Weapon Fusion Guide

This is a guide to upgrading weapons by Fuse Weapons in Hyrule Warriors: Age of Calamity (HW:AoC) for the Nintendo Switch. Learn how to unlock the Blacksmith and upgrade weapons through Weapon Fusion, and how to transfer skills to other weapons.

How to Unlock the Blacksmith

Clear the Road to the Ancient Lab

Weapon Fusion can be done at the Hylian Blacksmith Guild. Before the Blacksmith even appears in the map, you'll have to clear the second battle of Chapter 1, Road to the Ancient Lab. Finishing this battle will unlock the Blacksmith and a few more quests and challenges.

The Brawny Blacksmiths will appear northeast of the Hyrule Field. Assist the blacksmiths by giving them 5 Ironshrooms. Supplying the required materials will give you access to the Hylian Blacksmith Guild's services, such as weapon fusion and selling weapons.

How to Fuse Weapons

Weapon Fusion Steps

Select a Character
Select the Weapon to Upgrade
Select your fusing materials (weapons you will give up to fuse)

The steps above show the basic process for fusing weapons. Note that once you give up a weapon for fusing, you cannot get it back!

Notes about Weapon Fusion

CheckmarkLevel up weapons with a high base attack

CheckmarkA bonus is obtained when fusing weapons with the same seal (Skill: +1% | ATK: +5)

CheckmarkA new skill slot is unlocked for every five times a weapon levels up

When using the Blacksmith, it's important to keep the things listed here in mind. Since fusing weapons of the same seal will give you an attack and skill bonus, it's a good idea to continuously fuse them as you gain them.

How to Transfer Weapon Skills

Steps for Transfering Over Skills

Select the weapon you will upgrade
Select a weapon with a skill you want to transfer over
Finish selecting fusing materials

Fuse Weapons With the Same Seal!

CheckmarkDecide on which weapon you'll upgrade

CheckmarkGather 4 weapons with the same seal

CheckmarkLevel up to Level 19 using fusing materials with no seal

CheckmarkUse fusing materials with the same seal to reach level 20

Buy fusing weapons that have the same seal, you'll be able to obtain a skill and attack bonus. Although you can use other weapons with other seals to gain skills, fusing weapons of the same seal allows you gain powerful bonuses to make the most of your weapons. Therefore, it's better to only use weapons of the same seal when fusing and leveling up!

Grinding for Weapons

You're going to need a lot of weapons to reach level 20. The easiest thing to do is to change your difficulty to Easy mode, then try to repeatedly clear battles in the quickest time possible.

Weapon Fusion Tips

Farm More Weapons

Upgrading weapons is only possible by weapon fusion, and weapons will also be used as materials in the process. Obtain more weapons from battles, such as Challenges, to upgrade the weapon of your choice further.

Another easy method of gaining weapons comes from scanning amiibos, which can allow you to gain materials and weapons.

Transferring Weapon Skills

If your weapon has a free weapon skill slot, you can transfer a weapon skill from a component weapon through fusing. When transferring weapon skills, keep an eye out for matching seals as they can boost the weapon skill bonus and weapon damage even further, as mentioned above!

Be careful when choosing a component weapon with two or more weapon skills as only the first weapon skill will be transferred to the chosen weapon while the rest will be discarded.
