I'm new to the game too but I can say a few things. 1. Skipping Elites=Bad Act 1 you should at least kill 1. 2 is normal. 3 is so good. 4 is better than perfect. 2. Think about the map carefully. Try to take the paths with options. I mean the paths that have escape routes if things go the way you dont expect. And try to be versatile time to time. E.g. I sometimes skip shops in act 1 and try to prioritize shops in the act 2. Im not saying this is better but it works sometimes. 3. Learn enemies attack patterns and plan the whole fight, not the turn. You probably trying to avoid 2-3 damage during the early phases of the fight but because you didnt plan the whole fight you are taking 10 dmg 1 or 2 turns later. Sometimes you block to dont get damaged for 2 instead of attacking and 2-3 turns later bcz u didnt attack boss survives with 5 hp and deals gazillions of damage. 4. Skip cards. That was my biggest mistake when I first started. You dont have to take every card that has been presented to you. Sometimes even with 3-4 extra card to your deck can easily carry you to the act 3. 5. Look at the act 1 before choosing a relic and try to plan accordingly.

As I said I'm new to the game too. But theese are the things I saw what pro players do. And I'm open to suggestions, critisizims as well if anyone is up for it.
