Common Mistakes
Don't push Risk too high in your very first season — a higher score isn't worth it if your team collapses and burns through all your attempts. Don't ignore Test Criteria when choosing one, since each criteria changes the rules and can either counter or boost the team you're running. Don't forget to redeem Secret Sanctuary rewards before the season ends — many seasonal rewards don't carry over.
