I beat the naga xydussa but afterwards i cant get the door to open to progress through the maze. I looked for a key switch and i looked along the wall. I went to the other area with the two treasure chests and the fountain
what am i missing

You can always cast spirit eyes to see if you missed any hidden features on the map. Hope that helps! I’m almost at that point on my current play through actually.

yea ive looked for switches along the walls. i know there is a switch in that gong looking thing but it controls another door opening and closing. ive yet to get through that door and it takes you to the rest of the maze to the elevator puzzles

i got it

Yep, there is a switch on the circular monument in the middle of the room where you kill Xydussa.

switch I had trouble with was hiding above the fountian took couple tryies to find it
