The 7 Elements and Elemental Reactions in Genshin Impact

• Pyro — applies Vaporize-ready heat, a component of Vaporize and Melt.
• Hydro — applies Wet, a component of Vaporize and Frozen.
• Electro — applies Electro-Charged setup, a component of Overloaded and Superconduct.
• Cryo — a component of Frozen (with Hydro) and Melt (with Pyro); breaking Frozen can stun in an area.
• Anemo — triggers Swirl when it touches another element, pulling/pushing enemies and spreading that element to nearby targets.
• Geo — triggers Crystallize, forming a shield carrying that element.
• Dendro — the most recently added element, powering its own family of reactions (Quicken, Bloom, Aggravate, Spread, Burgeon, Hyperbloom) when combined with Hydro/Electro/Pyro.

11 core reactions: Burning, Wet, Vaporize, Bloom-precursor (Grow), Electro-Charged, Frozen, Overloaded, Melt, Swirl, Superconduct, Crystallize.

6 Dendro-related reactions: Bloom, Quicken, Aggravate, Spread, Burgeon, Hyperbloom.

3 Lunar reactions (newer, tied to the "Moonsign" mechanic): Lunar-Charged, Lunar-Bloom, Lunar-Crystallize — for this group we deliberately don't publish a specific damage formula: the publisher hasn't released one, and we refuse to make one up or copy a community estimate just to fill the gap.

An Elemental Reaction needs 2 different elements touching the same target, happening in combat, instantly. Elemental Resonance is the opposite — it needs 2 characters sharing the same element in the same party, auto-activating for the whole fight without ever touching an enemy. Per the verified data in our database: Pyro Resonance raises the whole party's ATK; Hydro Resonance improves healing effectiveness; Cryo Resonance raises CRIT Rate against Cryo/Frozen targets; Electro Resonance helps regenerate Energy; Anemo Resonance lowers stamina consumption and shortens Elemental Skill cooldowns; Geo Resonance raises RES and damage while shielded by Crystallize. Dendro isn't part of this classic resonance group — its resonance is more complex and tied to its own Dendro-reaction family, so this article doesn't go deep on it to avoid getting it wrong.
