Sulyvahn's Beast

Enemy Type Beast





Resistance ??
Immune ??

Sulyvahn's Beast is an enemy in Dark Souls 3.


Enemy Description

  • A ferocious beast that attacks relentlessly.
  • A head similar to that of a crocodile with three pairs of eyes and numerous teeth. Covered in grey fur, from its head to its curved tail. The ribcage has been torn open and shudders when the beast breathes.
  • None of them respawn after death.
  • The two in front of McDonnell have 2721 health in NG.


Combat Information

  • Attacks mainly with bites, snapping at the player. Has a running charge that grabs the player and can result in instant death, to avoid it you should roll sideways slightly sooner than you would think. The attack has a wider reach than expected.
  • If the player is behind or beside this beast it will swipe its head to hit the player and to face the player. It can be hard to evade but it has an obvious wind-up. It will generally do two swipes, from one side to the other.
  • Player will generally be charged by the first beast on the bridge, but if one is close enough, it will enter its normal attack patterns instead.
  • Contact with the exposed ribcage on the underside of the beast often creates a knockback effect, interrupting both your blocks and attacks.



  • Irithyll of the Boreal Valley
    • First encountered upon crossing the bridge into Irithyll. If not slain here, it will jump off the bridge and fight you in the water area below after crossing underneath.
    • Two can be found behind an illusory wall in a small room just before the Silver Knight archers. They protect access to the Aldrich Faithful covenant and the Ring of Favor.


Notes & Tips

  • They are EXTREMELY susceptible to bleed. Dorhy's Gnawing can deal upwards 800+ damage per cast at 30 FTH.
  • VERY weak to fire: 2-3 Great Chaos Fire Orbs will put them down pretty quickly.
  • It's susceptible to poison. At SL 31 with 22 intelligence a single application of Poison Spores from the Storyteller's Staff will kill a beast in front of McDonnell. Application can be difficult however due to their speed and unpredictability.
  • All of Sulyvahn's Beasts are unique targets. Dedicated combos kill them quickly, but they have equally dangerous attacks of their own, and can punish reckless behaviour.
  • Roll sideways to stay close when dodging, and come up swinging at them to get damage in before they attack again. Don't trade blows, and don't extend your combos.
  • Without a high investment in Endurance (~30) and/or top notch endurance recovery management (don't hold your shield up when not being attacked for faster regeneration), shields can be difficult to use effectively in this fight as some attacks/combos from the beasts deplete large amounts of stamina. Shield-breaking during this fight will lead to almost certain death.
  • Attacking it from their sides proves useful but beware of its head swipe, it can be difficult to evade.
  • When it breathes lightning it is best to hug its chest or sides. Once the beast breathes lightning they won't change their direction to follow your character, making it easy to evade and punish with one or two good hits before it recovers.
  • Its head is a weakness, like most large enemies
  • A single Great Heavy Soul Arrow to the face after it completes it's initial charge and flop will result in the beast rearing back for a Critical Hit. Simply run up, stab it with an implement of your choice and you will do Massive Damage. The beast then falls backwards and begins flailing. Like everything about this creature the flailing deals damage and can kill you. Either continue blasting it to finish it off or wait for it to slow down and get a swing or two in. It will get back up after this if you've failed to finish it. Differences in NG+ apply until testing can happen.
  • Because the McDonnell fight is very difficult, it is advised to use a bow to lure one of the beasts.
  • Alternatively, you can quickly dispatch them by waiting for their initial plunge and hitting them hard on the nose. This will cause them to go into a reposite state for additional damage. Afterwards, they will be vulnerable for a final attack.


Irithyll: Entrance Bridge Strategies

  • As soon as it spawns for the first time, this Sulyvahn's Beast takes several seconds to roar and announce its presence.  During this moment, it is very easy to run up and unleash your heaviest attack on its head.  With enough damage, it will lean backwards and go into a riposte-able state.  When I used this strategy, I had two-handed a +1 Demon's Greataxe (~400 AR) and hit it with Demonic Flare for an easy riposte opportunity.
  • An easier way is to count 4 decorated, flower pillars on the bridge, as soon as you reach the fourth one the beast will appear. You can then dip in and out of the entrance, the beast will attempt to disappear once you step out the gate, and will not attack even if it sees you. That technique provides an opportunity to get some hits in. Repeat until it's dead.

Irithyll: Bridge Underside Strategies

  • If you don't defeat the first one you encounter on the bridge in Irithyll of the Boreal Valley, and you encounter it again in the water below, there is a simple strategy to defeating it by using the environment to your advantage. In the northern corner, just before you reach the stone floor and manor in the distance, there is a rounded area surrounded by the rocks, a cul-de-sac of sorts. In this rounded area is a crack in the rocks on the right side just big enough for your character to fit into. If you stand at the very back, the monster cannot reach you even though he will try to. From here you can whittle his health down with ranged attacks or carefully timed melee attacks. Block his electrical attack and don't get close enough for him to reach you, and eventually, you will defeat him.

