Bosses

In Octopath Traveler every boss is a shield puzzle first and a damage race second. You do not lose because your party is underlevelled; you lose because you brought the wrong five weapon types and could not break anything. So the only question worth asking before you walk into a boss room is what kind of puzzle it is: does the weakness set stay put, does it rotate, does the shield count grow, are there adds you must clear first, or does the thing have a second body?

That is how this page is sorted. Five kinds of fight, five sections. The counting, since it is the thing everyone asks: our bestiary covers 35 story bosses across the four chapter tiers, split 8 in Chapter 1, 11 in Chapter 2 because Victors Hollow stacks four arena fights into one place, 8 in Chapter 3 and 8 in Chapter 4. On top of that sit the optional fights and Galdera, the true final boss, who is only reachable once all eight stories are finished.

One note because the search results for this game are a mess: this covers the 2018 original, not Octopath Traveler 2 and not Octopath Traveler 0.

The five kinds of boss fight

A fixed-weakness boss can be brute forced by one specialist party. A rotating boss punishes specialists and rewards coverage. A shield-growth boss gets harder every time you break it, which inverts the usual rhythm. An adds fight is decided by kill order before you touch the boss at all. And the two-body fight at the end needs two separate parties built in advance.

The table below is the index. Full bestiary rows with shield counts, weaknesses and drops for all 35 story bosses are on our all bosses page.

Fixed weaknesses: the fights one specialist party clears

Gaston, the first boss in Olberic's story, is the clearest example and our page says so outright: unlike Redeye he has no flexible weakness set, so one fixed spread of Spear, Dagger, Staff, Ice and Lightning used over and over is enough. The catch is elsewhere. He fights with two brigands and keeps summoning more on his turns, and the only way to stop the respawns is to kill them all in the same turn. Do that first, then break him with back-to-back spear strikes.

Gareth in Therion's Chapter 3 sits on the boundary. He starts at roughly 38,000 HP with 5 shields and does change weaknesses after every break, but Wind stays a weakness permanently, which turns a rotation puzzle into a fixed one if you have a Wind user. Kill his two thieves first, since they die quickly to Polearm or Daggers and are weak to lightning, then open on Staves and Wind and switch to Sword, Ice and Wind after his first break.

Manymaws at the end of the Derelict Mine is optional, has a low health pool, and dies to Sword, Axe and Fire. It is on this page only because of Foul Odour, which inflicts one of Sleep, Poison, Confusion, Silence or Blindness on the entire party for two to five turns. Bring Alfyn, who resists it and whose Boosting Balm cures it, and use Rehabilitate for eight turns of status resistance. Mattias in Ophilia's Chapter 4 is nominally an Ice and Light, Sword and Axe fight, but see the adds section below, because his second phase turns those weaknesses off.

Rotating weaknesses: bring coverage, not a specialist

This is the largest group and the one that punishes a party built around two weapon types. Miguel, the boss at the end of Alfyn's Chapter 2, rotates four times and the rotations are documented, so you can prepare for them exactly.

Look at that spread and the party picks itself. Cyrus covers Fire, Ice and Lightning, which appear in three of the four rotations. H'aanit breaks shields fast with Bow and Axe. Ophilia supplies Light for the early rotations and, more importantly, Aelfric's Auspices on H'aanit so her skills fire more than once. Alfyn is in the party by default. Miguel raises himself to five actions a turn twice, at 50% and again at 25% health, and breaking him strips it both times.

Redeye, the boss you must beat to move H'aanit's story on, runs four phases: Daggers, Bows, Staves, Fire and Light; then Daggers, Axes, Staves, Fire and Light; then Swords, Bows, Fire, Lightning and Light; then Spears, Axes, Lightning, Wind and Light. Light survives every phase, which is the shortcut. The real threat is status: Evil Eye petrifies, and Bestial Roar and Unearthly Roar both raise the chance of unconsciousness, so an Apothecary running Rehabilitate matters more than raw damage.

Simeon, the Puppet Master at the end of Primrose's Chapter 4, adds a second problem on top of rotation: he regenerates shields after you break them, going from 3 back up to 8. His phase 2 opener locks all his weaknesses except Dagger, and Master of Silence stops your party using skills entirely once he recovers from a break. Carry Herb of Clamor. Warbringer Winnehild is the cleanest version of the mechanic: Ice, Wind or Dark for the first three quarters of the fight, then Fire, Lightning or Light once she drops below 25% health.

Growing shields: the fights that get harder after you break them

Managarmr is the reason this category exists and it is the single best-documented fight in our coverage. The Great Direwolf has 268,239 HP and deals only physical damage, which means Crystal Armor or Dragonscale Armor and no elemental resistance is needed at all. Our page puts the level floor at 65 and it is not being cautious: base hits land for 1,300, Savage Fang for 1,500 with Terror attached, and Savage Claw for 2,000 across the whole party.

The escalation is a fixed script, and knowing it is most of the fight.

He is weak to Axes, Lances, Lightning and Dark; the Direwolves he summons have 60,000 HP each and are weak to Swords, Staves and Daggers instead, so your break coverage has to span both. Equip the Double Tomahawk, which attacks twice a turn and strips defence quickly. Build one heavy attacker and use the other three as support: Olberic as a Warmaster with Winnehild's Battle Cry can land up to six attacks in a single turn across all enemies, which is what makes the twelve-shield stage survivable.

