Recently, when surfing at the NGA, I saw such a post: Take off the ice on your hands, what are the advantages and disadvantages of Ganyu Guoshou and Kaia Rosalia?

Removing ice from your hands is generally for two purposes:
One: Hit the elemental reaction
Two: Permafrost staining
And based on these two purposes, which characters have the most efficient and best effect of taking off their hands on ice?
The scope is not large enough: Rosalia, Kaia
Rosalia's main means of getting off the ice on her hand is her own big move, but in fact, due to the effect of six lives to reduce resistance, Rosalia is more suitable for teaming up with the physical big C - Youla, and the ice efficiency of her own big move is not bad, but the range of big moves is still not large enough.
The miner leader Kaizige's ice-going means are also mainly based on the big move of getting rid of his hands, but it is still the problem: the range is too small, and it needs to be close to the monster to go to the ice, and when facing the scattered monsters, the efficiency of the ice is really not enough to see.
Same door group: Gan Yu, Shen He
Although most of Ganyu is cultivated as the main C, Ganyu's ability to hang ice in the background can be said to be second to none, and the four-life effect adds an additional role to Ganyu's big move in addition to hanging ice (although I can't afford it).
Gan Yu's fellow disciple Shen He is the ice special assistant of the side head and tail, and the actual test is bigger than Rosalia's big move.
Diffusion groups: Sugar, Manyo, Wendy
This part of the character itself does not have the ability to go to ice, but these three characters as long as they play the Permafrost, they will definitely bring one, their role is not limited to the Permafrost, as long as they play the elemental reaction, these three can be competent, and their own big moves have a certain function (monster gathering, injury increase).
Of course, these are my personal views, it is inevitable that some bias (Chongyun has not yet talked about it), if there are different opinions, welcome to leave your views in the comment area!
