NieR Automata: Weapons' level 4 upgrade - how to achieve? NieR Automata guide, tips
Last update: 04 August 2021
This guide page for NieR Automata explains how to advance weapons to the maximum fourth level (Level 4). You will find instructions on where to find the secret blacksmith and information about the requirements for reaching level 4.
Weapons' levels 1-3
As you progress through the game, you can receive and find new weapons. Each of them is at the first level (Lv. 1). Level up your favorite weapons to increase their statistics (e.g. more damage) and grant them new features (e.g. improve attack speed).
Upgrading weapons can only be done by a trader. The first trader is Weapons Trader staying in the Resistance Camp (options for interacting with him will become available after completing several initial quests in that location).
After talking to the trader, select the Upgrades option. You will see a list of the weapons you currently possess along with the requirements for upgrading them. You must:
- spend a certain amount of gold,
- use specific crafting materials- their list is displayed on the right side and you can get them, e.g. as loot or as rewards for completing quests.
By default, you can develop weapons to the third level. After reaching Lv. 3, a dash will appear to indicate that further upgrades are not available at this merchant. You can get a hint about looking for a unique blacksmith who could further improve the weapon. Finding him will be your next task.
Level 4 - how to get?
The earliest when you can develop your weapons to level 4 is in Chapter 6, specifically during the exploration of the castle (the one where the camera is located on the side).
When exploring the castle, you must reach the Access Point from the above image.
Go back to the right and jump down to the lower shelf. In the place marked on the image, you will see a large crate you can push. Move it to the right (you will also be able to use it to return to the top).
Examine the passage on the left that was obscured by the crate. You will enter the hideout of Forest Blacksmith Masamune.
Masamune can upgrade weapons to level 4 - you have to pay him and provide (rare) crafting materials.
Upgrading any weapon to the fourth level will be rewarded with Tools of the Trade bronze trophy.
