You're stuck. We’ve all been there, staring at the "Stargazer" in the Hotel Krat, wondering if we actually have the reflexes for this or if we should just go back to playing something more relaxing. Neowiz didn't just make a "Soulslike" with Lies of P; they made a rhythm game disguised as a Victorian nightmare. If you can’t parry, you’re dead. If you can’t manage your stamina, you’re dead. And if you’re fighting the Lies of P hardest bosses without a clear strategy, you’re definitely going to be seeing that "You are Dead" screen more than the actual gameplay.
It’s not just about "git gud." It’s about the fact that this game throws massive difficulty spikes at you that feel genuinely unfair until the moment the mechanic finally clicks. Honestly, some of these fights aren't even about skill—they're about your patience and whether or not you remembered to upgrade your P-Organ.
The Puppet King and the Romeo Problem
Everyone remembers their first time hitting the Estella Opera House. It’s beautiful, it’s creepy, and then you meet the King of Puppets. The first phase is a giant, clunky mess of metal that teaches you the importance of positioning. It’s huge. It’s intimidating. But it’s actually the easy part. Once you break that shell and Romeo climbs out, the game shifts gears entirely.
Romeo is fast. Like, "did I accidentally turn on 1.5x speed?" fast. He’s the first real wall most players hit because his fire dance—that long, sweeping combo where he lights his scythe on fire—can end a run in three seconds flat. If you try to dodge away, he catches you. If you try to block, the fire chip damage eats your health. The secret? You have to dodge into him. It feels counterintuitive to throw yourself at a flaming blade, but dodging to his left side (your right) bypasses most of his hitboxes.
Most people rank him among the Lies of P hardest bosses because he demands a level of perfection that the previous bosses like Andreus didn't require. You can’t just tank Romeo. You have to dance with him.
Laxasia the Complete is a Literal Lightning Storm
If Romeo was a wake-up call, Laxasia is a funeral service. Found at the top of Arche Abbey, she is widely considered the absolute peak of the game's difficulty. Why? Because she has two distinct phases that require completely different mindsets. Phase one is all about heavy, delayed swings. She’s tanky, she hits like a semi-truck, and her attacks have these weird pauses that mess with your parry timing.

Then Phase Two happens.
She sheds the armor, grows wings, and starts lobbing lightning bolts at you from the air. This is where most players lose their minds. The trick—and it’s one the game doesn't explicitly tell you—is that you can actually parry those lightning bolts back at her. It does massive damage and builds up her stagger bar. If you aren't doing this, the fight is almost impossible. You’ll spend the whole time chasing her while she zips around the arena like a caffeinated fly. She is the ultimate test of the Perfect Guard mechanic. If you haven't mastered the timing by now, Laxasia will make sure you never see the ending.
The Nameless Puppet: A Secret Test of Skill
You can actually skip this boss, but why would you? If you choose to give GEPPETTO your heart, the game ends. But if you refuse, you face the Nameless Puppet. This guy is the "true" final boss and he is a nightmare.
He doesn't use magic. He doesn't have a giant health pool. He just has a sword and a really bad attitude.
What makes him one of the Lies of P hardest bosses is his sheer aggression. In the second phase, his twin blades have reach that covers almost the entire arena. He leaves almost no room for healing. If you back off to pop a Pulse Cell, he’s on top of you before the animation finishes. The fight feels like a duel from Sekiro, requiring constant, rhythmic parrying. Use the Aegis Legion Arm here; it’s a lifesaver for blocking those fast multi-hit combos while you look for a window to poke him.

Simon Manus and the Chaos of Phase Two
Simon Manus, the Awakened God, is a weird one. His first phase is actually kind of slow. He swings a giant mace-thing that has a lot of "weight" but is predictable. But once he transforms, the screen becomes a mess of blue magic, explosions, and giant hands falling from the sky.
The difficulty here isn't necessarily technical skill; it's visual clutter. It’s hard to track his physical movements when there’s a giant magical explosion happening right on top of your head. Most players find him frustrating because it feels like you're fighting the camera as much as the boss. Keeping your distance is actually a trap here. You want to stay close to his legs, even if it feels dangerous, because his ranged magic is much harder to deal with than his physical swings.
Green Monster of the Swamp: The Mid-Game Wall
We need to talk about the Swamp Monster. This boss is the reason many people quit the game in the middle. It’s gross, it’s fast, and it inflicts Decay, which eats your equipment durability and your health.
Phase one is okay—mostly just dodging a charging beast. But Phase Two sees the monster inhabit the body of a scrapped puppet (specifically the Scrapped Watchman from the beginning of the game). It gains all those electric attacks but keeps its own chaotic movement. It’s a "remix" boss that catches you off guard because you think you know the moveset, but the timing is just slightly different enough to ruin your parries. Fire damage is your best friend here. If you aren't using the Flamberge arm or fire abrasives, you're making life way harder for yourself.
Why Your Build Might Be the Problem
In Lies of P, your stats matter, but your P-Organ upgrades matter more. If you're struggling with the Lies of P hardest bosses, check your upgrades. Did you get the "Link Dodge"? Did you upgrade your "Pulse Cell" capacity? These aren't just perks; they are fundamental changes to how the game plays.

A "Motivity" (strength) build lets you block more effectively because heavier weapons have higher Guard Regain. You can miss a parry, take the block damage, and then hit the boss back to get your health back. A "Technique" (dexterity) build requires much better dodging and parrying because your weapons don't block nearly as much damage. If you're hitting a wall, maybe head back to the Hotel and respec at the Gold Coin Fruit tree. Switching from a fast dagger to a heavy wrench-head on a police baton handle might be exactly what you need to break a boss's posture.
The Role of Specters: No Shame in the Game
There’s a segment of the community that says using Specters is "cheating." Ignore them. The game provides Star Fragments for a reason. If a boss like the Black Rabbit Brotherhood—where you're getting ganked by four different NPCs at once—is ruining your fun, summon help.
The Black Rabbit Brotherhood (especially the second encounter) is designed around chaos management. Having a Specter to distract one or two of the siblings while you focus on the Eldest is a perfectly valid strategy. These fights aren't always about a fair 1v1 duel; they're about survival in a city that’s gone to hell.
Actionable Strategy for Victory
- Perfect the Parry, but Don't Rely on It: Some attacks are better dodged. If a boss has a multi-hit combo that pushes you back, dodging through the last hit often puts you in a better position for a counter-attack than parrying the whole thing.
- Use the Cube: The Wishstones can give your Specter more health or elemental damage. In the late-game fights against Laxasia or Simon Manus, a buffed Specter can be the difference between a win and a 2% health wipe.
- Legion Arm Synergy: Don't just pick one and stick with it. The Falcon Eyes is great for finishing off a boss with low health from a distance, while the Puppet String's final upgrade allows for a massive plunging attack that deals huge stagger damage.
- Throwables are OP: Seriously. If you're struggling with the final 20% of a boss's health bar, start chucking Shot Puts, Thermite, and Electric Throwables. They scale well and can finish a fight while you stay at a safe distance.
- Check Your Weight: Stay under 60% weight capacity. If you're "Slightly Heavy," your stamina regeneration slows down significantly. In a game where every millisecond counts, you need that stamina back as fast as possible.
Stop treating Lies of P like Dark Souls. It’s its own beast. It wants you to be aggressive, it wants you to parry, and it definitely wants to see you fail a few dozen times before you earn that victory. Go back in there, change your weapon head, and stop panic-rolling. You’ve got this.
