HoYoVerse has shared more details on Aetherium Wars, which will be one of the new events in the Honkai: Star Rail Version 1.4 update. It looks to be very similar to the Boulder Town Fight Club event that was featured in the Version 1.0 patch of the game. After the event period, Aetherium Wars will move to Conventional Memoir. This means Trailblazers can play through the Aetherium levels even after it ends.
Aetherium Wars will be available as soon as Version 1.4 of Honkai: Star Rail launches on October 11, 2023. It will run until November 13, 2023. In lore, Aetherium Wars is a trading card game (TCG) that transforms an organism’s data into “Aether Spirits” for players to train, upgrade, and fight with. To participate in Aetherium Wars, you’ll need to first complete the “Jarilo-VI — Future Market (II)” Trailblaze Continuance.
Event rewards include Stellar Jades, Credits, Tracks of Destiny, and Self-Modeling Resin. You will also be able to obtain either Serval, Pela, Hook, or Luka for free. The event will even have a Challenge Mode called “Hyperlink Match,” where you can challenge other playable characters.
Honkai: Star Rail is available on mobile devices and PC. The PS5 version of Honkai: Star Rail will come out on October 11, 2023, which is also when Version 1.4 and Aetherium Wars will launch.
