Day 5...

Entered Arena 9. Often get stuck in adventures, the main story, or events because I can't win in the later stages. Since I'm a free-to-play player, I open chests from ads, wait to open arena chests, and gradually strengthen my troops to clear stages. For the main story, I entered the 5th map, got wiped out, so now I'm clearing the 4th map by spending 500 gems to open the locked area, getting wiped out and then clearing it.
