Genshin Character Build Calculator

Optimize your Genshin Impact character stats and artifact substats.

Character & Artifact Stat Calculator

Build Summary

Formula Explanation:

Total ATK is calculated as Base ATK * (1 + Total ATK% from artifacts).
Total Crit Rate is Base Crit Rate + (Crit Rate Substat Rolls * average Crit Rate per roll).
Total Crit Damage is Base Crit Damage + (Crit Damage Substat Rolls * average Crit Damage per roll).
Effective Crit Value (ECV) aims to quantify the synergy between Crit Rate and Crit Damage. A common formula is ECV = Total Crit Rate * Total Crit Damage. We present ECV normalized by a target Crit Rate of 75% and Crit DMG of 150% for comparison, but the raw product is also informative.

What is Genshin Character Build Optimization?

Genshin Character Build Optimization refers to the strategic process of selecting and upgrading weapons, artifacts, talents, and team compositions to maximize a character’s effectiveness in combat. The goal is to create a synergistic build that allows a character to perform their intended role (DPS, support, healer) at their highest potential. This involves understanding character scaling, enemy weaknesses, and the intricate mechanics of artifact substats and main stats. It’s a core aspect of the late-game experience in Genshin Impact, where players strive for the most powerful and efficient character setups.

Who should use this calculator: Any Genshin Impact player looking to understand how their artifact substats contribute to their character’s overall damage potential. This includes players aiming to:

• Assess the quality of their artifact rolls.
• Compare different artifact farming outcomes.
• Understand the impact of specific substats like ATK%, Crit Rate, and Crit DMG.
• Set realistic goals for their character builds.

Common misconceptions: A common misconception is that simply having high Crit Damage is enough for a strong build. In reality, Crit Rate and Crit Damage work together synergistically. Without sufficient Crit Rate, high Crit Damage has a low chance of activating. Another misconception is that every substat roll must be perfect; optimization is about balancing strong rolls and achieving target benchmarks rather than perfection.

Genshin Character Build Calculator Formula and Mathematical Explanation

Our Genshin Character Build Calculator focuses on quantifying the impact of artifact substats on core combat stats: Attack, Crit Rate, and Crit Damage. The process involves calculating the total value of these stats based on the character’s base values, weapon, and the distribution of substat upgrades.

Step-by-step derivation:

1. Calculate Total Attack: The character’s total Attack stat is derived from their Base Attack (from character and weapon) and any flat Attack or Attack Percentage gained from artifacts. For simplicity in this calculator, we focus on Attack Percentage (ATK%) from artifact substats.
   
   Formula: Total ATK = Base Attack * (1 + (Total ATK% Rolls * Average ATK% per roll))
2. Calculate Total Crit Rate: This is the character’s innate Crit Rate plus any Crit Rate gained from artifact substats.
   
   Formula: Total Crit Rate = Base Crit Rate + (Crit Rate Substat Rolls * Average Crit Rate per roll)
3. Calculate Total Crit Damage: This is the character’s innate Crit Damage plus any Crit Damage gained from artifact substats.
   
   Formula: Total Crit Damage = Base Crit Damage + (Crit Damage Substat Rolls * Average Crit Damage per roll)
4. Calculate Effective Crit Value (ECV): This metric attempts to provide a single number representing the combined effectiveness of Crit Rate and Crit Damage. A widely accepted simplified formula is the product of the two stats.
   
   Formula: ECV = Total Crit Rate * Total Crit Damage

Variable explanations:

• Base Attack: The sum of the Attack stat from the character’s base level and their equipped weapon.
• Base Crit Rate: The character’s inherent Crit Rate without any artifact or weapon bonuses.
• Base Crit Damage: The character’s inherent Crit Damage without any artifact or weapon bonuses.
• Number of Artifact Substats: Indicates how many unique substats an artifact starts with (typically 3 for 4-star artifacts at level 0, or 4 for 5-star artifacts at level 0).
• Total Substat Rolls: The total number of times any substat on the artifacts has been upgraded (occurs every 4 artifact levels).
• ATK% Substat Rolls: The count of how many of the Total Substat Rolls landed on the ATK% substat.
• Crit Rate Substat Rolls: The count of how many of the Total Substat Rolls landed on the Crit Rate substat.
• Crit Damage Substat Rolls: The count of how many of the Total Substat Rolls landed on the Crit Damage substat.

Variables Table:

Variable	Meaning	Unit	Typical Range (Substat Rolls)
Base Attack	Attack from character & weapon	ATK	400 – 700+
Base Crit Rate	Innate Crit Rate	%	5% – 33.1% (Character dependent)
Base Crit Damage	Innate Crit Damage	%	50% – 88.4% (Character dependent)
Artifact Substats	Initial number of substats	Count	3 or 4
Total Substat Rolls	Total upgrades applied	Count	0 – ~20
ATK% Substat Rolls	Rolls into ATK%	Count	0 – Total Substat Rolls
Crit Rate Substat Rolls	Rolls into Crit Rate	Count	0 – Total Substat Rolls
Crit Damage Substat Rolls	Rolls into Crit Damage	Count	0 – Total Substat Rolls
Average ATK% per roll	Average value added	%	~4.1%
Average Crit Rate per roll	Average value added	%	~3.9%
Average Crit Damage per roll	Average value added	%	~7.8%

Practical Examples (Real-World Use Cases)

Let’s illustrate with two common scenarios:

Example 1: Well-Rolled Artifacts on a DPS Character

Consider a character like Hu Tao with her signature weapon Staff of Homa.

