Calculator Output:

• Primary Result (Optimization Score): ~8.2 (This is an estimation based on effective rolls)
• Intermediate Value 1 (Total Substat Rolls): 8
• Intermediate Value 2 (Effective Rolls): 8.2
• Intermediate Value 3 (Potential Rolls Remaining): 0 (at level 20)

Interpretation: This artifact has Crit Rate, which is highly desirable for a Crit DMG Circlet. The Crit Rate is 7.0%, which is roughly 2 good rolls (average roll ~3.5% for 5-star). The HP and ATK are flat values, which are less useful for most characters compared to percentage scaling. DEF% is decent for DEF-scaling characters. With 8 total rolls into 4 substats, this artifact has received average to above-average upgrades, especially in Crit Rate. An effective roll count of 8.2 suggests it’s a solid piece, likely worth investing in.

Example 2: An Average Sands of Eon for an ATK Scaling Character

Scenario: You have a 5-star Sands of Eon with ATK% main stat. It started with HP, DEF, Crit Rate, and EM.

Inputs:

• Artifact Type: Sands of Eon
• Main Stat: ATK%
• Rarity: 5-Star
• Artifact Level: 16
• Substats: HP (4.1%), DEF (5.8%), Crit Rate (3.9%), Elemental Mastery (31)

Calculator Output:

• Primary Result (Optimization Score): ~6.5
• Intermediate Value 1 (Total Substat Rolls): 7 (Level 16 = 7 rolls)
• Intermediate Value 2 (Effective Rolls): 6.5
• Intermediate Value 3 (Potential Rolls Remaining): 1 (at level 20)

Interpretation: This Sands has ATK%, which is good for many characters. The substats include Crit Rate (3.9%, approx 1 roll), HP (4.1%, approx 1 roll), DEF (5.8%, approx 1-2 rolls), and EM (31, approx 1 roll). The total effective rolls are around 6.5. This indicates a decent but not outstanding artifact. The Crit Rate roll is on the lower end. Since it’s only level 16, it has one more potential upgrade. If that final roll lands on Crit Rate or ATK% (if it were a substat), the artifact’s value would increase significantly. As it stands, it’s a usable piece but might be replaceable by one with better substat rolls.

How to Use This Genshin Impact Artifact Optimizer Calculator

Using the Genshin Impact Artifact Optimizer is straightforward. Follow these steps to get an accurate assessment of your artifact’s potential:

1. Select Artifact Type: Choose the slot the artifact belongs to (Flower, Plume, Sands, Goblet, Circlet). This helps contextualize the main stats available.
2. Select Main Stat: Choose the primary stat the artifact possesses. This is crucial as certain main stats are universally good (like ATK% Sands) while others are slot-specific (like Crit Rate% Circlet).
3. Choose Rarity: Select whether the artifact is 5-Star or 4-Star. This impacts the range of substat values.
4. Enter Artifact Level: Input the current level of the artifact (0 to 20). This determines how many substat upgrades it has received.
5. Input Substats: For each unique substat present on the artifact, select its type from the dropdown and enter its current numerical value.
• Important: Do NOT enter duplicate substat types (e.g., two Crit Rate% entries).
• Enter values exactly as they appear in-game (e.g., 7.0 for 7.0%, 31 for 31 EM).
• The calculator will automatically track the number of unique substats entered (up to 4).
6. Click “Calculate Value”: Once all information is entered, press the button.

How to Read Results:

• Primary Highlighted Result (Optimization Score): This is a general score indicating the artifact’s quality. Higher scores mean more beneficial substat rolls. A score above 7-8 is generally considered good for 5-star artifacts.
• Total Substat Rolls: This shows the total number of times substats have been upgraded (initial + rolls from levels 4, 8, 12, 16, 20).
• Effective Rolls: This is the key metric. It estimates how many “good” or “high-quality” rolls the artifact has received, calculated by dividing the current substat value by the average roll value for that stat. Higher effective rolls mean a better artifact.
• Potential Rolls Remaining: If the artifact is not yet level 20, this indicates how many more times its substats *could* be upgraded.

Decision-Making Guidance:

• High Effective Rolls (e.g., 8+): The artifact is excellent and likely worth leveling to 20 if it isn’t already.
• Medium Effective Rolls (e.g., 5-7): A decent artifact. Consider leveling it, especially if the substats are highly desirable for a specific character.
• Low Effective Rolls (e.g., <5): The artifact is likely not worth significant investment unless it has an extremely rare combination of needed stats (like EM on a specific support).
• Prioritize Character Needs: Always consider if the substats align with the character you’re building. Crit Rate/DMG are generally high priority, followed by ATK%, ER, EM, HP%, DEF% depending on the character.

