Generally, you should include:
When you fight the 1st worm boss (i’m level 10) and it brings you in the ancient area through worm hole. I took it, then I was confuse. I though I needed to took it again to cross to the checkpoint (like in Diablo 3 act 5) but instead it brings me back to the other era. My mistake, no worry, just a little confusing.
The problem is that the wormhole was now close so I couldn’t get back to the ancient era.
Suggestion: leave the wormhole open for mistake like that. And maybe an animation showing me that I get out of it would have made it clear for me that it wasn’t the way forward.
Thanks!
