“Errata” Iconic Thermal Katana Weapon Guide – Cyberpunk 2077
Cyberpunk 2077 “Errata” Iconic Thermal Katana Weapon Guide

The cyberpunk 2.0 patch has added a new iconic Katana, called “Errata”. It has a special effect that allows it to deal thermal damage, and deal guaranteed critical hits against burning enemies. In addition, it allows you to leap towards enemies. This guide will go over how to get and properly use this weapon.

Quick tips before you head off to get the weapon:

  • It is easiest to acquire during the “Disasterpiece” quest. While the weapon can be obtained at any point after this quest too, it’s by far the easiest to acquire during this quest, as you won’t have to pass a Technical Ability attribute check of 20.
  • Reflexes build recommended. While powerful, the weapon is nowhere near as powerful as it can be with the perks located in the Reflexes perk tree.

Acquisition

To acquire this weapon, you must either start or finish the “Disasterpiece” main quest, which is a part of the Evelyn Parker questline during Act II.

This quest will take you to the Electric Corporation Power Plant, which is where this weapon is located.

If you have a Technical Ability attribute of 20, you can also break back into the facility. If you do this, there will be no enemies around, unlike during the Disasterpiece quest, where the plant is filled with Scavs.

In either case, make your way to the Electric Corporation power plant, located here on the map:

After you arrive, you’ll need to get inside. There are several ways of doing so.

You can go through the main gate, open a locked side door, or climb up a half-destroyed adjacent building.

Once inside the compound, head into the facility through the main entrance.

Follow the path inside to the right, where you’ll find an open gate.

On the other side, you’ll see an illuminated staircase leading down, with “SECTOR 0” written above it in white paint. Go there.

Continue following the hall downstairs until you spot a set of windows, and jump through.

Turn to the right and go through a door made of metal bars.

Follow the stairs down until you reach a door with a red light above it, and go through.

You’ll enter a rectangular room. There will be a double metal door on the left side of the room. If you are getting this weapon after doing the Disasterpiece quest, you’ll have to unlock it with a Technical Ability check of 20. If you are getting this weapon during the quest, the door will be open.

Go through the door, turn right, and then go through the hole in the wall on your right. You’ll see a large furnace inside through the hole.

Usage 

Unlike most other katanas, using Errata will allow you to be far more mobile than usual, almost like combining the strengths of both Thermal Mantis Blades and the Katana.

  • Holding and then releasing the attack button while moving forward and aiming at an enemy will make you leap toward the enemy. This leap isn’t as strong as the Mantis Blade leap from the Relic perk tree, but still allows you to cover a distance of about 10 meters or so.
  • This weapon has a 30% chance to apply a burn effect to your enemy. While this isn’t the most powerful effect imaginable, it is still quite powerful.
    • The weapon will always deal critical damage if you hit a burning enemy. Incendiary Grenades are virtually guaranteed to cause a burning effect, so using them with this weapon is highly recommended.
  • Being fast and aggressive is a necessity with this weapon. Pairing it with a Sandevistan will make dodging enemy fire a lot easier.

Build Tips

  • Other than the obvious perks in the Blades branch of the Reflexes perk tree, the Movement branch also has several perks that pair magnificently with this weapon. Such as:
  • Mad Dash. Doubles your dash distance while dashing towards an enemy. This perk pairs amazingly with the leaping ability of this weapon. Combined with the Air Dash perk later on in the tree, you can achieve Jailbreak Mantis Blades-level leaps with this weapon.
  • Aerial Acrobat. This perk allows you to easily control your character while in mid-air, making the Errata leaps more controllable (and more deadly)
  • Another consideration with this build should be how you set enemies aflame. There are 2 main ways you can do this. A spreading Ovearheat quickhack, or the Incendiary Grenades.
    • If you are planning on using the Incendiary grenades, pick up the “Pyromania”, “Demolitions Surplus”, “Heat Shield”, and “Friendlier Fire” perks from the Grenades branch of the Technical Ability perk tree.
    • If you are planning on using the Quickhack route, pick up the “Copy Paste”, “Overlock”, and “Spillover” perks from the Intelligence perk tree.
  • The “Microrotors” circulatory system implant will increase your attack speed with this weapon, which makes it an obvious choice, especially since it only removes 12 cyberware capacity points.
