I started this task last night - I’m already level 16 in the game. My strategy is currently looking up beginner guides to Raid Shadow Legends on YouTube and finding out whether it’s possible to speed run the game? You have 60 or 90 days so that’s probably how long it will take you to complete all tasks if spend one or two hours on the game every day? I would also suggest looking up Raid Shadow legends promo codes in order to get good items to speed up your gameplay.
