MiHoYo has unveiled new information for the Fate/stay night [Unlimited Blade Works] collaboration event coming to Honkai: Star Rail. The collaboration event starts on July 11 at 12:00 (server time). It will feature a story supervised by Fate/stay night writer, Kinoko Nasu, and have two special collaboration characters.
The first of these characters is Shirou Emiya’s Servant and heroine of the visual novel’s Fate route, Saber. She is a Wind type character and follows the Path of Destruction. Saber has a brand new design not seen in her past appearances. She will be available to summon via the collaboration warp.
The second character is Archer, the mysterious red-garbed Servant of Rin Tohsaka. He is a Quantum type character and follows the Path of The Hunt. Archer, like Saber, will have a brand new design for this collaboration event. He is available to claim for free from the start of the collaboration to the end of Version 3.6. Archer is also available to summon via the collaboration warp like Saber.
It should be noted that the warp count for the collaboration warp is separate from other warps. So you cannot summon from other warps beforehand to build up pity for Saber or Archer.
You can check out a preview trailer for the collaboration which showcases Saber utilizing her Noble Phantasm below.
