Questions about Torghast

Hey guys thanks for reading.

I had some questions about Torghast that I can’t find answers for online.

  1. Is there a way to see if a Torghast layer has reset or will not give you rewards?

  2. Can you run each layer of Torghast once per week? If this is the case can you just run layers 1-8 and get the sum of all the possible soul ash of each layer once a week?
