Reaching the peak of Arche Abbey represents the culmination of a grueling journey through the puppet-infested streets of Krat. The final confrontation in Lies of P is unique because it offers a dual-layered conclusion. Depending on the choices made regarding Sophia and the final interaction with Geppetto, players may face one or two formidable entities. This analysis breaks down the mechanics, phases, and optimal strategies for Simon Manus and the true final challenge, the Nameless Puppet.

Confronting Simon Manus, Arm of God

Simon Manus serves as the primary antagonist for the latter half of the game, representing the Alchemists' twisted pursuit of evolution. The fight takes place in a vast, circular arena at the tower's summit. He is a massive, heavy-hitting opponent who relies on reach and elemental status effects.

Phase One: The Arm of God

In his initial form, Simon Manus wields a massive mace. Despite his size, his swings have a deceptive rhythm. Many players struggle here because they panic-roll. Simon’s attacks often have a slight delay at the peak of the swing.

  • The Double Horizontal Swing: This is his most common opener. He swings the mace from his right, then follows up with a backhand swing. The timing is slow enough that you can Perfect Guard both hits with minimal practice.
  • The Overhead Slam: Simon raises the mace vertically. This move has high tracking. It is better to dodge toward his left hip rather than backward, as the shockwave has a lingering hitbox.
  • The Leaping Strike: When Simon glows red (Fury Attack) and jumps, he is preparing a massive downward slam. You cannot dodge this unless you are far away; the intended counter is a Perfect Guard. Watch his feet; the moment they begin to descend is your cue to press the block button.

Strategy for Phase One involves staying relatively close. His mace has a long handle, and being right in his face often causes some of his wider swings to miss entirely. Use a weapon with high Guard Regain, like the Holy Sword of the Ark or a heavy Motivity-scaled blade, to mitigate damage if your timing is off.

Phase Two: Simon Manus, Awakened God

After depleting his first health bar, Simon transforms. He gains wings of blue Ergo and his move set expands to include high-tier magic. This is arguably one of the most visually cluttered fights in the game, requiring high focus.

  • Disruption Waves: Simon will cast waves of yellow energy that build up the Disruption status. If this bar fills, you die instantly. It is mandatory to equip the highest-level Resistance Amulet available and carry Special Purification Ampoules.
  • The Hand of God: Simon will reach into the sky, and a massive spectral hand will descend. You will see a golden light on the ground marking the impact zone. Do not try to parry this; simply run out of the circle.
  • The Energy Beams: He frequently flies into the air and fires projectiles. While these can be parried to reflect damage, simply sprinting in a wide arc around him is safer for conserving Pulse Cells.

In this phase, Simon becomes much more mobile. The best windows for attack are immediately after he completes a melee combo with his mace. He often pauses for two seconds after a heavy slam. This is the time to use Fable Arts or a charged heavy attack to build stagger.

The Final Choice: To Give or Refuse

Once Simon Manus is defeated, you descend into the depths beneath the arena to meet Geppetto. This is the pivotal moment that determines the actual end of your playthrough. Geppetto will ask for P's heart to turn him into a "Real Boy."

  • Give the Heart: The game ends immediately. You receive the "Real Boy" ending. There is no final boss fight.
  • Refuse: If you have gained enough humanity throughout the game (by lying and listening to records), P will refuse. Geppetto will then unleash his "failed" masterpiece from the suitcase: the Nameless Puppet.

Refusing the heart leads to the true final boss, which is widely considered the most difficult encounter in Lies of P.

The True Final Boss: The Nameless Puppet

The Nameless Puppet is a mirror of P but without the restraints of a human soul or a standard puppet's programming. It is fast, aggressive, and features two distinct phases that test every skill you have learned.

Phase One: The Stiff Marionette

In the first phase, the Nameless Puppet moves like a broken toy. Its movements are jerky and sudden. It uses a transforming sword that can switch between a short blade and a spear-like extension.

