Field Icons pop up a lot, so stay alert. Also, there are some areas where you might not be able to see where you are. Whenever that happens, pop out the HERE Icon. Press [SELECT] to call the HERE Icon. You can pop out the HERE Icon anytime by pressing [SELECT]. Also, you can turn on/off the icon in the Config Menu.

In addition to these, there are status effects known as Doom and Gradual Petrify. Remember this! If all your party members incur KO, Stop, Petrify, or Venom during battle, it's Game Over! Also, you won't receive EXP or AP if you're still under KO, Petrify, Virus, or Zombie when the battle ends.
