 Combat Information

The Watchdog is immune to fire damage. A lot of its attacks deal fire damage, in fact all attacks seem to deal fire damage, but they are all avoidable. So fire resistance, while helpful, is unnecessary. Ranged damage (Simon's Bowblade / Blacksky Eye) is effective in this fight. Saw weapons are also effective as The Watchdog's weak to Serrated.

When you enter the room it will likely use its charge attack so be prepared to dodge. It constantly moves toward you slowly so most of its attacks will be the Flame Swipe and Bite Combo. After using its bite combo, it will return to a neutral stance; you can use a vertical overhead attack to damage the crested plates on top of its head. After taking a few hits to the head, the defensive plate will become damaged and further attacks to this area will cause additional damage. If it does Flame Swipe instead, you can dodge through the flames, but if you are close to it, it will use the attack again with its other claw. It can transition into a Bite Combo pretty easily from Flame Swipe so it's best to dodge away and reset its and try for a Bite Combo. Because these attacks are very easy to avoid, this strategy is optimal. At 50% health it does its Explosion move which can kill you, if get caught in it.

It now moves at you much more aggressively and is just as likely to use Snapping Bites and its Bite Combo--generally it seems to use Snapping Bites if you are almost directly in front of it, so try to stay at its side  to goad out a Bite Combo.

Keep trying to bait it into using Bite Combo and avoid its Explosion. When it uses an attack, you will see its throat swell up like a toad. If you hit it enough times while it's swollen, you will stagger it. However, if you don't manage to pull off a stagger, you'll likely get hit with its attack.


  • Striking its knees enough or hitting them with a strong charge attack will cause them to shatter, briefly stunning it. Attacks on a broken leg will deal increased damage, however breaking a leg will seem to increase the frequency of certain moves.
  • Its head can also be broken with enough damage, causing it to take much more damage from attacks.
  • While stunned be very careful that you don't stay too close to it. When it gets up it will do a burst of flame that deals high damage, followed by a charge.
  • Always dodge in the direction that it swings its head.
  • Alternatively, bait it to swing its head or bite, and then reach it by dash jumping, leave a couple swing before it slams the ground with AoE explosion.
  • Be very careful when attacking it, because at any point an attack could trigger it to immediately cancel its current attack and perform a charge attack in front of it. Provided you're to the side and not too close to it, you should be safe

Easy Cane Whip (Whip Mode) Technique for Defiled Chalice Level 2 (By FalseShadows):

The key is to stay close, to only trigger its single sweeping bite attack. Watch out for the attack, evading accordingly (Backing a step or two should be enough, no need to jump backwards), as soon as the attack animation is about to finish (bringing its head back to normal position), do an R2 attack and IMMEDIATELY take 2 sidesteps to the right as it will do its Charge Attack. The Charge attack should miss and the lock-on might be disengaged. Face it lock-on and close the distance right away and repeat the attack luring. This is a guaranteed hit to the head every time, if the distance is managed correctly.

As you are approaching 40-50% HP mark, you will injure its head, marked by the animation. This is a Visceral Attack opportunity, so be sure to line yourself up well against its head to trigger. Notice that injuring its head increases the damage of subsequent hits dramatically.

After this, is when things start to get dicey. It will do a Flame Burst attack, which you can avoid by backstepping twice/thrice depending on your position in the arena; after the attack, it will start to move faster. The luring method is pretty much the same, except the enemy will start to chain its Sweeping Bite attack up to 3 consecutive strikes, depending on how close you are. You can still aim to hit after the first Sweeping Bite, but should the dog chain its bites, your attack will miss and you have a small window of time to backstep or risk being hit by the succeeding bites.

Luckily, the chaining of the bites are slow, so if you miss the first strike opportunity, evade the second and third sweeping bite and R2 strike as the third Sweeping Bite (The upward sweeping one) animation finiits and the attack should hit the head as normal. Remember to double/triple backstep once it starts to cue its Flame Burst (it changes its stance) it seems to do it more often as it is near-death. Repeat luring as soon as the Flame Burst finiits. It should be down in no time without you taking any damage. (Done at Lvl 127 with 35 Vit, 50 Skill and a +10 Cane Whip.)

