TL;DR
- The Electro-Mecha Longsword drops from the Machina Knight boss at Marni’s Outpost in Deleysia.
- No quests needed — just go there and fight.
- The boss has two phases: longsword first, spear second.
- Phase 1: parry and counter. Phase 2: dodge and evade.
- The sword has 27 Attack Damage and Lightning Affinity but cannot be upgraded.
- Best attempted in mid-to-late game.
The Electro-Mecha Longsword is one of the most unique two-handed weapons you can find in Crimson Desert. It deals lightning damage on every hit, which means you can stun and electrocute enemies with each swing. That alone makes it stand out from most weapons in the game.
But you don’t find this one in a chest or buy it from a shop. You have to earn it. Specifically, you need to beat the Machina Knight — a two-phase boss that will punish you hard if you’re not ready.
Here’s exactly where to go and how to win.
Electro-Mecha Longsword Stats
Before we get into the fight, here’s what you’re working with:
- Weapon Type: Two-Handed Longsword
- Attack Damage: 27
- Special Property: Lightning Affinity (every hit deals lightning damage and can stun enemies)
- Can it be upgraded? No
- Accepts Abyss Gears? No
It’s a fixed weapon. What you see is what you get. But the Lightning Affinity is what makes it worth the trouble. The stun buildup alone is a huge advantage in fights, especially against bosses and groups of enemies.

Where to Find the Electro-Mecha Longsword — Marni’s Outpost Location
The Electro-Mecha Longsword drops from the Machina Knight, found at Marni’s Outpost in the Deleysia region.
To find it:
- Open your world map and look for the word “Gorthak.”
- Marni’s Outpost sits just north of the “K” in Gorthak.
- It’s in the far eastern part of Deleysia.
The area is filled with dangerous robots before you even reach the boss. Don’t rush through — clear them carefully so you’re in good shape when the main fight starts.
There are no quest prerequisites. You can go there at any point in the game. That said, this is a tough two-phase boss, so we recommend going mid-to-late game when your gear and skills are in better shape. If you’re still building your early setup, take a look at the best items to grab early in Crimson Desert before heading out.
Once you arrive at the outpost and enter the arena, the fight begins automatically.
How to Beat the Machina Knight — Full Boss Guide
The Machina Knight is a two-phase fight. The strategy that works in Phase 1 will get you killed in Phase 2. Pay attention to the shift.
Phase 1 — Machina Knight with Longsword
This phase is manageable once you learn the rhythm.
The Machina Knight opens with his longsword and hits you with a three-hit combo. Every swing in that chain can be parried. Press L1 at the right moment — whether you’re using a shield or your weapon — to block and break the combo.
After a successful parry, you get a small window to attack. Keep your hits short and fast. Don’t get greedy. One or two quick strikes, then reset to a defensive stance and wait for his next combo.
Turning Slash (R1 + R2) is your best friend here. It deals solid damage and actually cancels the Machina Knight’s attack animation mid-swing. A solid loop for this phase:
- Use Turning Slash
- Parry the counter
- Turning Slash again
- Repeat
Stay patient. Don’t try to force damage. Let him come to you, parry, then punish. Keep doing this until he drops to around 50% health, and Phase 2 begins.
Make sure your stamina is solid going into this fight. If you need help, our guide on how to get max stamina will help. And if your health pool feels thin, check how to get max health in Crimson Desert too.
Phase 2 — Machina Knight with Spear
This is where the fight gets difficult.
Once he hits 50% health, the Machina Knight drops the longsword and picks up a spear. Everything changes.
He becomes much faster and far more aggressive. He hits harder and gives you fewer recovery windows. If you try to parry him the same way you did in Phase 1, you’ll burn through your stamina fast and leave yourself completely open.
Switch your approach entirely:
- Stop relying on parries. Parrying spear attacks is technically possible, but it drains your stamina too fast. Save parries for emergencies only.
- Dodge-roll everything. That becomes your default response to all his attacks. Evade and reposition constantly.
- Watch for his invulnerable phases. During these windows, the Machina Knight fires seeking cubes that track your position. You cannot block them. Dodge-roll through them and keep moving until the invulnerability ends.
- Build his stun meter. Keep landing attacks — especially Turning Slash — to fill up his stun meter. Once he’s stunned, that’s your moment to deal real damage.
The biggest mistake players make in Phase 2 is playing it like Phase 1. That gets you killed. Stay mobile, stay patient, and let the stun meter do the work.

Getting the Electro-Mecha Longsword
Once the Machina Knight goes down, the Electro-Mecha Longsword is added to your inventory automatically. No extra steps, no crafting, no turn-ins needed. Just equip it and go.
Every melee hit you land with this sword triggers the Lightning Affinity effect. That means consistent stun buildup against almost everything you fight. For mid-game content especially, this weapon punches well above its weight.
Yes, it can’t be upgraded and doesn’t take Abyss Gears. That does limit how far it can carry you in the very late game. But for the bulk of Crimson Desert’s content, it’s a reliable and satisfying main weapon — and it just feels great to use.

Tips Before You Go
- Gear up first. Don’t go here as a fresh player. The robots before the boss and the boss itself will overwhelm you if your attack and defense levels are low. Check our guides on how to increase your attack level and how to increase your defense level.
- Bring healing food. The fight is long enough that you’ll want it. See how to cook the best healing food.
- Know your combat options. If you’re not fully comfortable with the combat system, brush up on how to use Axiom Force and all sword mastery challenges to sharpen your skills.
- Don’t forget the spear variant. If you like this weapon’s style, there’s also an Electro-Mecha Spear found at Regent’s Rise in Gorthak Territory — no boss fight needed. It has 30 Attack Damage and deals lightning damage on each of its first five hits, resetting every 5 seconds.
Crimson Desert has no shortage of tough fights tied to great rewards. The Machina Knight is one of the more satisfying ones once you understand both phases. Learn the rhythm in Phase 1, switch fully to dodging in Phase 2, and the Electro-Mecha Longsword is yours.
