Roll near the caravan entrance to exit

If you roll near the caravan exit, you will be able to get out of the caravan in act 2 while it's still moving, allowing you to explore an area that (I think) you aren't supposed to explore.


Roll down


Now you are out of the caravan


You climb up the canyon wall


And you will see a shrine-like building with this inside.

Can confirm this works on any map with The Ardura Caravan. Even the ones with the teleport text. Although those are a little harder to pull off the roll on.

It doesn't seem harmful on the caravan, however.
As you still can't do anything back there. But maybe gotta check around gated areas that you can't just roll through the gate to skip something else.
