Guide updated
Plan the next valid rift checks from run time, consecutive misses and current blockers. The output explains probability growth and the chance of success across eligible checks.
Check the 28-minute cutoff first
New rifts stop at 28:00. At 30:00, Arceus takes the run into the Ruins of Judgment. Arceus is invincible; dodge its warnings and contact instead of trying to kill it. A current rift arena can delay the transition until you return.
What to do
- Enter time and valid misses.
- Mark a live boss, existing entrance or arena.
- Read what blocks the next check and the future valid-check distribution.
Numbers & conditions
Checks after >75 seconds use a 30-second countdown. Chance is 0.2×(1+misses), reaching certainty at four previous valid misses. Entrance lifetime is 45 seconds and arena time is 120 seconds.
Common mistakes
Placement can fail after a successful roll. A timetable estimate cannot observe the game’s internal countdown, so treat valid-check counts as the precise model.
