World Bosses, How do they work?

OK… so Ive read and heard that WB are suppose to spawn every 4hrs. But it happened to me several times that I was able to kill the boss, so I was able to time it but when I come back after 4hrs… nothing! So… how does this really work?

Most WBs spawn in one of several locations (ex: Harpeia spawning in Demon Prison D1, 2, and 5) and are most likely spawned in a random channel on that map.

The timer might have some variation in it, but I’m not 100% on that one, search around a bit, the info’s probably out there already.

funny you should mention Harpeia, hehe. thats the exact boss that I had a timer on. killed it on ch5 and D2. then I informed my friends and I had them go to D1 and D5 while I scanned D2. It simply didnt spawn. lol
