Elemental Reaction is a basic combat mechanic in Genshin Impact that occurs when two Elements are applied together, triggering a combination of effects. See how each Elemental Reactions work, chart for all reactions, and the best characters for it in this guide!

Elemental Reaction Mechanics

Two Elements Trigger a Reaction

An Elemental Reaction occurs when an entity affected with an Element is triggered by another. For example, a Cryo-affected enemy will cause Melt when hit by a Pyro attack. If the same Element was applied, the status will simply prolong.

Some reactions are more effective based on which Element was applied first. For example, Vaporize is 2x as effective if Hydro is the triggerer to an enemy with a Pyro status. Otherwise, a Pyro attack on a Hydro-afflicted enemy will only be 1.5x effective.

More Effective with Elemental Mastery

Elemental Mastery is a character stat that increases the effectiveness or damage of your Elemental Reactions. You can get more Elemental Mastery by equipping them with weapons possessing this substat, levelling your artifacts, or activating character buffs.

Note that the reactor, or the character that triggers the reaction, is the only entity affected by the amplification effects of Elemental Mastery, which means that characters who simply apply the Element will not take Elemental Mastery into account.

Elemental Reaction List and Effects

Depending on the Elemental combination, each reactions will have different effects.

Here is the list of all Elemental Reactions in Genshin Impact:

Name	Element	Effect
Swirl	➡︎	Deals AoE damage based on the reacted Element, then spreads that element to nearby enemies.
Crystallize	➡︎	Creates a crystal shard that you can pick up, which provides a shield effective against the element that created the reaction.
Vaporize	⬅︎➡︎	An instance of damage dealt will be multiplied based on the reacting Element.
Melt	⬅︎➡︎	An instance of damage dealt will be multiplied based on the reacting Element.
Electro-Charged	⬅︎➡︎	Target takes Electro damage over time.
Frozen	⬅︎➡︎	Target is temporarily frozen in place and stopping all enemy actions except Bosses.
Shatter	⬅︎➡︎	When a Frozen enemy is hit by Geo, or blunt attacks from a Claymore, Plunging or other heavy attacks, the enemy will Shatter, dealing Physical damage and removing the Frozen status.
Overloaded	⬅︎➡︎	Target explodes, knocking back enemies in proximity and deals AoE Pyro damage.
Superconduct	⬅︎➡︎	AoE Cryo damage occurs and decreases Physical resistance.
Burning	⬅︎➡︎	Deals Pyro damage over time.
Bloom	⬅︎➡︎	Creates a Dendro Core. Dendro Cores explode when too many are made or after a set durtion.
Burgeon	➡︎	Pyro damage detones a Dendro Core, dealing AoE Dendro damage.
Hyperbloom	➡︎	Electro damage detones a Dendro Core, transforming it into a Sprawling Shot that deals Dendro damage.
Quicken	⬅︎➡︎	Afflicts the enemy with Quicken. This enables follow-up catalyze reactions.
Aggravate	➡︎	Deals increased Electro damage to a Quickened enemy.
Spread	➡︎	Deals increased Dendro damage to a Quickened enemy.

Swirl

Elemental Status	Reactor
Pyro Hydro Cryo Electro	⬅︎ Anemo
Effect
・Current Elemental Status spreads and remains on the enemy. ・Anemo cannot be applied as an Elemental Status.

The Swirl elemental reaction activates when Anemo is used on an enemy that has Pyro, Hydro, Electro, or Cryo already applied to it. When a Swirl reaction occurs, the element reacted will spread to nearby enemies as AoE damage and apply that element to them as well.

For example, when Hilichurls and Cryo Slimes are standing on water, hitting the Cryo Slime with Anemo will spread Cryo to all nearby enemies, freezing the Hilichurls due to the Frozen reaction!

The only way to increase Swirl DMG is by increasing the Elemental Mastery of the character triggering the reaction.

