Starfall in Sol’s RNG is a temporary weather event, and the usual duration reported by guides is about 10 minutes. The Universe Potion is described as a personal Starfall effect that also lasts 10 minutes , which lines up with that timing.

Quick Scoop

  • Starfall duration: about 10 minutes.
  • Why it matters: it affects aura rolling and special Starfall-related rewards.
  • Related effect: Universe Potion gives you your own Starfall for 10 minutes.

Note

Some guides focus more on what Starfall does than on exact timing, but the clearest published reference I found gives the duration as 10 minutes. If you want, I can also give a short list of what Starfall changes in-game.
