Who are the hardest characters to get in GenshinImpact?
Collectively speaking, the 5-star characters are the hardest to get. You have a 0.6% chance of getting one normally, but you’re guaranteed to get one after 90 pulls.
As of now, the below 5-star characters are always available to be wished for on all the banners except Epitome Invocation (weapons banner):
However, there are some other 5-star characters who are only available during their event wish (which usually lasts a couple weeks) and cannot be obtained after that on any banner unless there is a re-run for that character.
As of now, these characters are Venti, Klee, Tartaglia, Hu Tao, Ganyu, Albedo, Xiao, and Zhongli. However, more will be added to the game as it progresses. The chance of getting these characters when they don’t have a promotional event/banner is 0%.
