Yes. Weapon ATK can affect Elemental Skill and Elemental Burst damage in Genshin Impact when the ability scales with ATK.
Your weapon’s Base ATK contributes to your character’s Base ATK, which is then used when calculating ATK-based damage. This means upgrading your weapon can increase much more than Normal Attack damage.
However, not every character scales primarily with ATK. Some abilities use HP, DEF, Elemental Mastery, or other mechanics instead, so the importance of Weapon ATK depends on the character and Talent.
Does Weapon ATK Increase Elemental Skill Damage?
For an ATK-scaling Elemental Skill, yes.
A common misconception is that the ATK shown on a weapon only affects Normal Attacks. It does not work that way.
Your character’s Base ATK includes:
- The character’s own Base ATK
- The equipped weapon’s Base ATK
ATK% bonuses are then calculated using that Base ATK, while flat ATK is added separately.
So if an Elemental Skill scales with ATK, increasing your weapon’s Base ATK can increase the ATK used by that Skill.
This is one reason weapon levels can remain important even for characters who spend very little time using Normal Attacks.
Does Weapon ATK Increase Elemental Burst Damage?
Yes, if the Elemental Burst scales with ATK.
The same basic principle applies.
If a Burst uses your character’s ATK to calculate its damage, the Base ATK provided by the weapon contributes to the character’s ATK and therefore can affect the Burst’s damage.
For example, an off-field character may enter combat, use an Elemental Burst, and immediately leave the field.
That character may rarely perform a Normal Attack, but their weapon can still be important because the Burst itself may use their ATK.
Weapon ATK Does Not Mean Normal Attack Damage
This distinction is important.
The ATK stat and Normal Attack damage are not the same thing.
ATK is a character stat that many different abilities can use when calculating damage.
Normal Attacks are simply one type of attack.
Depending on the character, ATK may contribute to:
- Normal Attacks
- Charged Attacks
- Plunging Attacks
- Elemental Skills
- Elemental Bursts
- Certain Talent effects
So a character does not need to swing their weapon for Weapon ATK to be useful.
What Is Base ATK?
Base ATK is particularly important when understanding weapons.
In simplified form, your character’s Base ATK comes from:
Character Base ATK + Weapon Base ATK
Percentage-based ATK bonuses then scale from this base value. KQM’s current damage documentation similarly defines ATK using the character’s ATK and weapon ATK as the base before percentage and flat bonuses are applied.
This is why two weapons with different Base ATK values can produce different final ATK values even before considering their passive effects and secondary stats.
What About the Weapon’s ATK% Stat?
Do not confuse Weapon Base ATK with an ATK% secondary stat.
They are different.
Weapon Base ATK contributes directly to your character’s Base ATK.
An ATK% bonus instead increases ATK based on that Base ATK. Percentage stat increases use the character’s base value rather than simply multiplying every additional flat stat.
That distinction becomes important when comparing weapons.
A weapon with higher Base ATK is not automatically better than one with lower Base ATK because the second weapon may offer a more useful secondary stat or passive.
Does This Mean Higher Weapon ATK Is Always Better?
No.
This is where weapon comparisons become more complicated.
A weapon can provide:
- Base ATK
- CRIT Rate
- CRIT DMG
- ATK%
- Energy Recharge
- Elemental Mastery
- HP%
- DEF%
- Damage bonuses
- Character-specific passive effects
A weapon with lower Base ATK may still perform better if its secondary stat and passive fit the character significantly better.
This is also why a suitable 4-star weapon can sometimes be more useful for a particular build than an unsuitable 5-star weapon.
Are There Characters Whose Skills Do Not Mainly Scale With ATK?
Yes.
Not every Talent calculates damage from ATK.
Depending on the character, an ability may scale with:
- Max HP
- DEF
- Elemental Mastery
- Multiple stats
- A character-specific mechanic
The current general damage formula explicitly distinguishes ATK-, DEF-, HP-, and EM-scaling Talents rather than treating every Talent as ATK-based.
For these characters, simply choosing the weapon with the highest Base ATK may provide much less benefit than choosing a weapon whose secondary stat or passive supports the character’s actual scaling.
How Can You Tell What a Skill Scales With?
Check the character’s Talent description and Talent attributes.
The percentages shown for a Talent tell you its scaling, but you also need to understand which stat that scaling uses.
For many traditional ATK-scaling abilities, the listed percentage is applied using ATK. Other characters may explicitly use HP, DEF, Elemental Mastery, or additional mechanics.
If you are unsure, do not assume that a weapon with more ATK automatically gives the largest damage increase.
Look at the character’s Talent scaling first.
Should You Upgrade Weapons for Skill and Burst Characters?
Usually, yes when the character benefits from the weapon’s Base ATK and other stats.
Weapon levels can improve:
- Base ATK
- The weapon’s secondary stat
- The effectiveness of an ATK-scaling build
But how valuable those upgrades are depends on the character.
An ATK-scaling damage dealer may benefit significantly from additional Weapon ATK, while an HP- or DEF-focused character may care more about the weapon’s secondary stat and passive.
That is why weapon investment should be based on the character’s actual scaling rather than simply whether they use Normal Attacks.
Weapon ATK vs Talent Level: Which Matters More?
They improve different parts of the damage calculation.
Weapon upgrades can increase the stats used by an ability, while Talent levels usually increase the Talent’s damage multiplier.
For an ATK-scaling Skill or Burst, both can therefore matter.
If your weapon is severely underleveled, increasing its level may provide a noticeable improvement. If the weapon is already appropriately leveled but the Talent remains low, upgrading the Talent may become the more important next step.
The most effective upgrade depends on the current state of the build.
Why Can Damage Still Be Low With a Strong Weapon?
Weapon ATK is only one part of Genshin Impact’s damage system.
Damage can also depend on:
- Talent levels
- CRIT Rate and CRIT DMG
- Elemental DMG Bonus
- Artifact main stats
- Artifact substats
- Elemental reactions
- Enemy DEF and RES
- Character buffs
- Team synergy
- Energy requirements
- Weapon passive effects
So equipping a high-ATK weapon does not automatically create a strong build.

Quick Answer
Does Weapon ATK affect Skills?
Yes, when the Skill scales with ATK.
Does Weapon ATK affect Bursts?
Yes, when the Burst scales with ATK.
Does Weapon ATK only affect Normal Attacks?
No.
Does every character need high Weapon ATK?
No. Some characters scale with HP, DEF, Elemental Mastery, or other mechanics.
Is the weapon with the highest Base ATK always the recommended weapon?
No. Secondary stats and weapon passives can be more important depending on the character.
Final Advice
Do not judge a weapon only by how large its ATK number looks.
First check what your character’s important Talents actually scale with. If their Skill or Burst scales with ATK, Weapon ATK can contribute to that damage even if the character rarely performs Normal Attacks.
If the character instead relies heavily on HP, DEF, Elemental Mastery, or another mechanic, the weapon’s secondary stat and passive may be more important than simply choosing the highest Base ATK available.
Understanding that distinction makes weapon comparisons much easier—and can prevent you from investing resources into a weapon simply because its ATK number looks higher.
