What is Base ATK in Genshin Impact?

Base ATK is the sum of your character's natural attack (gained via leveling up) and your weapon's primary attack stat. This is the ONLY number that ATK% bonuses multiply. Artifact flat attack and buffs like Bennett do NOT increase your Base ATK.

What is the difference between ATK% and Flat ATK?

ATK% multiplies your Base ATK (Character + Weapon). Flat ATK is added at the end of the calculation. For example, a 5-star Feather provides 311 Flat ATK, which is added after all percentage calculations are done.

Why does Bennett give so much ATK?

Bennett's Elemental Burst provides an "Attack Bonus" based on HIS Base ATK. Since this is a flat addition that can exceed 1000 ATK, it significantly boosts your "Total ATK" without requiring you to build ATK% on your main DPS.

Is there diminishing returns on ATK?

Not literally, but there is an opportunity cost. Since damage is [ATK × (1 + DMG Bonus) × (1 + CRIT Multiplier)], stacking too much ATK while neglecting DMG% or CRIT will result in lower total output than a balanced build.

What is the "Ideal" amount of ATK?

Generally, you want your "Green" number (Bonus ATK) to be roughly 110% to 120% of your "White" number (Base ATK) before prioritizing other stats. If you use Bennett, you can often afford to have less ATK on your gear.

Does ATK affect Elemental Reactions?

ATK affects Vaporize and Melt (Amping reactions) because they scale off the underlying hit. It does NOT affect transformative reactions like Overloaded, Swirl, or Bloom, which scale based on character level and Elemental Mastery.

Which artifacts provide the most ATK?

The Feather main stat provides 311 Flat ATK. The Sands main stat can provide 46.6% ATK%. Set bonuses like Gladiator's (2pc) or Shimenawa's (2pc) provide 18% ATK%.

Does weapon rarity affect ATK?

Yes. 5-star weapons have significantly higher Base ATK (usually 608–741) compared to 4-star weapons (usually 454–565). This makes every ATK% roll on your artifacts much more valuable.

What character stats scale with ATK?

Most characters use ATK for their damage scaling. However, some characters like Zhongli (HP), Noelle (DEF), and Albedo (DEF) scale primarily with other stats for their main abilities.

How does Noblesse Oblige affect ATK?

The 4-piece Noblesse Oblige set provides a 20% ATK buff to the entire team. This 20% multiplies each character's own Base ATK.

Interpreting Your Result

Bonus ATK < 50% of Base: Very low ATK investment. 50%–100%: Moderate investment. 110%–130%: The "Sweet Spot" for balanced builds. >150%: High ATK (potentially over-invested if CRIT is low).

✓ Do's

•Compare your "Green" number to your "White" number in the character screen to see your efficiency.
•Use high Base ATK weapons on characters who will receive lots of ATK% buffs.
•Remember that Bennett and Thrilling Tales of Dragon Slayers provide massive ATK for free, potentially freeing up your Sands artifact for EM or ER.
•Level your character to 80/90 and your weapon to 90/90 to maximize your Base ATK foundation.

✗ Don'ts

•Don't ignore ATK% just because CRIT looks cooler—crit hits are only as big as the base they multiply.
•Don't use an ATK% Sands if your character scales better with HP (Hu Tao) or DEF (Itto) for their damage.
•Don't forget about "External" ATK buffs like Noblesse Oblige and Tenacity of the Millelith when planning your build.
•Don't over-level your character to 90 just for ATK% if you are low on resources; the weapon level is usually more important.

How It Works

The Genshin Impact Attack Damage Calculator is an essential tool for understanding the foundation of your character's power. While CRIT and Elemental bonuses are important, they all multiply your "Total ATK". This calculator breaks down the calculation into its core components—Base ATK, Percentage bonuses, and Flat additions—allowing you to see exactly how much each new artifact or buff contributes to your final stat.

Understanding the Inputs

Character Base ATK: The white number on your stat screen (character part). Weapon Base ATK: The white number on your stat screen (weapon part). ATK%: Total percentage bonus from all artifacts, weapons, and passives. Flat ATK: Sum of all flat bonuses like the Feather or Bennett's buff.

Formula Used

Total ATK = [Base ATK × (1 + ATK%)] + Flat ATK Base ATK = Character Base ATK + Weapon Base ATK. ATK% = Sum of all ATK% bonuses from artifacts, weapon sub-stats, and passives. Flat ATK = Sum of all flat bonuses (e.g., Feather main stat, Bennett burst, Noblesse set). Example: Character (300) + Weapon (600) = 900 Base ATK. With 100% ATK% and 311 Flat ATK: Total ATK = [900 × (1 + 1.00)] + 311 = 2111.

