How do the random Bane Bringer raids work during the Bewitched event?

Question

During the Bewitched event it is possible for Bane Bringer raids to spawn "randomly" throughout the day besides the guaranteed spawns at the beginning of each phase. I was wondering if there was any more information about these random raids.

For example, do they have a chance to occur every 15, 30, or 60 mins after the servers come up? Or, are they truly random and can occur at any point, even several times within the same hour?

Answer 1

From my experience, I know they have a chance to occur every 25 minutes.

You just need to catch the exact time when one of these random raids occurs.

Do we know when the first one happens after the first ss? is it 25 minutes AFTER the cauldron is completely filled? is it 25m after ss? would be of great help if we update this answer

These raids have nothing to do with the cauldron. I believe there is no way to know when the first raid will occur. Unfortunately, I was unable to identify any pattern, other than the one already mentioned in my answer.

And it is worth mentioning that the possible times for a raid to occur change from one day to the next.
