Version 4.5 of Honkai: Star Rail runs for five weeks and splits its featured warps into two phases, each headlined by a fresh five-star. Robin Summeretto and Hyacine lead the opening stretch, while Aventurine Waveflair arrives in the back half alongside an Ashveil rerun. The patch also stacks several limited-time events that hand out Stellar Jade, Tracks of Destiny, and a free four-star Light Cone.