• Inputs:
  • Base Attack: 718 (Hu Tao Lv 90 Base ATK 334 + Staff of Homa Lv 90 Base ATK 608, assuming 100 base ATK from Sands Main Stat for calculation purposes) -> Let’s use 718 for simplicity.
  • Base Crit Rate: 5%
  • Base Crit Damage: 88.4%
  • Artifact Substats: 4
  • Total Substat Rolls: 16 (4 artifacts * 4 rolls each)
  • ATK% Substat Rolls: 2
  • Crit Rate Substat Rolls: 6
  • Crit Damage Substat Rolls: 8
• Calculation:
  • Total ATK = 718 * (1 + (2 * 0.041)) = 718 * 1.082 ≈ 776 ATK
  • Total Crit Rate = 5% + (6 * 3.9%) = 5% + 23.4% = 28.4%
  • Total Crit Damage = 88.4% + (8 * 7.8%) = 88.4% + 62.4% = 150.8%
  • ECV = 28.4% * 150.8% ≈ 4284
• Output:
  • Total ATK: 776
  • Total Crit Rate: 28.4%
  • Total Crit Damage: 150.8%
  • Effective Crit Value (ECV): 4284
• Interpretation: This represents a strong build. The crit stats are well-balanced, leaning slightly more towards Crit Damage due to the character’s high base CD. The low ATK% substat rolls are compensated by the high Crit Rate and Crit Damage rolls, resulting in a respectable ECV.

Example 2: Suboptimal Rolls on a Support Character

Consider a support character like Xingqiu focusing on ER, but with some offensive substats.

• Inputs:
  • Base Attack: 455 (Xingqiu Lv 90 Base ATK 205 + Sacrificial Sword Lv 90 Base ATK 300)
  • Base Crit Rate: 5%
  • Base Crit Damage: 50%
  • Artifact Substats: 4
  • Total Substat Rolls: 12 (4 artifacts * 3 rolls each, assuming some artifacts haven’t hit max level)
  • ATK% Substat Rolls: 3
  • Crit Rate Substat Rolls: 2
  • Crit Damage Substat Rolls: 3
• Calculation:
  • Total ATK = 455 * (1 + (3 * 0.041)) = 455 * 1.123 ≈ 511 ATK
  • Total Crit Rate = 5% + (2 * 3.9%) = 5% + 7.8% = 12.8%
  • Total Crit Damage = 50% + (3 * 7.8%) = 50% + 23.4% = 73.4%
  • ECV = 12.8% * 73.4% ≈ 939.5
• Output:
  • Total ATK: 511
  • Total Crit Rate: 12.8%
  • Total Crit Damage: 73.4%
  • Effective Crit Value (ECV): 939.5
• Interpretation: This build has very low offensive stats. The low number of rolls into Crit stats and the moderate amount into ATK% lead to a significantly lower ECV. This indicates that focusing on offensive stats for this particular artifact set wasn’t optimal, and perhaps more Energy Recharge or HP substats would be prioritized for Xingqiu’s support role.

How to Use This Genshin Character Build Calculator

Using the Genshin Character Build Calculator is straightforward. Follow these steps to assess your character’s stats:

1. Input Base Stats: Enter your character’s Base Attack (from character + weapon). Input their innate Base Crit Rate and Base Crit Damage.
2. Define Artifact Substat Quality: Specify the number of substats your artifacts typically have at level 0 (usually 4 for 5-star items). Then, input the Total Substat Rolls across all your artifacts for the character. This is a crucial number representing how many times any substat has been upgraded.
3. Allocate Substat Rolls: Enter how many of those Total Substat Rolls landed specifically on ATK%, Crit Rate, and Crit Damage.
4. Calculate: Click the “Calculate Build” button.

How to read results:

• Total ATK: Shows your character’s final Attack value after artifact ATK% bonuses.
• Total Crit Rate & Crit Damage: Displays your character’s final Crit Rate and Crit Damage after artifact substat bonuses. Aim for a 1:2 ratio (e.g., 70% Crit Rate / 140% Crit Damage) as a general guideline.
• Effective Crit Value (ECV): A single number representing the synergy between Crit Rate and Crit Damage. Higher is generally better for DPS characters, but always consider the 1:2 ratio.
• Intermediate Values & Assumptions: Provide context on how the ECV was derived and the average values used for substat rolls.
• Table & Chart: Visually break down the contribution of base stats versus substats and show the distribution of your rolls.

