The spawn time of the undead cavebear starts to count when it firts appeared or when it was killed?

Question

I have been looking for the undead cavebear for my secondary character. I heard rumours that it appears 3-5 hours after the last one. But my doubt is, this clock starts when the first cavebear was killed or when it appeared? After i killed the first, I came back with the maxila maximus and waited there, from 3h after I killed to 5 hours. But it didnt appeared

Answer 1

Time starts counting from the moment the first undead cavebear spawns, not from the time it is killed.

3 raids in total, and the interval between them is 5 hours.
