Mihoyo has recently confirmed that Kamisato Ayaka will be coming to Genshin Impact soon. The developers have yet to mention who else will be included in her Character Banner. However, leaks have pinned down the other three 4-star characters who'll join her in the pulls.
Genshin Impact Ayaka Banner Leaks
According to leaker abc64real, the upcoming Kamisato Ayaka banner is said to have Ningguang, Chongyun, and Yanfei. So far, Ningguang and Yanfei are 4-star characters that have potential to be a strong supportive DPS character in her team. Meanwhile, Chongyun allows Ayaka to keep enchanting her sword with Cryo damage which is her main gimmick.
Mihoyo has yet to confirm if these three characters will accompany her in the banner.
Chongyun, Ningguang, and Yanfei
If not aiming to get Kamisato Ayaka, getting these three characters is also a good investment for your rolls. All of these three characters actually have the potential to be one of the better characters with enough constellations.
As of now, Ningguang is one of the few characters that greatly benefit if her constellations are unlocked. Getting multiple copies of her during the Ayaka banner can further boost up her abilities and be a strong supportive DPS for the mean.
Meanwhile, Chongyun is one of the prime support characters where applies Cryo damage to areas and even enchants melee weapons with Cryo too. Due to his abilities, he's a mainstay pick in top team compositions.
Lastly, Yanfei is known to be one of the Pyro Catalysts that has a potential to deal strong damage alone. With the right equipment, she can blast foes with stronger Charged Attacks that drop foes fast.
Genshin Impact Ayaka Banner Release
As of now, Ayaka is slated to be the first banner to be released in Patch 2.0 according to leaks from the beta. After her banner, the next banner will have the two of the new characters, Yoimiya and Sayu.
After both of these two, the Patch 2.0 concludes and players are still in the dark in for the next batch of character banners.
