Story Bosses Always Have Weaknesses that the Corresponding Hero Can Exploit
Every chapter in Octopath Traveler features a dungeon and a boss fight, and when you encounter the boss itself, they’ll definitely have a weakness that the story character can exploit. For instance, if you continue Alfyn’s second chapter, the boss will be vulnerable to either ice or axe attacks, as those are the basic damage types Alfyn starts out with as an Apothecary. This means that you should try to bring characters with overlapping weapon and magic types as well, so you can break the enemy’s shield more effectively.
However, as a general rule of thumb, you’ll also want to make sure you have all the weapon types covered at all times. As you progress into the higher level content, bosses will start changing their weaknesses, and you need to be prepared for whatever they throw at you. Because of this, mixing the Hunter and Warrior classes is a great idea as you’ll gain access to the sword, axe, bow, and spear types.
