All the parts of the Unreconciled Stars event in Genshin Impact are now available, with the latest being the Star of Destiny chapter. This chapter continues the investigation into the mysterious meteorites with the help of Fischl and Mona, but also unlocks a new co-op event known as the Fallen Star Challenge. To see the event in action, check out the video above. Otherwise, read on below for tips about the event and why you should do it.
This challenge is absolutely worth completing at least seven times, as doing so (along with the other requirements of the Prinzessin's Pact that coincides with this event) will unlock Electro adventurer Fischl (or advance her constellation if you already have her unlocked). Unlike the Elemental Crucible event, you have to spend resin redeeming rewards to contribute to your Fischl unlock.
Even if that weren't the case though, you should probably redeem the rewards from this challenge to collect Fading Star's Essence, as they allow you to purchase items from the event shop. Most notably, you can buy a Crown of Sagehood, which allows you to level a character talent up to level 10. As far as I know, this is the first time this item has ever appeared in Genshin Impact, so make sure you grab it.
As for the challenge itself, it's otherwise not too unlike the Elemental Crucible. You join with a co-op team (or can be boring and play it solo) and kill enemies to fill a meter. Once your meter is full, you can run under a glowing area in the event zone to activate a submission animation that lasts five seconds. Your goal is to submit enough energy to fill an overall meter, but all the while tough enemies are spawning into the map.
In terms of strategy, I recommend bringing any solid support characters into the co-op challenge, as I've seen mostly strong damage-dealing characters join the event who could use some backup in terms of healing, buffing, etc. Cryo adventurers are also a good pick because their freeze abilities can make it easier to submit energy without worrying about being attacked.
