F.O.E.s are not just obstacles; they can be exploited. Many F.O.E.s have predictable patrol patterns that can be used to your advantage. Some can be lured into traps, others can be distracted with items like 'Chakra Pots', and some can even be used to break down walls or activate switches. Observe their movement carefully on your map. If an F.O.E. is blocking a path, look for alternative routes or environmental elements that can help you bypass it. Sometimes, leading an F.O.E. into another F.O.E. can trigger a battle between them, allowing you to sneak past. Don't be afraid to experiment with their behavior; understanding their AI is key to navigating the more complex labyrinths. Remember that defeating F.O.E.s often yields rare crafting materials.
