Martyr Logarius (殉教者ローゲリウス Junkyōsha Rōgeriusu lit. "Martyr Logarius") is a Boss in Bloodborne.

Martyr Logarius Information

  • This boss fight is optional. Make sure you have lit the Cainhurst Castle lamp before defeating this boss or you will respawn near the horses that brought you to Cainhurst.






Combat Information

  • Strong against Fire, Arcane and Bolt damage.
  • Spells deal Arcane Damage.
  • Logarius can be staggered with firearms quite easily during his second phase when doing physical attacks. Bring Quicksilver Bullets and take advantage of these staggers with Visceral Attacks. 
  • He can't fall off because of invisible walls over there on that roof. The player, however, can fall off of the roof if care is not taken.
  • Use the obstacles on the rooftop to break off the line-of-sight of his spell missiles. When he stabs the roof with his sword, swords will spawn in the air and shoot at the player, to get rid of them simply attack the sword (you can lock on to the sword to shoot it).
  • Caution: when he buffs himself he gains an aura that causes bullets to pounce off him and melee attacks to no longer interrupt him. however, staggering him with a bullet or a backstab causes him to lose the aura. Note that each time logarius stabs the roof with his sword he gains an extra stack of the aura which means it might require more than one stagger to break the aura.
  •  the player can backstabs him while he is charging his initial buff, causing him to stagger.
  • If you lock on and stand in-front of him while staying close to him as to lure out his melee attack you can get through the entire fight without him casting his buff. The sweet spot to interrupt his attack is at the very peak of the swing just before he brings the weapon back toward you. If the player can manage to keep him attacking and hit that sweet spot followed by Visceral Attacks the boss fight can be very easy.
  • When going for hit n' runs, only do 2-3 hits and then dodge left. He always summons his exploding skull off to the right side of him, so if the player dodges to their left, it should never connect.
  • It's possible to roll through the exploding skull Logarius summons when you are close up to him. This will let you stay on top of him when he backsteps.
  • Don't be tempted to use heavier weapons. Using the short version of Ludwig's Holy Blade or the sword part of the Kirkhammer will be more useful than the trick versions. If you can land a running combo on Logarius you can interrupt his attacks.
  • When Logarius starts to fly around, keep an eye on him in the air and dodge either towards him or just before he hits the ground. When he lands he is stunned for a second or so allowing you to get in and attack him again.



General strategy

Martyr Logarius is an incredibly powerful and aggressive boss. He attacks frequently and quickly and is capable of killing players within one combo. When you walk into the boss room Logarius will summon a ball of energy that tracks you slowly, so run to one of the sides of the roof and use the pillars to keep yourself safe from the blast. Sprint round behind him and start the fight proper.

Watch out for his frontal blast attacks early on. Whenever you manage to score a couple of hits on him he'll summon a red skull with an AOE blast which will knock you back and take off around 50% of your health. If you time it right when he puts his arm forward you can roll through the blast, or you can dodge to the left. The AOE is directional to the front. If you get too far away from Logarius he'll summon a ball of energy like he did at the start, or he'll cast a sweep of smaller skulls which track you. Roll through or just avoid them. If he swings his staff and you're close enough you can get in a gunshot and parry him, but the timing is very difficult.

When you take around a third of his health off he'll smash his staff into the ground and start charging up. When he does this, take the opportunity and do some real damage to him. Really hit him hard. If he doesn't have his back against a wall use this state to do a charge attack from behind and follow up with a visceral attack. While he's charging his defense drops so a visceral here will do huge amounts of damage to him.

Once he's finished charging the fight will change immeasurably. Where before he would avoid you and use magic, now he actively chases you and attacks directly with melee attacks (his fighting pattern is not too dissimilar from that of False King Allant in Demon's Souls). The prevailing tactic here is to bait his attacks, when he does a long stab with his sword you have a perfect opportunity to land a hit on him. When he stabs his sword into the ground get near it before the arcane attacks hit you and smash the sword, cancelling the attack.

When you get him down to his last third, the final stage will start. This time he'll continue the aggressive attacks but also periodically fly up in the air and smash down on you. When you see him fly up in the air, keep an eye on him and when he's close to hitting you, dodge. He'll hit the ground hard and be stunned for a second, so make sure to use the opportunity to get some hits in. He'll use his sword less in this phase, focusing more on two handing his staff for increased damage. Eventually though, if you're careful and DON'T GET GREEDY WITH HITS you'll best him.

When he's done, make sure to pick up the Crown of Illusions he drops. Wear it and you'll unlock the very end of the level.

