The Treacherous Crossing inside the Endless Archive in ESO gives you a challenge where you have to cross the corridor before it resets. This is a lot easier to complete with two players, since one player can advance across while the other player operates the switches. If you are playing solo, you still have more time as compared to a duo but it will still be tricky.

Speed buff Major Expedition and/ or the Wild Hunt Mythic Ring helps with this activity.

  1. When you hover over the bar, you see the respective flower highlighted that is affected.
  2. Select the closest path first, and the furthest last. Because that is the order in which the flowers will reverse.

Sometimes if you are playing solo you might get bad luck and the positions are in a very disadvantageous way, you can still do it though but it will be tricky.
