Some Genshin Impact characters have brilliant passive talents that can be immensely helpful while playing in the world of Teyvat. For instance, at least one character from every region has a passive talent that shows their region's local specialties on the Genshin Impact map, which makes the material collecting journey far easier. There are also characters that can save or obtain more resources, like units that get more reward when going on expeditions, or those that reduce the cost of upgrading or forging items.