Irithyll: Water Reserve Strategies

  • Skull Ring Strategy
  • A solid strategy is to stagger/riposte. Lure one over with bow, then climb up the ladder immediately, when it begins to walk into the wall, press (climb)+(jump) the jump down the ladder, aiming for his head, and this should cause him to fall back and giving us a riposte. Note that the beast can reach up to the ladder to a certain height, also being able to finish it in one combo is the best possible outcome.
  • A viable strategy for sorcerers is to apply Poison using a Storyteller's Staff, Hidden Body, and Slumbering Dragoncrest Ring to get close enough without notice. After using Poison Spores the beast will move toward you to investigate the spell casting placing it in the poison cloud. Moving backwards will ensure it does not notice you. If a single casting fails to apply poison simply repeat.


  • It has a similar look to the Egyptian demon Ammit, whose name means Soul Eater.
  • Sulyvahn's Beast belongs to a group of crocodile like monsters inspired by Berserk's Beast of Darkness - read here.
  • Drops 12000 Souls.
  • If the beast survives after a riposte, it will cross its hands over its stomach, seemingly in prayer, and will become "friendly" until attacked again.
  • Its underbelly looks similar to that of the Gaping Dragon.
  • Can be staggered and riposted.
  • Is nearly identical to the Watchdog of Old Boss from Bloodborne

      They are nothing like the Watchdog of the Old Lords from Bloodborne other than some superficial similarities. That last line in the "trivia" section needs to be deleted.

          Also, you don't need the Slumbering Dragoncrest Ring or Hidden Body to deal with the two in McDonnell's room. If you hug the left wall and move slowly, you can get into position to charge attack the first beast's head without aggroing him and finish him off without pulling the second one. You can remove or lighten your armor to make less noise.

            Regardless of your stats or build, a Bandit's Knife with Carthus Rouge will make extremely short work of these. They really are that weak to Bleed and it will proc on every second or third hit. Same thing goes for Monstrosity of Sin.

              The one on the bridge isn't too bad, but the two in the secret area are tough as nails. I didn't realize the bridge one will appear under the bridge if you don't kill it on top of the bridge and was surprise attacked once, a bit amusing.

                They are extremely easy and would need to have double the health, I killed them on my first try with lvl18+2... that was fun but the fight was very short. I expected to die, but they are so weak to blood that they died almost instantly.

                  Pull one at a time with a bow. Use a charcoal pine resin and a shield with high stability. Hit them in the face a lot and they flop back for an easy critical attack. They're fast, and they seem intimidating, but just block their physical attacks until you can get good hits in. Actually pretty easy kills if you don't psych yourself out of it.

                    I found an easy way to take them. I'm a Pyron with a Storyteller Staff. I went for the first visible one by walking toward the far right pillar. It saw me and aggroed on its own (the other stayed off to the left) As it saw me I kept the pillar between us and started using the poison from the staff (lasts longest for me so far). Two blasts were enough to poison it, and as it went into an attack animation against the pillar I rushed for the ladder and started climbing up. I walked out of the area and went off to kill other enemies elsewhere (in this case hose fire casting guys along the wall outside). Oncew I cleared them out I went back and the beast was no longer aggro but where it started. Repeat as before. Aggro, poison, run and climb. The second time was enough to kill it. You can them go for the other one, and either climb out like before, or just keep a pillar between you and wait it out (if you are confident enough). Easy win.

                      What a terrible enemy. Not hard to defeat, but just annoying to fight due to the unrelenting aggression. It's almost as if the design team got lazy and just started ripping enemies out of Bloodborne and placed them all over this game. Lazy design.

                        Sulyvahn's beast is the same creature as the watchdog of the old lords from bloodborne. The watchdog is on fire, which is a signature of the Lord's of cinders. A watchdog is used to protect things of important, and you have to get past sulyvahn's beast to reach 3 quarters of the lords

                            One chaos bed vestiges is enough to stagger him and leave him open to critical hit animation Two chaos bed vestiges is enough to kill him, at worse leave him with less than 10% hp.

                              what i did to get them both : -equip the slumbering dragoncrest ring (no noise ring) -cast hidden body -once close enough, cast chaos bed vestiges (did 1200 damage with a 26/40 int/faith build) -cast it a second time before he reacts (normal spell speed cast is enough) -now he should be low life and/or opened for a riposte. Finish him off on a single attack -use an ashen estus flask and repeat for the other beast
