Elemental Resonances in Genshin Impact are based on the elements represented in a party. For example, Protective Canopy is four unique elements in the party.
Elemental Resonances are always active in Genshin Impact as long as the player either has two characters of the same element or has four random characters with different elements in the party. Of course, this also means that different Elemental Resonance effects are based on which lineup the player has.
It’s worth noting that this is strictly based on the number of elements in the party. So in Protective Canopy’s case, it doesn’t matter if it’s four random four-star units or four random five-star units. All that would matter is that four different elements are being represented in the party.
If that’s achieved, then the player gets All Elemental RES +15% and Physical RES +15% for all Genshin Impact characters in the party.
Genshin Impact: Protective Canopy and all other Elemental Resonances explained
Other than Protective Canopy, all remaining Elemental Resonances in Genshin Impact require just two members of the same element to be in the party lineup. This means that players can have up to two Elemental Resonances active at all times.
If players go for Protective Canopy, then it’s only possible to have that Elemental Resonance active. To check a user’s Elemental Resonances, they can go to the party lineup screen and click on “Elemental Resonance” on the top right.
