or it has a spawn time? anyway I don't really like to wait 1 hour or so for it to spawn since it is not a boss and I need its blood for the quest, which it rarely drop. I had tried to hunt it on every channel and now I had to wait for it to spawn. Was originally going to post this in the game bug section, but then I realized it isn't consider a bug since it's not like it no longer spawn after kill, just have to wait a long time.
Well from what I experienced it took like 2 hour or so to spawn one or two of them after their death on their channel. If there were more people doing the quest, there won’t be enough for everyone and everybody had to wait. The blood is hard to drop as well, not to mentioned it also required in the next quest where one of the three stone was needed from it.
