Cosmicon, Roll On Event Guide for Honkai: Star Rail

This event will run starting in Version 4.0, which begins on February 12th, 2026. After the end of patch 4.0, the event will be added to the Conventional Memoir.

Players who complete the event during the duration of Version 4.0 will be able to earn extra limited-time rewards as well as all permanent rewards from the event. These limited time rewards will not be obtainable anymore after the event is added to the Conventional Memoir, but the event will still grant the same permanent rewards.

Cosmicon, Roll On! is a combat event based on popular tabletop games. You will have to face NPC trainers and other players in a duel to obtain valuable rewards, such as Self-Modeling Resin, Tracks of Destiny, Stellar Jades, and a unique Trailblazer Fashion Item!

In order to participate in the Cosmicon, Roll On! event, you need to reach Trailblaze Level 21 and complete Trailblaze Continuance: The Blue — When the Stars of Ingenuity Shine in the Herta Space Station.
