I WAS ABLE TO ACTIVATE AND BEAT BOTH. Mine was bugged for a while and I ran all over the map.

I saw a lot of people post that they killed all the monsters. I did as well, until just two left (I assume the bosses)

But what was different and I don't believe mentioned was that I opened all the doors that lead to outside. Perhaps the door trigger isn't working correctly, but opening them all helps.

Good luck.


This seems to work. Opening random doors fixed the issue for me.
Map with Delirium, fight not starting

Help to me: back to Hideout and go to Arena again.

Just ran into this issue.

Used low-level Unearth spell (lvl13, but I do not think it matters) and cast on on Avelyne, the crazy singing dancer. Worked first cast.

Method came from: https://www.reddit.com/r/PathOfExile2/comments/1n9tba3/bug_can_not_activate_boss_fight_in_derelict/
i just had the same problem 1min ago ... an unearth cast was a perfect solution so thanks ;)
Still bugged
This is out of control. Months have gone by and still not fixed. Pretty special

Wow I can't believe this worked. I just did this today (October 31, 2025) because I had encountered this bug (again), despite them saying it was fixed in previous patches.

I opened every door to the outside and killed every monster, and the boss fight still wouldn't start. So I did the Unearth trick, and the boss fight immediately triggered. LOL.

Thank you for this tip!
