HoYoVerse released a short trailer for the upcoming Sumeru region and Dendro element in Genshin Impact. Sumeru will be part of Version 3.0, which will go live after the next update, Version 2.8. While Dendro is an existing element in the game, Sumeru will be the first time players will be able to use it. As well, Dendro will react with elements other than Pyro.
The Sumeru trailer features the Genshin Impact development team discussing how it implemented and chose to design Dendro in the game. According to the trailer, the concepts ‘catalysis, wisdom, and life’ were key in how the team designed the elemental reactions, level designs, and environmental puzzles. An example of a Sumeru environmental mechanic seems to be a mushroom that the Traveler can jump on like a trampoline.
Version 3.0 will introduce the Bloom and Catalyze reactions. Bloom is Hydro and Dendro, while Catalyze is Electro and Dendro. The video does not explain what the reactions do. However, it does mention that you will be able to use elements to alter states of Dendro objects and monsters. Depending on the state, Dendro monsters will have different attacks, as well as drop different items.
Genshin Impact is readily available on PS4, PS5, Windows PC, and mobile devices. A Nintendo Switch version is in the work. Version 2.8 will launch on July 13, 2022, with Sumeru appearing in Genshin Impact 3.0. There is no confirmed release date as of yet for Version 3.0.
