Is there a lot of grinding?

genshin impact= farming simulator, ngl but is pretty rewarding

There is so much grinding, like you have to fight a lot of monster while exploring the map, when I first played it I thought it would be like SAO but I was wrong, I still enjoy the game it just takes to much time to complete task and unlocking map, the character as-well take to much time on grinding up and MAXING them out, so make sure you have an empty calendar before you start playing. You might get hooked on Genshin.

Alot of grinding it can get hard if you dont have that much time and want to upgrade a charecter at a high rank

Yes there is a lot of grinding. The game is so broad you need to search in Google for hidden stuffs
