  • Why I Chose This: The Aegis is a defensive powerhouse and can work well in almost any situation.

The Aegis Legion Arm in Lies of P offers players a powerful defensive tool that’s much more than just a simple shield. In my opinion, it’s the “safe” option, so anyone can pick it up and easily learn it. Furthermore, it’s effective against bosses and regular enemies alike.

  • Aegis Legion Arm acts like a shield, damaging any enemy that hits it.
  • Perfectly timed, Aegis can parry attacks.
  • It’s unique: parrying with Aegis feels different than a normal block.

How To Get

  1. Collect materials, especially a Legion Plug.
  2. Visit Hotel Krat.
  3. Find the Venigni Machine inside the hotel.
  4. Use the Legion Plug with the Venigni Machine to create Aegis, the best Legion Arm in Lies of P.
  • Protects against tough enemies and bosses.
  • For those who aren’t great with perfect blocks, Aegis is a lifesaver.
  • Great for players who like a counter-attack style.

Ideal Legion Arm against puppets.

  • Why I Chose This: 60% of the in-game enemies are puppets, who are especially vulnerable to electric damage, which is where the Fuliminis shines.

Fulminis Legion Arm in Lies of P is an electrifying addition to a player’s arsenal, giving them the shock factor in battles.

  • The Fulminis Legion Arm sends out electric shocks to enemies.
  • Upgrading it enhances its capabilities significantly.
  • The Fluminis Legion Arm is especially powerful against Puppet-type enemies.
  • Flamberge is good for infected, but Fluminis shines against puppets due to their weakness in electricity.

Unfortunately, throwing objects in Lies of P are extremely overpowered, so the Fulminis does get overshadowed by the Throwing Cell. If you’re keen on killing puppets, the Throwing Cell is a much better alternative, in my opinion. It’s faster, has more range, and you can reserve your Legion Arm slot for some other option.

How To Get

  1. Defeat the Scrapped Watchman in Lies of P located in the Krat City Hall.
  2. Obtain the Overcharged Storage Battery from the defeated opponent.
  3. Visit Eugénie at Hotel Krat.
  4. Give the Overcharged Storage Battery to get the Fluminis Legion Arm in Lies of P.
  • Ideal against puppet enemies.
  • With upgrades, the Fluminis Legion Arm becomes versatile.
  • Makes exploring the open world easier and more enjoyable.
  • Starting version has a limited range.
  • Without upgrades, you’re rooted while charging.
  • Too reliant on upgrades.
  • Not the best option against monster enemies.

3. Puppet String

Stepping away from the melee-heavy focus of Lies of P, the Falcon Eyes Legion Arm stands out as a powerful ranged alternative from my experience. Think of it as having a cannon within your arm. It’s a unique game-changer, especially when distance matters.

  • Explosive Bullets: Its main function is shooting exploding projectiles.
  • Range Advantage: A rare opportunity in the game to deal damage from a safe distance.
  • Upgrades: Enhances firepower by shooting more bullets.


  • First Upgrade: Increases the explosion radius, making it apt for crowd control.
  • Second Upgrade: Fires a follow-up shot immediately after the first.
  • Third Upgrade: Adds the ability to shoot while dodging, boosting adaptability.

How To Get

  1. Go to Hotel Krat.
  2. Locate the Venigni Machine.

The Flamberge Legion Arm ignites the battlefield with its fiery prowess in Lies of P.

While it shares similarities with the Fulminis Legion Arm, the key distinction lies in its elemental affinity: it’s all about flame rather than electric power. From my experience, most other Legion Arms required practice and certain playstyles. The Flameberge doesn’t have the same limitations but still has equal or better firepower.

  • Elemental Power: Emits intense flames, offering a unique way to counter the puppet adversaries.
  • Upgrade Perks: Enhanced fire range, longer firing duration, and the ability to cause explosive damage after sustained firing.


  • First Upgrade: Boosts the range of the fiery assault.
  • Second Upgrade: Intensifies damage after continuous use of Flamberge.
  • Third Upgrade: Creates a powerful explosion after a sustained firing duration, though it requires skillful execution.

How To Get

  1. Proceed to the Venigni Works Control Room.
  2. Defeat King’s Flame, also known as Fuoco in Lies of P.
  3. After the victory, receive the High-powered Flame Amplifier item.
  4. Return to Hotel Krat.
  5. Find the Venigni Craft Machine.
  6. Craft the Flamberge Legion Arm using the High-powered Flame Amplifier.
  • Practical and easy to use.
  • Extremely effective against monsters.
  • Applies DoT.
  • Somewhat less exciting.

My Tips For Effectively Using Legion Arms

Legion Arms become a crucial part of your arsenal towards the late-game phase of Lies of P. If you want to utilize them properly, make sure you dedicate yourself to just one Legion Arm and spend your Legion Calibers on that specific Legion Arm. Next, always look out for Legion-focused enhancements when unlocking new P-Organs using your Quartz.
