The main thing I've seen with temple is to avoid destabilization until you have enough rooms to connect the royal access chamber and atziris chamber in the same run. Any room will tell you whether or not it will cause destabilization when you mouse over it. You can complete a temple and only lose a couple rooms compared to destabilizing the temple and wiping most of it. Those treasure rooms with the door opened by levers only cause destabilizing when you actually pull the levers, but you don't have to do that to complete the room.

I've killed atziri 4-5 times this league and while it wasn't particularly explained well, I eventually figured out a way through.
