Genshin Impact 4-star character strength and mechanics are uneven, and some have been found no news just after running as a 5-star escort, but some characters are still very popular with players since the start of the server. In fact, when planning the design of 4-star characters, it has been divided into 4 levels according to the allocation of remaining resources: 1st level: 90 levels, 2nd level 80 levels, 3rd level 50 levels, and 4th level 1 is not given.
A 4-star dark horse character worthy of upgrading to level 90: Shinobu Kuki
The rise of the Sumeru grass system, the only strongest grass team, Kuki Shinobu is the most critical role, seamless thunder trigger + milk, plus low-cost training, Jiuqi Shinobu is the largest dark horse 4-star character since the opening of the service, as long as the novice has Kuki Shinobi, with low-cost Collei or Yaoyao, the basic low world level can be imprisoned in the holy relic secret realm. Due to the mastery of the grass system, Kuki Shinobu is the most worthy character to upgrade to the full level, and it is also the only one.
The second level of 80 levels: In fact, most of these roles are functional roles, and the gap between 80 or 90 levels is not large, in view of the optimal allocation of resources, 99% of the occasions and teams have been met by breaking through level 80. For example, Xingqiu, Bennett, Xiangling, Jiaming, Faruzan, Yun Jin, Kujou Sara, etc., this kind of character, especially the character with 6 lives qualitatively changed, no 6 lives are simply put in the warehouse, but they can form a mainstream team, and they have to go up to level 80. There are also princesses, Yaoyao, Sucrose, Diona, Beidou, maids, Rosaria, Goro, Yanfei and so on.
The third level is up and down level 50: You can upgrade to level 50, but you don't want to waste resources too much, this kind of role is generally mostly a server role, and there is no role to open up the wasteland in the early days. In fact, these characters are about level 50, and you can know their strength, or you can be eliminated by 5-star characters. For example, Chongyun, Razor, Ningguang, Kaeya, Sayu, Barbara, and many more. It's not that I don't want to upgrade them, it's just that other characters are more cost-effective, more damage and feel.
I don't want to give the fourth level 1: Compared with other characters, this kind of role is basically dispensable, and it will be wasted if you raise it, or the 4-star characters that came out in the later stage have been killed by the current 5-star characters, and even some new 4-star characters are not as good as some old 4-star characters. For example: Black Girl, Straw Cat, Dolly, Mika, Fimini, Charlotte, Lynette, Aloy, Thomma, Carveh, Layla, Candace, Lisa, Heizou, sometimes after a long time, even their names will be forgotten.
Of course, when you have enough resources, you will be promoted to whoever you love.