Real Calculation Examples

1900 Base, 75% ATK%, 311 Flat: Total = (900 * 1.75) + 311 = 1886.
21000 Base, 120% ATK%, 1000 Flat (Bennett): Total = (1000 * 2.2) + 1000 = 3200.
3800 Base, 50% ATK%, 0 Flat: Total = (800 * 1.5) = 1200.

The Comprehensive Guide

Genshin Impact Attack Damage Calculator: The Comprehensive Guide to Total ATK Calculation

In the mathematical engine of Teyvat, every massive crit and every elemental explosion starts with a humble foundation: Attack (ATK). While many players focus on flashy secondary stats, your Total ATK is the primary multiplier that determines the baseline of your power. This Genshin Impact Attack Damage Calculator is designed to help you decode your stat sheet, optimize your artifact sub-stats, and master the art of team-wide attack buffs.

The Structure of ATK: Understanding the "White" and "Green" Numbers

If you open your character attributes screen in Genshin Impact, your ATK stat is presented as two numbers: a white number (Base ATK) and a green number (Bonus ATK). Understanding the difference between these two is the single most important skill for theorycrafting.

1. The Foundation: Base ATK (The White Number)

Your Base ATK is the absolute baseline of your power. It is the only part of your attack that is multiplied by the percentage bonuses (ATK%) found on your artifacts and weapons. Base ATK consists only of:

Character natural ATK: This increases automatically as you level up and ascend.
Weapon Base ATK: The raw attack value of your equipped weapon.

Crucially, nothing else contributes to your Base ATK. Not the flat attack on your Feather artifact, not Bennett's buff, and not your artifact sub-stats. This is why a weapon with a high base ATK (like the 741 Base ATK of the Song of Broken Pines) is valueable—it raises the ceiling of every ATK% roll you have.

2. The Multiplier: ATK% Bonuses (The Green Number Part A)

Percentage bonuses take your Base ATK and grow it. These bonuses are summed together before being applied to the base. If you have a 46.6% ATK Sands and two sub-stats of 5% each, your total ATK% bonus is 56.6%. This is multiplied by your white number to form the first part of your green number.

3. The Flat Addition: Flat ATK (The Green Number Part B)

Flat ATK is added after all percentage calculations are complete. It does not scale with your ATK% artifacts. The most common sources include:

Artifact Feather: A 5-star Feather provides 311 Flat ATK at level 20.
Sub-stats: Minor flat additions found on artifacts.
Character Specific Buffs: Bennett's Elemental Burst provides an "Attack Bonus" which is added as a flat number to your character based on Bennett's own Base ATK.

The Master ATK Formula

To calculate your Total ATK from scratch, you can use the following formula, which is the same logic used by our calculator:

Total ATK = [ (Char Base + Weapon Base) × (1 + ATK%) ] + Flat ATK

Finding the Sweet Spot: The "Golden Ratio" of ATK

Is there such a thing as too much ATK? In terms of raw damage, no—more is always better. However, in terms of optimal distribution, yes. Every developer-designed "stat budget" on an artifact could have been spent on CRIT Rate or CRIT DMG instead. Theorycrafters generally recommend that your Bonus ATK (the green number) should be roughly 110% to 125% of your Base ATK (the white number).

If you are significantly above 125% Bonus ATK, your build is likely "ATK-saturated," and you would see much higher damage by trading some of those ATK% rolls for CRIT stats. This is particularly true if you play in teams with heavy ATK buffers like Bennett or Kujou Sara.

The Power of the Support: External ATK Buffs Explained

One of the most misunderstood aspects of Genshin Impact is how support characters influence your main DPS's attack stat. Let's look at the "Big Three" sources of external ATK:

1. Bennett: The Universal Multiplier

Bennett's burst provides a flat ATK bonus to any character standing in his circle. This bonus scales only with Bennett's Base ATK (Character + Weapon). This is why building ATK% artifacts on Bennett is a common mistake; they do not increase the buff he gives his team. A high-base weapon like the Aquila Favonia or Skyward Blade is the best way to maximize Bennett's impact.

2. Weapon-Based Buffs: TToDS and Wolf's Gravestone

Items like Thrilling Tales of Dragon Slayers (TToDS) provide a massive 48% ATK% buff to the next character swapped in. This 48% is multiplied by the main DPS's Base ATK, essentially giving them a free ATK% Sands. Similarly, Wolf's Gravestone can provide up to 100% total ATK% to all party members under certain conditions.

