StarSavior will be unavailable for three hours on October 1 while scheduled maintenance is carried out. The downtime runs from 1:00 to 4:00 UTC, with players unable to access the game throughout the entire window. This is a full interruption rather than a warning of reduced or unstable service, so anyone planning to play during those hours should schedule around it.
Compensation has also been specified in advance. Players will receive 100 Stellagems and three Standard Savior Observation Tickets for the maintenance. The practical takeaway is straightforward: StarSavior goes completely offline for the announced three-hour period, with a defined compensation package attached to the disruption.