Holy Blade+9 and Evelyn+9 strategy (by Mr. Fluffybottom)

This strategy yields the quickest damage that I've found (high skill + bloodtinge preferred). Lock on and stay in front of it. You will be focusing on its head. Keep Ludwigs Holy Blade in 1-handed mode for quicker attacks. Bait its biting attacks, paying close attention to whetits it is doing a single or double bite. Wait until the last bite and dodge-step forward and strike it once in the head with the holy blade. Backstep out of range and repeat. If you're quick enough and have its animations down you can usually hit it once, before the bite begins and again when it finishes. In between bites, it will occasionally try to pepper you with small fire blasts from its claws and mouth. Backstep repeatedly to avoid these and then return to baiting its attacks. It will also occasionally vomit up a puddle of magma.

As it begins gagging, you can rush in and hit it a couple times before backing off. Be mindful of the puddle's location afterwards as the damage and stun-lock from it will wreck you. If you have enough phys %-up gems on your holy sword you should be able to break its head in time for stage 2 by focusing attacks on it. When this happens, it staggers. Hit it no more than 2 times and back off. It will do an AoE attack upon stagger recovery, which can easily one-shot you if you get too greedy. It will now take increased damage from all attacks on its head.

Upon entering stage 2 (~70% HP) it will erupt flames from its body and become more aggressive. Its bites will often be a 2-chain instead of a single so watch for the telltale movement before approaching for a hit. In addition, it will begin including a 3rd bite attack occasionally where it will snap forward at the player in a diagonal motion. This always goes to the player's left, so sidestepping to the right allows for 1-2 hits before it pulls back. Its pepper breath attacks will happen more often now and include more hits, so watch yourself. Additionally, it will begin using is AoE attack occasionally instead of just when staggered. Backpedal when you see the cinders swirling around it or die. Finally, when it approaches stage 3 it will begin using a charge attack (the same attack it likely opened the fight with). It announces this by stopping, spreading its legs, and roaring. It then swings its head down and lunges forward. This is a do or die moment for this fight. You can avoid this by sidestepping to the right in the moments before impact. If you dodge too early it homes in on you.

Alternatively, you can take these charges as an opportunity to parry if you've broken its head already. Pay close attention to its movements when it sets up for the charge. As it roars and brings its head down titse's a slight pause witse it tightens up its legs before lunging at you. As soon as it begins to lunge after this you can shoot it in the head to parry. It will fall to its knees and be vulnerable to a visceral attack to the head. Whetits you dodge or parry is up to you and how comfortable you are with your timing. If you miss the parry the charge may easily one-shot you or leave you with a sliver of health at most. High risk, high reward. Alternatively, for Arcane users, once it has 50% HP left, spamming A Call Beyond combined with Bloodbullet will make this fight almost trivial.

Finally around 30% HP it enters stage 3. It erupts flames again and speeds up all of its movements. It will become extremely aggressive and begin charging more often. It will also begin using a more powerful AoE more often. It has more range than before. Backpedal as far back as possible when you see it charging it up. Being near the center WILL kill you. Its bite chain will always be 3 hits now and it will tend to use its fire blast attacks more often. They will have increased range and duration so be wary. At this point in the fight it may be wise to focus on shooting its head when he's walking towards you if you have any bone ash. This will speed up the last portion of the fight up. Beyond that, just keep peppering it with hits in between its attacks and you should be victorious.





Phase 1 Interrupt Notes
Swipe Bite No A series of wide, horizontal bites triggered when close to its front or side. The reach of this attack is deceptively large and is possible to get hit when in standing in flanks.
Flame Wave Swipe No Left swipe sending a wave of fire outward. Quickstep eitits to the side or through the wave.
Flame Bark Combo No Barks quick bursts of fire ahead. Back away during its long build-up to avoid this.
Lava Vomit No Vomits lingering pools of lava ahead. Back away during its long build-up to avoid walking into the lava pools.
Flaming Charge No Lights up and charges; quickstep to eitits side and out of its way. Hitbox is deceptively large and is triggered when entering boss room, cooperators should wait upon entering.
Pounce Attack No Pounces from hind legs with heavy tracking. Dash or quickstep forward past it while it's airborne.
Stomping Combo No Stomps multiple times with its front and hind legs when standing against them. Quickstep backward to avoid.
Phase 2 Interrupt Notes
Double Flame Wave Swipe No Same as the Flame Wave Swipe, but followed by a delayed second hit from the right paw. Quickstep left twice to move out of the second's range.
Phase 3 Interrupt Notes
Explosion No Absorbs heated particles before using a massive explosion. Gain as much distance possible by repeatedly quickstepping backward.

