Here are all the bosses in Valor Mortis.

Spoiler warning: This guide names every boss in Valor Mortis, describes their appearances, and covers key fight mechanics, including late-game encounters. If you have not yet reached a boss listed below, stop reading at that point. Several of these fights are best experienced blind.

Valor Mortis offers no summons and no support of any kind, so every boss must be solved alone. What follows is a full rundown of the game's boss roster in the order you meet them, with the location of each fight and practical tips for coming out alive.

Background: a first-person Soulslike with no co-op safety net

Valor Mortis is developed by One More Level and puts you in the shoes of William. Its combat is fast-paced and first-person, built around parries, stagger bars, critical attacks, and a Transmutation system that lets you apply elemental effects such as Fire, Stasis, and Shield. Because there are no summons, preparation and loadout choices carry more weight than they would in a Soulslike with cooperative options.

Bosses are where that design shows most clearly. Many of them punish passive play, several have multiple phases or multiple health bars, and a few are explicitly built around gimmicks rather than pure dueling. The roster leans heavily on mutated abominations, which will feel familiar to anyone who has spent time with Dark Souls 3.

The boss roster at a glance

Early game: the first two tests

General Lothaire, The Eagle Bearer is the first boss you face, and by tradition he is fought twice. The first encounter in the Valley of Ashes is scripted to end with your death. The rematch, before you enter the Abandoned Church, is where you get to beat him properly.

His moveset covers a sweeping combo with his mutated arm, lunge attacks, and projectiles fired from guns mounted on his back. Most of it can be parried, which builds his stagger bar quickly and opens the door to a critical attack. He works as a tutorial in miniature for the game's fast-paced first-person combat.

The Iron Marshall waits later in the Fallen Village. He is notably slow, and as a result less demanding than Lothaire. That is fortunate, because after this fight you will keep running into Remnants of the Iron Regiment, weaker versions of the same enemy, for the rest of the journey.

The key is distance. Fire Transmutation and ammunition let you burn him down while targeting the weak spot on his back. Melee is possible, but his sweeping attacks catch you off guard more often than is comfortable, so ranged play is the safer route.

Mid game: where the fights get strange

Sphinx, Devourer of the Unworthy is the turning point. After exploring the Caverns, you are magically whisked away to the Pyramids to fight Sphinx, and the encounter is described as reversing first impressions of the game entirely.

Stasis Transmutation and firearms do the heavy lifting here. Sphinx is extremely fast and agile, so Stasis is needed to slow them down and even freeze them in place long enough to land hits. They also have two health bars. The compensation is a weak spot on their face during the second phase, which you can target with the plentiful ammunition the fight drops.

Slaughtermill is arguably a gimmick fight, and one that recalls the Curse-Rotted Greatwood in Dark Souls 3. You target bulbous weak spots on the creature, and the second half takes place underground with a heavy platforming component and a soundtrack that feels strongly inspired by Mick Gordon.

Follow the prompts as they appear: shoot a weak spot, pull a blue Nepthoglobin node, or grapple over to the building itself. Between that and dodging tentacles and Carrion summons, the fight is less troublesome than what came before.

Anna, The Bride Drowned in Tears is a humanoid boss in the Cursed Hollow, compared to the Celebrant in Elden Ring's Windmill Village. She is fast and constantly slashing with a butcher knife, and she summons Shambling Civilians to help. She is also squishy and easy to stagger.

Fire Transmutation plus heavy attacks during her brief stuns is the core loop. Bring an explosive such as a Hand Grenade: the hardest part of the fight is the add summon, which can overwhelm you quickly, and a grenade solves that problem so you can return your attention to Anna.

Late game: duels, abominations, and the final confrontation

High Justicar Aurelius, Last of the Faithful is one of the game's Eternal Guardsmen, but something has taken hold of this soldier and allows him to mutate mid-duel. By this point you have fought plenty of swordsmen, and the fight plays as a melee duel: poke, parry when the opportunity appears, and let Fire add damage over time.

When Aurelius drinks from a flask, expect mutation: a huge bulbous arm, much like General Lothaire's, with long reach. During those windows, stay out of the way and dodge until the flask wears off. He is far easier to attack in humanoid form, where he poses less of a threat.

Experiment 33 appears after you enter the Lighthouse in pursuit of the mysterious Shrike from William's visions. It looks like something out of a Resident Evil game, a mutated abomination with more limbs than you can count, and it follows you around the Lighthouse basement trying to close the distance.

Fire is the answer. Circle the area while it follows, and turn to build Fire Transmutation whenever you have enough Nepthoglobin. This is also the moment to use Nepthtoglobin Vials. Build Fire, use firearms to hit weak spots from range, and the boss goes down quickly.

The Orphan takes things darker still. This figure, possibly already glimpsed lurking around the rotting laboratories, fights you in an arena with poison vents almost everywhere. You are dodging both the boss and the vents, and making use of the Shield Transmutation you have just acquired.

His moveset is not the problem; his damage and long sweeping combos are. Fire status keeps his health ticking down while you melee wherever possible. In the second phase, Oil Grenades are worthwhile when he is against a wall. Combined with Flaming Whetstones, Fire builds continuously and makes light work of the fight.

Captain Raphael of the Nephtis Superioris wields both a blade and a pistol, and after the fight William notes a striking but sickening similarity between the two of them. Raphael is an adept swordsman who can heal himself mid-fight, which forces aggressive play if you want a chance.

Where many bosses reward safe Fire-based play, Raphael demands the opposite. Nepthtoglobin Vials and the Shield Transmutation let you block his attacks, deflect his bullets, and occasionally stagger him. Staying close means you can attack him every time he reaches for a Flask, and a boss who cannot heal is far less intimidating. Grenades or firearms can also interrupt his healing in a pinch.

Entity, Voice of the Void opens as a fight against a humanoid enemy who looks terribly familiar, like looking in a mirror. There is more to it than that, chiefly the boss's summons: lots of them, and many you will not be happy to see return. Without spoiling the ultimate fight, be prepared to use everything you have learned across the whole game. The Shield Transmutation is essential, and the summons can each be taken out with a single hit. Prioritize clearing them before dealing with the boss himself.

What this means for your run

The roster escalates from a parry tutorial in the Valley of Ashes to a multi-summon finale, with the mid-game Pyramids fight as the clear difficulty and design pivot. Three tools recur across almost every encounter: Fire Transmutation for damage over time, Stasis for speed control, and Shield for the aggressive humanoid duels. Nepthoglobin management and Nepthtoglobin Vials matter most in the Lighthouse basement and against Captain Raphael. Since Valor Mortis offers no summons, the only way past any of these bosses is your own loadout and execution.
