Act 4 Edge of Reality - Can I go back?

Question: With the quest to open the way to the Clone of John Bourbon, does that make a permanent portal or can you only get there once?

I am pretty sure I did it on my main character a while ago, but when I go back there is no spirit or portal or anything. Is it a one shot thing or is something not quite right?


The boss itself is a one time kill.

No it isn’t you can kill it as many times as you want.

Thanks for the responses.
I wonder why its not working.
I have tried to find Daila Thornsbury again, but she is not at any of her listed spots. She has buggered off.

You’re right, I must’ve mixed it up with Mogdrogen, my bad.
