Octopath Traveler 2 Guide – How to Defeat King Mugen

King Mugen Octopath Traveler 2 This Octopath Traveler 2 guide will explain how to defeat King Mugen, the final boss of Hikari’s arc and the bloodthirsty demon responsible for Hikari’s father’s death.

Octopath Traveler 2 Guide – How to Defeat King Mugen

A Cleric is an essential component of your party build when fighting Mugen, as you’ll need to spam Heal More every other round. A party member who can equip axes and wields the Double-Tomahawk is also useful. The Double Tomahawk can be found in an ocean chest at the map’s bottom left. A Warrior is excellent for the second stage of the battle, because of Aggressive Slash.

I mention the Tomahawk and Aggressive Slash for one reason: you’ll be using your BP a lot. This weapon and move will bypass the BP restraint and whittle Mugen down, making the fight much easier in the future.

Mugen’s Stats and Weaknesses in Octopath Traveler 2

  • Shields: 7 – 9
  • HP: 80,000
  • Weaknesses: Polearm, Axe, Lightning, Holy
  • Weaknesses 2: Sword, Ice, Wind
  • Attacks
    • The Conqueror’s Rule – Hits all party members and inflicts a debuff that prevents them from using BP for one round.
    • The Conquerer’s Tyranny – A single-hit physical attack on one party member that does around 1,000 damage.
    • Mugen stands ready… – This is a charge attack that leads to decapitation, a move that will leave one party member with one HP.
    • The Conqueror’s Might – A physical party-hit attack that does 800+ damage.
    • Mugen’s Soul Rages – Charge attack, signaling Mugen’s transformation.
    • Gates of Hell – Physical attack that hits two party members, leaving them with 1 HP.
    • Conqueror’s Blade – Physical attack that hits one party member for over 1,000 HP.

Mugen will start the fight with two attacks: The Conqueror’s Tyranny, which affects only one member of the party, and The Conqueror’s Rule. This is a preview of how Mugen will play. He’s a heavy hitter who usually attacks twice in a row, once with a debuff and then with a party-hit physical damage attack.

When Mugen is defeated for the first time, he will use his charge move, Mugen Stands Ready. And while you would usually have the chance to defeat a boss before he uses it, Mugen will immediately reduce one party unit to 1 HP because he always attacks twice.

There are no other real gambits in the first half of the fight. All you have to do is keep your team healed and Mugen’s health low until a dialogue between him and Hikari occurs.

Mugen will then attack twice with the same combo he used at the start of the fight. But he’ll add one more move to the mix: Mugen’s Soul Rages. This is his charge attack.

Mugen will change his weaknesses and shields, and he will start using attacks that are much stronger. Gates of Hell will hit two members in the party, bringing their HP down to 1. Mugen will now be able to use Decapitation without having to charge it first. This will let him bring another party member down to 1 HP.

At this point, at least one party member must be committed to keeping the party alive while you chip away at his shield. A warrior with Aggressive Slash becomes critical, as it is the quickest way to hack through Mugen’s shields and escape the onslaught.

However, if you haven’t defeat him in five more turns, Mugen will use Know your place again, signaling the beginning of a new shuffle of weaknesses and another hit from the Gates of Hell. You can’t save yourself by defending, so you might as well try to break his shields.

When you finally defeat Mugen, you will receive not only the satisfaction of victory, but also 9,900 leaves, 1890 EXP, and 675 JP.

This concludes our guide on how to defeat King Mugen in Octopath Traveler 2.