Decision-making guidance: Use the results to decide if your current artifact rolls are satisfactory. If your ECV is low or your Crit Rate/Damage ratio is skewed, you might need to farm for better artifacts or adjust your expectations for the character’s performance.

Key Factors That Affect Genshin Character Build Results

Several factors significantly influence the effectiveness of a Genshin Impact character build, and by extension, the results of any calculation tool:

1. Character & Weapon Base Stats: The foundation of your build. Characters and weapons with higher Base Attack provide a larger canvas for ATK% bonuses to amplify. Similarly, characters with innate Crit Rate or Crit Damage will start with an advantage.
2. Artifact Main Stats: While this calculator focuses on substats, the main stats of artifacts (e.g., ATK% Sands vs. Elemental Mastery Sands, Crit Rate/Damage Circlet) are paramount. Choosing the correct main stat is often more impactful than substats.
3. Substat Roll Distribution: As demonstrated, where your substat rolls land is critical. Rolling into desirable stats like Crit Rate/Damage for a DPS, or Energy Recharge for a support, vastly improves effectiveness. Bad rolls into undesirable stats (like DEF% on an ATK-scaling character) reduce efficiency.
4. Artifact Set Bonuses: Many artifact sets provide significant buffs (e.g., 4-piece Crimson Witch of Flames for Pyro DPS, 4-piece Noblesse Oblige for support buffs). These bonuses are not factored into this basic stat calculator but are essential for optimal builds.
5. Talent Levels: Character talents directly increase the effectiveness of their skills, bursts, and normal attacks. A high talent level can significantly boost damage output, independent of artifact stats.
6. Team Synergies and Buffs: A character’s performance is heavily influenced by their teammates. Elemental reactions (Vaporize, Melt), buffs from supports (Bennett’s ATK buff), and debuffs on enemies can dramatically increase damage numbers, often exceeding the gains from pure stat optimization.
7. Enemy Resistances and Defenses: Enemies have varying resistances to different elements and physical damage. Exploiting elemental synergies and overcoming high resistances are key to maximizing damage in challenging content like the Spiral Abyss.
8. Crit Rate/Crit Damage Ratio: Maintaining a balanced ratio is crucial. A common target is 1:2 (e.g., 70% Crit Rate / 140% Crit Damage). Significantly deviating from this can lead to inefficient damage output.

Frequently Asked Questions (FAQ)

What are the average substat roll values in Genshin Impact?

While values can vary slightly, typical substat increments are:

• Crit Rate: ~3.9%
• Crit Damage: ~7.8%
• ATK%: ~4.1%
• Flat ATK: ~11-15
• HP/DEF: ~4-6% or ~200-230
• Energy Recharge/EM: ~4.4% / ~16-20

This calculator uses the common crit and ATK% values.

How many substat rolls can an artifact have?

A 4-star artifact can start with 3 or 4 substats. A 5-star artifact always starts with 4 substats. Each artifact gains a new substat or upgrades an existing one every 4 levels (at levels 0, 4, 8, 12, 16, 20).

What is the ideal Crit Rate to Crit Damage ratio?

The most commonly recommended ratio is 1:2. For example, 70% Crit Rate and 140% Crit Damage. This ensures a good balance, maximizing the chance of landing critical hits while also having a significant damage multiplier. Going too far above 1:2 often yields diminishing returns compared to improving other stats.

Does Base Attack include the Sands main stat?

For this calculator’s purpose, “Base Attack” refers to the Attack value derived directly from the character’s base stats and their weapon’s base stats. The Sands artifact main stat (which can be ATK% or flat ATK) is accounted for separately by the artifact substat calculations or adds to the final Total ATK.

My character has low Crit Rate, should I prioritize Crit Rate or Crit Damage substats?

If your Crit Rate is significantly below your Crit Damage (i.e., far from the 1:2 ratio), prioritizing Crit Rate substats is generally more beneficial until you reach a more balanced state. A 1:2 ratio ensures consistency in critical hits.

How does Elemental DMG Bonus affect calculations?

This calculator focuses purely on raw Attack, Crit Rate, and Crit Damage. Elemental DMG Bonus goblets and set bonuses significantly multiply the final damage, but they are additive with each other and multiplicative with other damage multipliers. They are not directly calculated here but are crucial for overall damage output.

What about stats like Elemental Mastery or Flat Attack?

Elemental Mastery (EM) is crucial for reaction-based damage (Vaporize, Melt, Overload) and is highly valuable for specific characters and teams. Flat Attack substats add a fixed amount of ATK. This calculator simplifies by focusing on ATK% and crit stats, as they are universally important for most damage dealers.

Can this calculator be used for supports?

Yes, but with a different focus. While this calculator provides offensive stats, supports often prioritize Energy Recharge, HP%, or DEF% depending on their role and scaling. However, understanding their offensive substat distribution can still be useful if they contribute to damage.