Key Factors That Affect Genshin Impact Artifact Results

Several factors influence the perceived value and the calculated score of an artifact. Understanding these helps in interpreting the calculator’s output more effectively:

1. Character Build Priorities: The most crucial factor. A substat like Energy Recharge might be amazing for a support but detrimental for a main DPS. Crit Rate and Crit DMG are often universally desired for damage dealers, but their relative importance can shift. This calculator assigns a general value, but your specific character’s needs override it.
2. Main Stat Relevance: An artifact’s main stat is fixed and often defines its primary role. An ATK% Sands is generally good, but an ATK% Sands on a character who scales primarily with HP (like Hu Tao) or DEF (like Itto) is less optimal. The calculator notes the main stat but doesn’t heavily penalize common ones unless they are extremely niche.
3. Substat Duplication: Artifacts cannot roll into the same substat multiple times during upgrades. If an artifact starts with Crit Rate and rolls Crit Rate again, that’s two rolls contributing to Crit Rate. The calculator assumes unique substats were entered. Duplicates *within the initial 4 substats* are not possible.
4. Substat Roll Quality (Low vs. High Rolls): Each substat upgrade adds a value within a specific range. A “high roll” adds more value than a “low roll.” This calculator approximates effective rolls by dividing the current value by the average roll value, implicitly assuming a mix of roll qualities. An artifact with only high rolls will feel much better in practice than its calculated score might suggest.
5. Artifact Rarity and Level: 5-star artifacts have higher potential substat values and more upgrade chances (up to 8 rolls at level 20) compared to 4-star artifacts (up to 5 rolls). The calculator accounts for rarity and level to determine total rolls and uses 5-star ranges. A 4-star artifact with good substats can still be valuable, especially early game.
6. Set Bonuses: While this calculator focuses on individual artifact pieces, the actual value is heavily influenced by the 2-piece or 4-piece set bonuses they contribute to. An artifact with slightly weaker substats might be essential if it completes a powerful set bonus.
7. Synergy with Weapons: A character’s weapon can provide significant amounts of stats (e.g., Crit Rate from Mistsplitter Reforged). This might reduce the need for that substat on artifacts, allowing focus on others like Crit DMG or ATK%.

Frequently Asked Questions (FAQ)

What is the difference between a 4-star and 5-star artifact’s potential?

5-star artifacts can start with 4 substats and receive up to 5 upgrades (total 8 substat rolls at level 20), and their individual roll values are higher. 4-star artifacts start with 3 or 4 substats and receive up to 4 upgrades (total 7 rolls at level 20, or fewer if only 3 initial substats), with lower roll values. This means 5-stars have a much higher ceiling for optimization.

Can I input flat stats like HP and ATK?

Yes, the calculator supports both percentage-based and flat substats (HP, ATK, DEF). However, for most damage-focused characters, percentage-based stats are generally more valuable at higher investment levels.

What if my artifact has fewer than 4 substats initially?

Artifacts at level 0 can have 3 or 4 substats. 5-star artifacts typically start with 4 substats unless they have flat HP or flat ATK as an initial substat, in which case they may have 3. The calculator assumes the standard number of rolls based on level. For precise calculations, you’d need to know the exact number of initial substats and upgrades.

How do I know the exact roll values for my substats?

The calculator uses average roll values. In-game, each roll adds a value within a range (e.g., Crit Rate rolls between 1.9%-2.7%). You can manually track your artifact’s upgrades to see if they were low, mid, or high rolls, but this calculator provides a good estimate based on the total value.

Is the ‘Optimization Score’ the same as the artifact’s damage contribution?

Not directly. The score is a measure of substat quality and quantity. The actual damage contribution depends heavily on the character’s base stats, weapon, level, talent levels, enemy resistances, and team buffs. This score helps you identify potentially strong pieces to build upon.

What are the most valuable substats for main DPS characters?

Generally, Crit Rate% and Crit DMG% are top priorities, followed by ATK%. For some characters, Elemental Mastery (especially for reaction-based DPS) or Energy Recharge% might be crucial. The ideal balance depends on the character’s multipliers, scaling, and kit.

Should I prioritize a 4-piece set bonus or better substats on off-piece artifacts?

This is a common dilemma. Generally, a 4-piece set bonus provides significant value. However, if your “off-piece” (an artifact from a different set) has exceptionally good substats and a useful main stat, it can sometimes outperform a piece from the correct set that has poor substats. Aim for the best combination, but don’t sacrifice too much substat quality solely for the set bonus.

How often should I re-evaluate my artifacts?

Artifact farming is an ongoing process. Re-evaluate your artifacts whenever you get a new piece that seems promising, or when you start building a new character. Regularly reviewing your inventory using tools like this calculator can help you identify hidden gems and optimize your resin spending.