Crystallize

Elemental Status	Reactor
Pyro Hydro Cryo Electro	⬅︎ Geo
Effect
・Creates a Crystallize Shard, which provides an elemental shield to the active character. ・Shield created is more effective against the Element it reacted from. ・Status is removed until the element is depleted.

Crystallize activates when a Geo attack hits an enemy that has Pyro, Hydro, Electro, or Cryo applied to it. When a Crystallize reaction occurs, the applied element on the enemy will disappear and a pickable elemental shield shard corresponding to the element will spawn.

The shield spawned will protect the player based on Geo character's Elemental Mastery. However, it will be more efficient in protecting against attacks corresponding to the element of the shield.

Vaporize

Elemental Status	Reactor
Hydro Pyro	⬅︎ Pyro (x1.5) ⬅︎ Hydro (x2)
Effect
・Increases an instance of Pyro or Hydro damage dealt multiplied based on which Element was used second. ・Elemental Mastery increases the damage dealt before the damage is multiplied. ・Status is removed until the element is depleted.

Vaporize activates when Pyro comes into contact with Hydro and vice versa. When Vaporize occurs, the target will take increased multiplicative damage and their previously applied element will be removed.

Pyro Cryo	⬅︎ Cryo (x1.5) ⬅︎ Pyro (x2)
Effect
・Increases an instance of Cryo or Pyro damage dealt multiplied based on which Element was used second. ・Elemental Mastery increases the damage dealt before the damage is multiplied. ・Status is removed until the element is depleted.

Electro-Charged

Elemental Status	Reactor
Electro Hydro	⬅︎ Hydro ⬅︎ Electro
Effect
・Deals Electro damage over time and affects enemies affected with Hydro. ・Electro and Hydro statuses both remain briefly on the original enemy, and can trigger two effects at once. ・Electro status will be used and removed first when the DoT ends or when an additional reaction is triggered.

Electro-Charged occurs when Hydro or Electro come into contact with each other, which deals Electro damage over time. When an Electro-Charged reaction activates, nearby targets with Hydro status will also take the effect, but will not receive the Electro-Charged status.

When it's raining, the Wet status will be applied to everything in the area, making it easy to cause an Electro-Charged reaction. Increasing the Elemental Mastery of the character triggering Electro-Charged will increase the damage over time caused by the reaction!

▲ Return to Reactions Table ▲

Frozen

Elemental Status	Reactor
Cryo Hydro	⬅︎ Hydro ⬅︎ Cryo
Effect
・Immobilizes freezable enemies except Bosses or Cryo-immune enemies. ・Cryo status will remain until a different Element is applied. ・Frozen enemies hit by a strong blunt attack such as Claymore hits will Shatter the enemy, which removes the Frozen status and deals damage based on the shatterer's Elemental Mastery.

Frozen occurs when Hydro and Cryo come into contact with one another. When Frozen activates, the target will be unable to move. Frozen can be set off against enemies in water or rain.

Frozen enemies can be shattered, which deals Physical Damage. Examples of attacks that can shatter frozen enemies are Claymores, Plunging Attacks and Geo Attacks. Increasing the Elemental Mastery of the character triggering the shatter will cause it to deal more damage.

Superconduct occurs when Electro and Cryo come into contact. When a Superconduct reaction activates, AoE Cryo damage will hit nearby enemies and will lower their physical resistance for 12 seconds.

The damage of Superconduct can be increased by the amount of Elemental Mastery the character who is triggering the reaction has. The amount of the physical resistance reduced will always be a fixed amount of about -40%.

All subsequent creations of such cores will immediately detonate the oldest Bloom core. ・Hydro is removed from the enemy, but the Dendro status may remain until the max usage of its aura is depleted.

Hydro and Dendro mixing together will trigger Bloom and create a Dendro Core. Dendro cores can interact with Pyro, which will make the seed explode, or with Electro, which turns it into a homing missile. Dendro Cores can explode on their own after a set time or if too many are on the field.
