In Genshin Impact, there are a multitude of diverse and varied characters that are highlight in the summons system. Venti has for example its own limited-time banner but it will end soon and have to be replaced by another. This is where Klee is introduced, this little girl who likes to play with the explosion (a little dangerous, no?).
If you want to see what it gives in terms of gameplay in a dungeon, here is a video that may interest you.
As with Venti, we don't know at this time if these characters will be added to the permanent banner or if there will be any characters left on the limited banners. We will have to wait and see how miHoYo will organize itself on this.