Parrying strategy

During Logarius's second phase, where he concentrates mostly on using physical attacks, he is highly susceptible to being staggered and visceral attacks. Those who are having trouble avoiding his aggressively fast and powerful combos should have much better luck shooting him just as he launches an attack, staggering/parrying him, and then following up with a visceral attack. With the " Clawmark" Caryll Runes equipped, players can increase the damage of visceral attacks even more.

Co-op Strategy

If Logarius is proving to be too difficult, co-op makes this fight more manageable. To guarantee success you need to use the tactic described above, but make sure to get into a rhythm with your cooperator. Essentially the two of you should fall into taking turns to his Logarius as follows:

  • Player A attacks Logarius and pulls his attention. Player A may take damage, so should retreat
  • Then Player B attacks Logarius and pulls his attention while Player A heals.

Repeat that until you have the boss down. When he is charging up for his second phase, both of you should power in and get as much damage as possible on him while he is vulnerable. See the attached video below to see how this rhythm looks.

Attack Name Attack Description & Counter
Quick Frontal Blast Relatively quick and hard hitting attack performed in front of Logarius. To avoid try to dodge when he quickly juts his arm outward, or simply stay away from his front side.
Swirling Skull Tracer Logarius will raise his staff in the air and summon a circular swirling mass of skulls to follow his target with a small turning radius.This attack leaves him open while he is casting it. To avoid this attack, dodge to any side a few times.
Scythe Attack Combo Logarius will swing his staff 3 times, two being side swings and the last an overhead smash. He may stop at any point in this combo if you are out of range. To avoid this, attack him to interrupt it, or dodge away.
Lined Skulls Logarius will swing his staff and create a line of explosive skulls that trace his target. To avoid this, either use the castles environment to block the skulls or dodge around them.
Enrage At about 3/5 health Logarius will stick his staff in the ground with red haze surrounding him. After he completes his ritual he will gain a massive boost in speed, damage, and unlock a new set of moves. It is advised to attack him as much as possible as doing so will delay his ritual and continue to leave him open.
Sword Rain Only occurs after Logarius is Enraged. He punctures the ground with his sword which will cause a small scale explosion and cause swords to rain from the area above it. To avoid, dodge around and attack his sword to end it.
Sword Slash Combo Logarius will swing his sword twice rapidly at which the end of the combo will have the air he had sliced explode. He may end the combo early if his target is out of range. Avoiding this attack depends on where you are positioned in relation to Logarius. If you are close, dodge behind him, if not a backstep will avoid everything.
Leaping Attack Logarius will swiftly jump into the air and in a few seconds land on top of his target dealing massive damage. At the end of this attack he is open for a few seconds. It is recommended to dodge in one direction as much as possible. Unless you can time you dodge with his landing, it is advised to dodge spam.
Hovering Spin Logarius will backstep into the air and hover for a few seconds before swiftly flying across the map while spinning. This attack rarely hits his target and most often only hits another summoned player if you have Logarius positioned in such a way. If this attack manages to hit it will do massive damage. To avoid all mishaps, notice where your allies are and have Logarius face away from them. When he proceeds with this attack try to dodge to avoid the slim chance he actually hits you.



  • From the Executioners Set's description: "Acts of goodness are not always wise, and acts of evil are not always foolish, but regardless, we shall always strive to be good".



  • When asked about the Vilebloods, Alfred offers some insight on Logarius. According to him, Master Logarius led the Executioners in a charge against the Vilebloods at Castle Cainhurst. Alfred implies that Logarius stayed behind while the rest of the Executioners escaped. He hopes to go to Cainhurst, avenge Martyr Logarius and destroy the Vilebloods.
    • Alfred is able to accomplish this when the player gives him the Unopened Summons item found after the defeat of Logarius in the Vileblood Queen's chamber. After receiving the item, Alfred will go to Cainhurst and assassinate the Queen, after which he will return to his original location by the tomb leading to Old Yharnam where he takes his own life. The reason for his unexpected suicide is discussed under Alfred
    • Logarius is a vileblood and evidence of this is found with the ring found in chalices which was says that he intended to marry Analise thus proving that he is a vileblood 

Notes & Trivia

  • His sword is very similar in design to the Soulbrandt, a blade from Demon's Souls.
  • His scythe on the other hand is a replica of the one conjured by Pthumerian Elder.
  • Logarius is likely connected to the The Emperor Tarot Card.
  • The Sword of Logarius  much resembles The Drake Sword from DS1
    Like The Drake Sword it is very broad at the hilt and the edge is slightly curved, like a flamberge. The colors are different.
  • The sword that Logarius uses is a kris, an Indonesian sword with unusual curves.

