Reaching C6 in Genshin Impact unlocks a character’s full potential via Constellations. Some characters become game-changers at C6, while others offer more modest improvements. This tier list ranks all C6 characters in Genshin Impact, so you can decide which characters are truly worth the investment of your pulls and Primogems.
They FORGOT he was a 4 star… (C0 vs C6 COMPLETE Gaming Review & Guide)
In Genshin Impact, "C6" refers to a character's sixth Constellation, which is unlocked after you draw that character through the Wish system six times. The "C" stands for Constellation, which is a set of upgrades specific to each character. Each character starts at C0, meaning they have no unlocked Constellations. To reach C6, you'll need to draw six additional copies of that character.
It’s important to note that 4-star characters are much easier to get to C6 compared to 5-star characters, as 4-star characters are more common in Genshin’s gacha system. Certain Constellations can significantly enhance a character’s abilities, making them much more powerful or versatile in gameplay. However, there are also times when a certain character keeps showing up in your rolls, and it can feel like you’re stuck getting copies of someone you don’t want.
Reaching C6 essentially means you've spent a lot of time, resources, or luck to pull that character multiple times. Below you'll find my tier lists of all Genshin Impact characters, taking into account their C6 tier. I've broken these down into DPS, Sub-DPS, and Support characters. Keep in mind that many Genshin Impact characters cross these categories.
