Spawn location is correct, however his spawn chance are very low.

P.S. Yes i aware of that there can be only 2 bosses at a time and you have to kill them in order to have a chance for some other boss to spawn.
However, it doesnt matter how many bosses you will kill, most likely that *** Sergant at second big room will spawn and Behemoth spawn chance are nearly 0.
It literaly took our group 3 hours of running in cycles killing all the bosses. We killed something like 20 sergants and 0 Behemoth spawns.

I am doing this dungeon right now and the lack of spawn rates for the Champions is extremely annoying. I am trying to get the Conquerer achievement and have only two Champions left to kill. Already did the group boss today and it is taking far, far too long. Also, never received the pet so had to put in the report for that.

Read the above post, there is no spawn times in Public Dungeons, there is just a chance that certain boss will spawn when you kill another boss and only 2 bossess at a time can be up (expect the time after server restart when all bossess spawn and only after their death "2 boss at a time" rule start to work).