3. Artifact Set Buffs: Noblesse and Tenacity

Set bonuses like Noblesse Oblige (+20% ATK on burst) and Tenacity of the Millelith (+20% ATK on skill hit) provide teamwide multipliers. These are additive with your main DPS's own ATK% stat. If your Diluc already has 100% ATK% from gear, a Noblesse buff moves him to 120% ATK%.

ATK Scaling for Specific Elements: Vaporize vs. Transformative

The value of ATK varies depending on the type of damage you are dealing:

Amping Reactions (Vaporize, Melt): ATK is extremely valuable because these reactions multiply the total damage of the hit, which includes your ATK scaling.
Transformative Reactions (Overload, Swirl, Bloom): These reactions ignore your ATK entirely. They scale only with your character level and Elemental Mastery. If you are building a full-swirl Kazuha, you can leave your ATK stat at the bare minimum.
Aggravate and Spread (Quicken): These reactions add a flat damage bonus to your hit, which is added alongside your ATK scaling before CRIT is applied. This makes ATK slightly less critical than for Vaporize, but still very important.

Diminishing Returns: The Opportunity Cost of Stacking ATK

While adding 100 ATK always adds the same "raw" damage amount, the percentage increase to your total output shrinks as your total moves higher. If you have 1,000 ATK, adding 100 ATK is a 10% damage increase. If you have 3,000 ATK, adding 100 ATK is only a 3.3% increase. At this high end, you are almost always better off investing in Elemental DMG Bonus% (Goblins) or CRIT stats, which multiply your already massive ATK pool.

Strategic Tip: When to Use an ATK% Sands

Generally, an ATK% Sands is the standard for 90% of damage dealers. However, you should consider alternatives in these cases:

With Bennett: If you are constantly inside Bennett's burst, your ATK is already so high that an Elemental Mastery Sands (for reactions) or ER Sands (for burst uptime) will often produce higher total damage.
Non-ATK Scalers: Characters like Itto, Noelle, Albedo (DEF) and Hu Tao, Yelan, Nilou (HP) gain the majority of their damage from other stats. For them, ATK% is a "dead stat."
High-Base Weapons: If you have a weapon with 674+ Base ATK, ATK% sub-stats are so efficient that you might not even need an ATK% Sands to reach the Golden Ratio.

Common Mistakes and Misconceptions

Neglecting Weapon Levels: Leveling a weapon from 80 to 90 is often the single most efficient way to gain ATK because it increases your Base, which then multiplies everything else. It is worth more than weeks of artifact farming.

Over-stacking ATK in Diluc/Xiangling Builds: These characters often benefit more from EM than extra ATK because they trigger Vaporize so consistently.

Buying into the "Crit is Everything" Hype: Many players sacrifice 500 ATK just to gain 10% more Crit DMG. Use this calculator to see if that trade-off actually makes you weaker. High multipliers on a low base equals low damage.

Advanced Usage of the ATK Damage Calculator

Don't just calculate your current stats. Use this tool for What-If Analysis:

Weapon Comparison: See how a 4-star weapon with ATK% sub-stat compares to a 5-star weapon with higher base but lower percentage.
Buff Optimization: Calculate your total ATK while factoring in Thrilling Tales and Noblesse to see if you've overshot the Golden Ratio.
Resin Priority: Determine if your next goal should be leveling your character, leveling your weapon, or farming more artifact sub-stats.

Usage of This Calculator

Who Should Use This?

Genshin Impact players trying to understand their character's stat sheet, people optimizing Bennett and Thrilling Tales rotations, and anyone transitioning from early-game "ATK stacking" to late-game "Multi-multiplier optimization".

Limitations

Calculates raw ATK stats. It does not calculate final damage (which requires accounting for multipliers, enemy defense, and resistance). It is a foundation tool.

Real-World Examples

The Bennett Boost

Scenario: A character has 800 Base ATK and 1200 Bonus ATK (2000 Total). Bennett adds 1000 Flat ATK.

Outcome: Total ATK becomes 3000. This is a 50% total damage increase just from one character's skill.

Weapon Swap Impact

Scenario: Swapping a 454 Base ATK weapon (4-star) for a 674 Base ATK weapon (5-star) on a character with +150% ATK from artifacts.

Outcome: Base ATK increases by 220. The final ATK increases by 220 * (1 + 1.5) = 550. High base weapons have a compound effect.

Summary

Attack Damage is the fundamental building block of damage in Genshin Impact. By understanding how your Base ATK interacts with percentage and flat bonuses, you can build a solid foundation for your CRIT and Elemental multipliers to work upon. Use this calculator to ensure your character has enough raw power to make those critical hits truly meaningful.
