Genshin Impact

This is the final battle in Genshin Impact but your friend that is a hydro claymore is dying and if they die they won't become a playable character. You are Aether in this talkie (I'll make on for Lumine fans if they blow up the comments). This friend is named Ackeron and everyone else is busy fighting the Fatui so it's up to you to get Ackeron to safety and make sure he lives.(WE NEED A HYDRO CLAYMORE)
