During chapter 4 in Octapath Traveler, near the end of Ophilia’s story, you will encounter Mattias. He has several defensive shields to protect against damage, but once you take down the shields, he becomes vulnerable to his weaknesses.
The second phase strengthens his defenses with cultists and black matter, making the fight even more difficult. This guide helps you defeat Mattias with the right strategy.
Mattias location
Mattias is at the end of Ophilia’s Chapter 4 in Octopath Traveler. To find him, travel to a place in the Flatlands called Ebony Grotto on the Continent of Osterra.
How to defeat Mattias in Octopath Traveler?
Mattias’s only defense is the four shields that reproduce twice; therefore, he targets his elemental weaknesses to deal maximum damage. This will weaken him during the first phase of the fight.
When the next phase begins, Mattias will summon 2 Senior Cultists. This will make the boss ineffective against magic attacks. So, to give him damage, take down these Cultists first.
After taking down the Cultist, Mattias summons Black Matter, and this time, you will be able to deal with magical damage, but he will not be vulnerable to any of his weaknesses now.
Weaknesses
Mattias is weak against Ice and light; therefore, you should choose attacks related to that to deal maximum damage. Meanwhile, you can select weapons like Swords and Axes to deal further damage.
