The seven elements in Genshin Impact are important for battle, but knowing all of the combinations of Elemental Reaction and Resonance is a must for building powerful teams.Our guide explains all the Elemental Reactions and Resonance effects in Genshin Impact.Elemental ResonanceHaving two of the same element type on a party will activate Elemental Resonance, giving your team a special buff. The buffs are as follows:Fervent Flames (Pyro): Affected byCryofor 40% less time. Increases ATK by 25%.Enduring Rock (Geo): Increases shield strength by 15%. Additionally, characters protected by a shield will have the following special characteristics: DMG dealt increased by 15%, dealing DMG to enemies will decrease theirGeoRES by 20% for 15s.Sprawling Greenery (Dendro): Elemental Mastery increased by 50. After triggering Burning, Quicken, or Bloom reactions, all nearby party members gain 30 Elemental Mastery for 6s. After triggering Aggravate, Spread, Hyperbloom, or Burgeon reactions, all nearby party members gain 20 Elemental Mastery for 6s. The durations of the aforementioned effects will be counted independently.Impetuous Winds (Anemo): Decreases Stamina Consumption by 15%. Increases Movement SPD by 10%. Shortens Skill Cooldown (CD) by 5%.Shattering Ice (Cryo): Affected byElectrofor 40% less time. Increases CRIT Rate against enemies that are Frozen or affected byCryoby 15%.Soothing Waters (Hydro): Affected byPyrofor 40% less time. Increases max HP by 25%.High Voltage (Electro): Affected byHydrofor 40% less time. Superconduct, Overloaded, Electro-Charged, Quicken, Aggravate, or Hyperbloom have a 100% chance to generate an Electro Elemental Particle (CD: 5s).Protective Canopy (Any four unique elements): All Elemental RES +15%, Physical RES +15%.Youll likely want to take advantage of these bonuses. Tons of teams with main Pyro DPS will use Bennett or Xianglings Pyro affinity to get an ATK bonus, whereas Zhongli and Itto mains may rely more on the increased shield strength.Elemental ReactionsWhen two elements are applied to an enemy, they will typically react. Not every combination will have a reaction, but you should definitely be using the ones that are available to your advantage in combat. The reactions are as follows:Frozen (Cryo + Hydro): Frozen beings are rendered immobile, but also become rock-hard.Vaporize (Pyro + Hydro): The Pyro or Hydro attack that triggers Vaporize deals increased DMG.Electro-Charged (Electro + Hydro): Electro-Charged continuously deals Electro DMG until it wears off. Electricity intermittently arcs off of Electro-Charged beings, shocking Hydro-affected opponents nearby.Overloaded (Pyro + Electro): The resulting explosion deals AoE Pyro DMG, and tears effortlessly through otherwise sturdy objects.Superconduct (Cryo + Electro): Superconduct deals AoE Cryo DMG and significantly decreases Physical RES for the affected being.Burning (Pyro + Dendro): Continuously deals Pyro DMG until it wears off.Swirl (Anemo + Cryo/Electro/Hydro/Pyro): Swirl can deal elemental DMG, affect beings, and generate further Elemental Reactions.Melt (Cryo + Pyro): The Pyro or Cryo attack that triggers Melt deals increased DMG.Crystalize (Geo + Cryo/Electro/Hydro/Pyro): This type of elemental reaction can generate corresponding Elemental Shards and provide your character with various Elemental Shields.Bloom (Dendro + Hydro): Bloom causes Dendro Cores to fall off the enemy and onto the floor. When Dendro Cores are hit with Pyro, this causes Burgeon, which does AoE Dendro damage. When Dendro Cores are hit with Electro, the cores become homing Sprawling Shots. Cores left on the ground will explode and do AoE Dendro damage.Quicken (Dendro + Electro): When Quickened, Electro attacks activate Aggravate and do more damage. Further Dendro attacks to a Quickened enemy activate Spread, which increases Dendro damage to the enemy.
