So let's be honest, your first week of gameplay is filled with frustration and not much fun. It's a bit overwhelming.
One of the things that I learned quickly was that I was wasting my time. I was literally losing every match and hope for sheer luck or surrender to get through my daily quest.
It works, but you get your one chest and then repeat the next day hoping you picked up a little strategy during the slaughter. So to make it more fun I bought the 10 quest potion pack and regardless of price it does make it more fun. Just opening multiple chests is about as much joy as I can expect after my first week and when I run out i will buy gain.
So here is what I got today. Nothing great but the Sand Worm might make an appearance for me in battle. You never know.
