What is Elemental Mastery?

Improves Elemental Reactions

Elemental Mastery is an attribute that amplifies the Elemental Reactions. The higher your Elemental Mastery, the more powerful the reactions will be!

Make sure to raise your Elemental Mastery for your Main DPS characters that rely on Elemental Reactions like Vaporize or Melt to maximize their damage output!

List of Elemental Reactions

Effects of Elemental Mastery

Elemental Mastery can buff all elements and their reactions. Most elemental reactions are offensive, and Elemental Mastery simply adds more damage to the reaction damage. On the other hand, Geo reactions increases the Shield's effectivity.

List of All Effects of Elemental Mastery

Elemental Reaction	Elemental Mastery Effect
Crystallize	Increases the shield's effect from the element reacted.
Swirl	Increases the Swirled Element's AoE damage.

Superconduct	Increases the Cryo AoE reaction damage.
Frozen	Has no effect unless a character triggers Shatter.
Shattered	Increases the Physical damage dealt when Frozen enemies are hit by blunt attack.
Quicken	Creates the Quicken Aura for seven seconds. When either Dendro or Electro is applied to a Quickened enemy, it will increase the damage by the reacting element.
Aggravate	When Electro is applied to a Quickened enemy, it will increase that instance of Electro damage based on the character's Elemental Mastery.
Spread	When Dendro is applied to a Quickened enemy, it will increase that instance of Dendro damage based on the character's Elemental Mastery.
Bloom	Creates Dendro Cores. Dendro Cores stay in the field until an Element triggers the Core. Otherwise, it will explode deal minor AoE Dendro damage based on the triggerer's Elemental Mastery.
Burgeon	A Pyro Character that triggers a Dendro Core will make it burst, dealing AoE Dendro damage based on the Pyro character's Elemental Mastery.
Hyperbloom	An Electro Character that triggers a Dendro Core will home a Sprawling Shot to an Enemy, dealing a small AoE of Dendro damage based on the Electro character's Elemental Mastery.
Burning	Continuously deals Pyro damage until it wears off. Deals minor single-target Pyro damage based on their Elemental Mastery.

Update 1.6 Changes

The following changes to Elemental Mastery was applied in Version 1.6.

Version 1.6 Elemental Mastery Changes
・ Increases the damage caused by major reactions (Electro-Charged, Superconduct, Overloaded, Shatter, and Swirl) when a character reaches level 60 and above ・Increase the Base Shield DMG Absorption for shields generated by Crystallize reactions ・Increases the DMG Bonus provided by Elemental Mastery for major reactions. (Refer to the attributes panel in-game for the exact DMG Bonus amount.)

Who Activates Elemental Mastery?

The One Who Applies the 2nd Element

The character that applied the 2nd element is the one whose Elemental Mastery is taken into account. You should upgrade your Main DPS's Elemental Mastery especially those that have Pyro, Hydro, or Cryo element to improve their damage output.

Sub-DPS and Supports generally do not need Elemental Mastery, as they are the ones applying the 1st Element. Instead, they benefit more from Energy Recharge to output more Elemental Bursts.

Best Characters to Use Elemental Mastery

Characters to Build Elemental Mastery

Best Characters for Elemental Mastery Stat
Hu Tao	• Hu Tao in tandem with Xingqiu can deal consistent Vaporize. It is recommended to have some Elemental Mastery on her artifact substats.
Kazuha	• Kazuha transforms Elemental Mastery into Elemental DMG Bonus for the teammate based on the Swirled element. Stacking Elemental Mastery will also increase his own personal damage from Swirl.
Nahida	• Nahida provides high Elemental Mastery bonus to an active party member in the duration of her Elemental Burst. It is also recommended to stack EM stats for Nahida as each point of her EM surpassing 200 grants 0.1% DMG bonus and 0.03% CRIT Rate for her Elemental Skill.
Alhaitham	• Alhaitham's abilities scale with Elemental Mastery along with ATK. He thrives with Elemental Reactions involving Bloom or Quicken, which makes him dependent on the stat.
Sucrose	• Sucrose provides Elemental Mastery to her teammates based on her own Elemental Mastery. Stacking Elemental Mastery on her Artifacts provides a huge damage increase to your Main DPS.
Tartaglia	• Tartaglia's Elemental Burst scaling is huge. It is recommended to have some Elemental Mastery on him if you are planning to trigger Vaporize.
Venti	• Venti's Elemental Burst infuses an Element and constantly Swirls it to all enemies trapped inside the vortex. Having Elemental Mastery weapons such as The Stringless is recommended.
Xiangling	• Xiangling can consistently Vaporize or Melt when she's teamed up with fast Elemental appliers like Tartaglia or Xingqiu for Hydro.

Elemental Mastery either as main stat or sub stat on artifacts or weapons can greatly increase their damage output or their support capabilities. It is recommended to build some Elemental Mastery on their stats to maximize their effects.

How much Elemental Mastery is good?

500~1000 for Elemental Mastery-Stacking Characters

For characters that primarily stacks Elemental Mastery, such as Anemo or Dendro Supports or Sub-DPS like Sucrose, Kazuha, or Nahida, you need as much Elemental Mastery as possible. A minimum of 500 and 1000 Elemental Mastery at max is the best for such characters.

100> for Melt or Vaporize Reactors

For characters that thrives from reactions like Melt or Vaporize, an Elemental Mastery count of around 100 is best for such characters. If you can't reach this number yet, you can make up by stacking more CRIT Rate and DMG as possible.

Elemental Mastery vs. ATK

Elemental Mastery Alone is Not Enough

Elemental Mastery increases the damage multiplier on the initial damage you deal to enemies when causing an elemental reaction. This means raising only Elemental Mastery won't deal high damage if you don't increase your character's ATK stat.

Balance Elemental Mastery and ATK/Crit

Do take note that Elemental Mastery has diminishing returns if you do not build enough ATK or Crit Rate/Crit DMG on them, so make sure you are also building these important stats!

A healthy build is to find a middle ground between raising Elemental Mastery and other stats like Crit DMG and ATK, as most Elemental Skills scale with the latter.

How to Increase Elemental Mastery

You can raise your Elemental Mastery by equipping artifacts with Elemental Mastery stat. Some artifacts have Elemental Mastery as their main stat, such as the Sands of Eon, Goblet of Eonothem, and the Circlet of Logos. You can also receive Elemental Mastery by rolling on substats.