  • The Four-Hit Combo: It usually swings twice, pauses, and then performs two quick stabs. The rhythm is one-two... three-four. Parrying this combo is the fastest way to break its posture.
  • The Spear Thrust: If it retracts its weapon, it is preparing a long-range lunge. The dodge window is tight, but parrying this gives you a massive window for a counter-attack.
  • The Spin Attack: It will spin toward you like a whirlwind. This move consists of five hits. If you hold the block button and tap it in rhythm, you can negate most of the chip damage.

Phase One is a test of patience. Do not over-commit. The Nameless Puppet has very little "poise" in this phase, meaning heavy weapons can interrupt its attacks, but its recovery is fast.

Phase Two: The Awakened Killing Machine

Once it reaches 50% health, the Nameless Puppet becomes a red-eyed demon of speed. Its sword glows with blood-red energy, and it gains massive AOE attacks. This is where most players get stuck.

  • The Scarlet Dash: The boss will sheath its sword and red light will emanate from its hilt. It is about to dash across the arena with a horizontal slash. The timing is near-instant. You must parry the moment you see the flash of light on the blade.
  • The Aerial Dive: It jumps high into the air and slams down, creating an explosion of fire. Sprinting backward is the safest option, but if you are confident, parrying the landing will prevent the follow-up explosion from hitting you.
  • The Infinite Combo: It will sometimes unleash a flurry of 10+ slashes. Unless you are a parry god, it is better to use the Aegis Legion Arm here. Holding the shield up while poking with a spear or rapier allows you to survive this onslaught.

Optimal Builds for the Final Stretch

Beating these bosses isn't just about reflexes; it’s about preparation. By the time you reach the final boss, your P-Organ should be heavily upgraded.

Recommended P-Organ Upgrades

  1. Increase Pulse Cells: You need as many heals as possible. Aim for 10-11 cells.
  2. Enhance Guard Regain: Since you will be blocking a lot, being able to hit back and recover health is vital.
  3. Perfect Guard Stiffness: This makes it easier to stagger the boss after a series of successful parries.
  4. Amulet Slots: You need room for the Blue Guardianship Amulet, the Patience Amulet (Stamina recovery), and the Iron Wall Amulet (Physical damage reduction).

Weapon Synergies

For Motivity (Strength) builds, the Mjolnir Head on the Master Chef's Knife Handle provides a strange but effective balance of high blunt damage and fast swing speed. Alternatively, the Noblesse Oblige is excellent for Phase One of Simon Manus due to its sheer stopping power.

For Technique (Dexterity) builds, the Two-Dragons Sword is the gold standard. Its charged heavy attack has a built-in parry that can stun the Nameless Puppet out of its most dangerous moves. However, it requires high player skill. A safer bet is the Puppet Ripper, which allows you to hit Simon Manus from a distance during his Disruption phases.

For Advance (Elemental) builds, Simon Manus is weak to Fire (Phase One) and Acid (Phase Two). The Acidic Crystal Spear is incredibly effective at ticking down his massive health bar.

The "Secret Weapon": Throwables

Never underestimate the power of items in Lies of P. If you get the Nameless Puppet down to 20% health and run out of Pulse Cells, throwables can finish the job.

  • Shot Put: This is the most important item. If the boss's health bar is white (indicating they are ready to be staggered), throwing a Shot Put will instantly trigger the stagger state from a distance, saving you from having to land a risky charged heavy attack.
  • Cluster Grenades and Thermites: Great for chip damage when you need to keep your distance during Simon's magic attacks.

Tactical Summary

The road to the ending of Lies of P is a test of everything the game has taught you. Simon Manus tests your ability to manage status effects and stay calm amidst visual chaos. The Nameless Puppet tests your raw mechanical skill and timing.

When fighting the Nameless Puppet, remember that it is a puppet, not a human. Its movements follow a programmed logic. If you find yourself dying repeatedly in Phase Two, stop attacking for one life. Spend that entire life just trying to see how many attacks you can parry without swinging back. Once you learn the cadence of its red-trailed slashes, the "impossible" speed becomes manageable.

Victory grants you the "Rise of P" or "Free from the Puppet String" endings, both of which offer much more closure than the default "Real Boy" conclusion. As of April 2026, the community consensus remains: the Nameless Puppet is the definitive final boss experience, and overcoming it is the true badge of honor for any Stalker in Krat.
