Fortnite’s Holofoil power hour is scheduled to raise the appearance rate of Holofoil Sprites during the event window. Multiple outlets report that the event features increased spawn rates specifically for the new Holofoil Sprite variants. One source also notes the start timing and provides a regional breakdown for when the power hour begins.
According to Polygon, the Holofoil power hour is set for Saturday, June 12, with start times varying by region. Vice similarly points to a specific go-live date and indicates that players can find the event schedule and start times for every region. It also states that the event includes rewards and lists the different Sprites available during the power hour.
While the two sources mention different calendar dates for when the event runs, they consistently describe the same core gameplay change: during the Holofoil power hour, Holofoil Sprites appear more often than usual, with the event tied to a limited-time schedule and region-specific start hours.