      I was worried this thing would be difficult but it was one of the few bosses I slayed my first attempt. I kept running around the pillars back and forth catching it from behind.

        This boss at Defiled Chalice isn't big deal. He is fair in some sorts but -50% HP debuff is joke. Like no mistakes allowed. Hate it.

          Executioner's Gloves will stagger his Flaming Charge. Not sure how to time it yet. I get lucky and send out my EG attack before his charge animation and as he is charging he gets hit and staggered. Will stop his charge dead in tracks. Attack will hit you if you connect EG as he connects his charge (like all parry/reposte timed too late)

            Staying in front of him, with moonlight sword and R2 projectile every time the does the bite makes this bossifight a joke. When you stagger him the projectile goes from 300 to 1.2k of damage (50 arcane) just stay put of range blood bullets and heal. Only attack you have to learn dodging to win is the charge.

              idk why but this thing gives me the feeling that Bloodborne's and Dark Souls' worlds are linked in some way
              Same with the Keeper of the Old Lords, or at least I think that's his name

                For anything having trouble I have a few tips for you:
                1: Learn his attack animations, after you learn the charge attack animation and the one where he bursts a few flames out, you don't have to be worried about being one shot as much.
                2: Use a long weapon, I did it with the rifle spear.
                3: Bait out his head swinging attack and use a charge attack while it's resetting. Keep backing up and baiting out waiting for that attack.
                4: He takes a fair bit of damage from guns if you use them while he's doing the burst flame attack.
                5: Take your sweet ass time with him, this isn't a boss you want to be charging in constantly attacking his legs because a lot of his attacks will punish that if you're not extremely careful.
                6: Don't get greedy! When he's puking flames, you don't always have to attack him if you don't think you have enough time, and if you think you do, only hit him once or twice and back away.

                These things are what got me thru the fight, it took me about an hour to get him down, but I feel like I could do it easily now that I've learned most of what there is to learn about him.
                Just take your time and stay calm, you'll get it eventually.

                  Just solo'd this flaming bitch today with the LHB. My palms are still sweaty. Probably my favorite boss battle in the game so far.

                    Easily doable with Simon's bow on defiled chalice. Just did it on bow mode only. Started doing ~350 dmg at the beginning of the fight until i shot it while he started to puke fire. It then staggered it and from that moment on, until he went to last phase, my bow went from 350 to 1k dmg. Just be careful with its charges and sometimes let him get near you so he can do his head swipe animation. Than roll back a couple of times and keep firing with charged r2. And also keep sacrificing health to get the +5 bullets, but always use vitals after. Bow max level, 50 skill and 38 bloodtinge.

                      I ended up cheesing this dude by baiting his head attacks and using an overhead R2 with the two-handed Hunter Axe. It's great because if you maintain your spacing you can get one in every time and still be out of range if goes for the double snap. Patience is key.

                        I actually found this boss to be easy, but exhilarating. Keeps you on your toes, but has obvious tells. One of the few bosses where being less aggressive is probably better.

                          If anyone wants to team up against this thing add me xXAuRaCoXx and put the name of this boss. I’m gonna avoid doing it until I have someone else.

                            This boss doesn't drop that amount of blood. At least not anymore, just killed for something about 2000 bloods.

                                The Defiled Chalice version was the most demoralizing fight in the game. After the first few deaths I didn't even get annoyed when I died. I just felt tired.

                                I finally ended up summoning Queen Killer after dying for three days. It's the first time I summoned anyone for a fight

                                  I had the hardest time with this guy in the Defiled Chalice until I decided to just keep my distance and strategically smack his elbows with a fast weapon. As long as pace your attacks and don't get caught under him (and get killed by Camera Boss™), he's pretty predictable; greed and aggression will earn you many a one-shot trip back to the lamp. I was actually kind of shocked how easy it was when I decided to just take it slow. Having a bloodtinge build, Evelyn +10, and a good supply of Bone Marrow Ash helped speed up the process, shooting at his injured limbs at a safe distance and getting massive damage off each shot.