Shield inflation shows up in the story bosses too, though never this aggressively. Lucia in the Ruins of Eld sits at a flat 30 shields, Hrodvitnir climbs from 5 to 11, Yvon from 3 to 12, and the Venomtooth Tiger from 6 to 10. Those numbers are all in the bestiary.

Adds and kill order: fights decided before you touch the boss

Mikk and Makk in Tressa's Chapter 1 are the tutorial version. They cover for each other, and when one covers the other the weakness switches to whoever is standing in front, so a targeted attack is simply wasted. Mikk is weak to Spears and Axes, Makk to Bow and Staff, but both are weak to Wind, so Tradewinds always connects regardless of who is in front. Kill Mikk first because his health pool is lower, then expect the survivor to buff his own attack and defence for five turns and turtle through it.

Orlick in Therion's Chapter 2 is three fights in one, and the weakness sets do not overlap. Orlick himself takes Polearm, Dagger and Axe plus Wind and Light. His two bodyguards take Sword and Staff plus Ice and Dark, and they have only 1 shield point which they raise to 2. Midway through he activates a golem with 8 shield points that is weak to Dagger and Bow plus Fire and Wind. Kill the bodyguards first, because Orlick's weaknesses do not unlock until they are dead, then handle the golem. The damage figures are worth respecting: Magic Grenade lands for 890 across the party and Rage for 700, rising to 1,000 if the golem chimes in with Lightning Bolt.

Rufus in Primrose's Chapter 2 follows the same shape more simply. He takes Spear and Staff plus Light and Lightning; his two Obsidian Associates take Axe and Dagger plus Ice or Wind, and he can call two more mid-fight. Clear them with a hit-all ice spell, then hit Rufus with multi-spear attacks or lightning and light magic. Left-Hand Man lands 500 on everyone and can knock members unconscious for two turns, so party healing has to keep pace.

Mattias belongs here too, despite looking like a straightforward Ice and Light fight. In his second phase he summons two Senior Cultists that make him effectively immune to magic, so those have to die first. Then he summons Black Matter, at which point magic works again but he is no longer vulnerable to any of his weaknesses at all. Reflective Veil handles his magic damage while you wait it out.

The two-body endgame: Galdera and the Omniscient Eye

Galdera, the Fallen is the true final boss and getting to him is a chain, not a dungeon. Finish all eight stories. Complete every one of Kit's quests, named on our page as Kit the Traveler, Search of Father I and Search of Father II, and all of Lyblac's. That makes the quest At Journey's End available, which sends you from the Impresario in the West S'warkii Trail to the Ruins of Hornburg. Find Kit and Lyblac near the Gate of Finis, and to get through it beat the eight shades of the chapter bosses, one per traveler. Our true ending guide covers the wider unlock.

Then the game asks you for two teams of four, and this is the part people get caught by, because the two phases want different things. Phase 1 is the Omniscient Eye, which is only vulnerable while the soul it has summoned is dead. The Screaming Soul takes Spear, Dagger and Bow; the Wailing Soul takes Sword, Dagger, Ice and Wind; the Eye itself takes Daggers, Axes, Staffs, Lightning and Light. Once the Eye's health drops past a point the souls gain an extra shield.

Phase 2 is Galdera himself, weak to Spears, Daggers, Bows, Ice and Light, with less HP but three underlings, the Abyssal Maw, Lyblac and the Blade of the Fallen, all of which must die before he takes damage at all. Once they are gone he takes three turns simultaneously, and he can nullify every buff you have in a single move, though he telegraphs it first.

What the fights collectively ask of your party

Read across our thirteen dedicated boss guides and a pattern falls out that no single page shows. Cyrus is named in the recommended party for the majority of them, because he covers every element except Dark, Light and Wind, and Ophilia is close behind for Light damage and Aelfric's Auspices. In practice that means two of your four slots are effectively spoken for and the real decision is the other two.

Three fights are decided by an item rather than a party. Simeon's Master of Silence needs a Herb of Clamor. Rufus's Pummel and Left-Hand Man both cause unconsciousness, so a Herb of Revival matters more than another damage skill. And Manymaws' Foul Odour and Redeye's roars both want Alfyn and Rehabilitate. Our items guide covers where to stock these, and our best party guide goes further on composition.

The optional fights and what beating them unlocks

Winnehild is the one to prioritise, because the Warmaster job she unlocks is what makes Managarmr survivable, and Olberic as a Warmaster is the main damage dealer in our recommended Managarmr party. The shrine locations are covered on our shrines guide and the job itself on our advanced jobs guide. The Derelict Mine has its own page in our dungeons guide.

Which drops are worth going back for

Most story bosses drop a consumable, usually a Healing Grape Bunch or an Olive of Life, which is worth knowing so you do not plan a detour for one. The ones that drop actual equipment are a much shorter list: Gideon's Dagger from Gideon, Omar's Axe from Omar, Gustav's Shield from Gustav, Lizardking's Axe from the Lizardman Chieftain, Miguel's Spear from Miguel, Gareth's Helm from Gareth, Mattias' Scepter from Mattias, Werner's Sword from Werner, the Rune Knife from Esmeralda, the Black Staff from the Mystery Man and Shady Figure, and from Simeon the Physical Belt, Mental Belt, Shadow Soulstone and Vendetta Coat. Off the optional list, Manymaws gives the Carnage Blade.

That is eleven equipment drops out of 35 story fights, which is the honest reason not to treat the bestiary as a shopping list. For what deserves an equipment slot once you have it, see our weapon and armor rankings.
