Mysterious bosses from Otherworld

There are two not-so-well researched bosses in the Otherworld – Burster and Dreadful Disruptor. It has been a few years since implementing them to the game, but they are still shrouded in mystery. With this article, we would like to dispel the doubts about their spawning mechanisms once and for all. You will be able to meet them relatively quick, thanks to the knowledge contained in this text.

What do we know about these bosses?

Both Dreadful Disruptor and Burster are not researched well due to the fact that the number of kills is very low. At the time I wrote this article, Burster was killed 838 times and Dreadful Disruptor 515 times. It’s not much if we consider the fact that we talk about all servers in game. It leaves some room for speculation. We don’t know exactly what do they drop. The first Wand of Dimensions dropped from Mazzinor probably after several hundreds of kills and Yeti drops Bunnyslippers probably with 1/1000 chance. It really stirs the imagination.

Other than that, up to this point, we know how these bosses look like and where, more or less, they respawn. I’m not going to repeat the known facts. You will find them here:


Dreadful Disruptor

It’s worth mentioning that bosses are stronger than other monsters around. Especially Dreadful Disruptor requires special attention, as it deals massive amounts of damage. During a fight, I noticed that it’s much stronger than Zushuka or Tyrn.

Where can I find them?

Burster respawns in a place known as Otherworld (Dwarf_Bridge) in the area marked with yellow in the screenshot below.

Respawn of Dreadful Disruptor can be found in Otherworld (Edron). I marked his respawn area in the picture below.

How do they respawn?

Until now, the bosshunters community had some theories about this matter. One of them stated that these are randomly respawning bosses. The other one – that you have to kill the specific number of monsters in the Otherworld dungeon to make them appear. The last one was based on a suspicion that the respawn is exchangeable, similar to Mahatheb for example.

Due to the fact that the bosses spawn time is extended twice, I started to check every possible spawn spot of the monster in this area. I figured out that one spawning spot is extended in time. It is exactly the place marked on the picture below.

It’s easy to recognize the exact spot, as the respawn is slowed down. Burster appears once in a while instead of Instable Breach Brood. To meet the boss, you have to stay in this exact place and kill respawning Instable Breach Broods. After some time, Burster should appear. I broadly described this mechanic in the 2nd article about Mahatheb.  Unfortunately, we didn’t manage to determine the approximate number of Broods needed to kill, to make the Burster respawn. Triggering the Burster and Dreadful Disruptor respawns took me about 3-4 hours. On the other hand, Bosst from our team spent over 25 hours trying to respawn both bosses with no result.

Dreadful Disruptor spawning mechanic is exactly the same as Bursters. Once again, you have to stay in a specific place and kill Stabilizing Reality Reavers. There is a chance for the boss to respawn instead of them. I didn’t find the exact spot, but the respawn of Dreadful Disruptor is in the middle of the marked area (2 screenshots above).

Both Dreadful Disruptor and Burster can appear more than once per day. Just check this screenshot of Dreadful Disruptor kill statistics taken from

This also provides hard proof of the shared spawn theory. Because this type of respawn allows you to meet more than one boss a day.

Useful notes:

  • It’s quite hard to meet these bosses. Usually, many hours of tries are needed for the first to spawn.
  • I have never met a boss twice in one day. This must happen extremely rarely.
  • During the fight against the Burster or Dreadful Disruptor you can go downstairs. There are no monsters in the underground area, so you can easily refill the mana and HP there.

Happy hunting Bosshunters!

A friend and I killed this boss twice today, february-09-2020. We were actually charming in different times of the day, and we both found it. I think that mechanism regarding a certain amount of kills to make the boss spawn might be accurate, but I didn't step in a exact SQM to wait for it. To be honest I only realized it was a boss when I took a hit that dropped my health from full to deep yellow (i'm ED 370+ In Vunira). Didn't drop anything special, only regular brood products.

Sorry, forgot to mention which boss: the Burster.

You were very lucky. I spent over 30h staying in the exact spot where the boss respawns, but I didn't get it to spawn.

I'm not sure you'll be able to see it, but this is a friend's SS with the boss. I killed it also that day, 3-4h latter. We were finishing charms at that spot.

Congratulations. Did you manage to observe the spawn of the boss?
March 10, 2021
Sadly, I couldn't check the precise spot it spawned... But my EK friend (on the screenshot) told me it was some few SQM to south-west of the box he is on the picture - probably spawned in the previous 8box (you can see the dead monsters south-west of him). We're gonna try to find the Edron one these days, wish us luck! :)

Of course, I wish you the best of luck. If you kill this boss, please send a screenshot. It's always nice to see another rare boss kill.
September 11, 2021 and Was chamring there today and manage to kill Burster twice, both of them spawned so randomly.

I found Burster in antica one time by accident, while making the Cube quest again. I didnt have to kill monsters to force a spawn, but theres no way to know if someone was hunting there and they gave up 1 kill too early and left the boss behind for me. Just wanted to share. Great article, all the info that I was searching for now.
