It just so happened that I wanted to give this a relaxed first shot. So the time could be cut by 1 hour or more probably if done properly and with some better RNG in some of the parts. I had a terrible Veteran Prophet, which ended up having a 2 way - 5 room layout which I chose the wrong direction first. Also DD4 Phase 1 lasted for like 6 minutes because the Ancestor is a big troll :)