      So I basically first tried this guy (he survived at like 1hp, no red left on his health bar) then went on to die about 10 times till i finally beat him. Amazing boss fight tho.

        I been saving this game for a Rainy day and it is was finally time. Def weren't joking about how long it is. Skipped the Castle after it took me something like 20+ melee attacks to kill a single worm/blood sucker when you enter the area for the first time (plowed through Nightmare Realm to kill Amygdala b4 returning). That gave me some good gems and stones to upgrade my weapons and give it another go. This guy must have been the hardest boss so far. Just learning how to dodge all his movesets and figuring out the stagger/parry frames took 4ish attempts alone. I been pretty basic with my weapon upgrades just sticking with the sawblade/pistol. I did however have a slightly lower lv Mercy Blades on me. 6-7th attempt I forgot to repair my sawblade so I had to swap out to my blades at about 45% hp and just murdered him =/. I feel if I had tried using them sooner I woulda got him on the second/3rd attempt.

          So far, this is the boss that gives me the hardest time... I can get through is first phase easily enough... His attacks are slow and I can avoid them without too much trouble... But after that, he's just too fast, by the time I dodge his attack and try to hit him, he already moved on to another attack. I do get some counter shot in, but my viceral doesn't make that much damage...

            The ring of betroval, referenced above, does not say that Logarius wanted to marry queen analise. Also, that sentence is so grammatically lacking that it gave me an aneurism trying to read. Seriously, if we are to respect this website at all, this needs to be removed. Who is the 12 year old moron who wrote that, anyway?

              I love fighting dis boss for two reasons. one he is one of the few boss that is not part of the dlc that feels like you have give 100 percent focus to beat him. Second you have learn his moveset to not get hit all the time. In short I like the boss :)

                Why is his first phase the hardest?! Killed me like ten times before I got him to second phase, once I got through it though, the rest was easy

                  "Whenever you manage to score a couple of hits on him he'll summon a red skull with an AOE blast which will knock you back and take off around 50% of your health." saying that when you don't know what hp the reader has LUL

                    I had a lot of trouble with this boss initially, but after taking a break and trying again the next day, I beat him after a couple of tries. Here are a couple of suggestions that seemed to work well for me:

                    1. Use a fast-hitting weapon (I used Ludwig's Holy Blade in one-handed mode).
                    2. Stay close to the boss to avoid him spamming ranged attacks (particularly in phase 1).
                    3. Get in one or two hits, then dodge to your left to avoid the counterattack. Try to circle around the boss when dodging, get in a couple of hits, repeat.
                    4. When the boss is charging up for phase two, perform a backstab and visceral attack.
                    5. In phase two, the strategy is essentially the same: Dodge (to your left) through the first swing of the boss's combo, get in a couple of hits, repeat.
                    6. If the boss plants a sword in the ground to summon the flying swords, simply hit the sword to eliminate it. But watch out for the small AOE attack around the sword if you get there as he is finishing the animation.
                    7. His flying/diving attack can be a little tricky to avoid, simply because the camera can makes it hard to see the boss (e.g. if he is directly above you); But try to dodge it if you can, get in a couple of hits, and back off/prepare to dodge his next attack.
                    8. Don't get greedy. If you go for too many hits in a combo, you likely won't have time to dodge his follow-up attack; and his combo in the final phase can be tricky to get out of, once you've been hit.

                      Something strange happened today. I was fighting him with the boom hammer (str build), and the first 3 matches against him, for whatever the reason my backstabs didnt stun him for viscerals during his charge up sequence for phase 2. I was pretty irritated at this fact, so my 4th time fighting him i just went super aggressive and mashed r1 during his first phase. I stunlocked him right into his second phase. He didn't even bother trying to charge, just went right to his second phase moveset. I still just stunlocked him and won. I've never seen him get so assblasted that he doesn't even attempt to charge up and goes right into beserk mode.

                        So, I found you can visceral attack him if your shots are flying off into the air during his second phase. When he flies up to lunge at you, shoot him as he comes down towards you. Works nearly every time.

                          Effff meeee I JUST beat this guy for the first time on my own. Never done that. LVL 99 character with 50 points in Strength and 20 in Skill using the sword part of a maxed out Kirkhammer loaded with attack power gems. Just stuck close and continuously dodged left! Took him down on my second try on my current playthrough! Friiiiick.

                            Use the Loch shield if you have issues with his spells. Get close and parry or backstab your way to freedom. He also is fairly easy to r1 stunlock with a fast weapon.
