In ORAS, do Crescent Isle or Cresselia's portal ever disappear?

Dec. 31, 2014

The very first Mirage Spot I found was Cresselia’s. I have been trying to soft reset for a perfect 5IV, but it is taking a while. I saved the game on Crescent Isle, but I am afraid that if I leave it to challenge Victory Road, I am uncertain of whether or not the Mirage Spot will remain.

If you save the game and power down while on a Mirage Spot, it will not disappear. However,as soon as you Soar/Fly to another location, the Mirage Spot will disappearand a new one will take it’s place.

One final note: There is only a 5% chance of Crescent Isle spawning on its own, a little higher with StreetPass. Congratulations on it being your first Mirage Spot. Kepp trying until you get that Cresselia (unfortunately, you can’t really check it’s IVs after a day is up)!
