Now it is easy to find the Citadels

Did you know that there can be 2 copper citadels at once?



You can see the pillars from far away



Sadly these bosses are so hard that i didnt even kill one of them

Yes, any combination of citadels can show up in close proximity to each other. It's RNG.

However, it's not always certain you can directly traverse from one to the other:



Regarding the fight, what I can suggest is using waystones that don't increase their damage or their health and refund the atlas boss difficulty nodes...

I use grey waystones for those fights. Finally i have over 4000 life+shield and survived 2 bosses.

A bug happened: i killed Doryani, picked up the fragment and got chased by lightnings. I lured them to Doryani and his "spaceship" crashed. I still had to run and run ... and gave up. The lightnings killed me and the map ended "failed"
