How to Upgrade Weapons and Specs in Reign Piece Guide
Upgrading your weapons and specs is an important part of getting stronger in Reign Piece. A good weapon or spec can already make a difference, but improving it further can help you deal with stronger enemies, bosses, and harder content more easily. Reign Piece has a large selection of weapons and combat specs, so knowing where to upgrade them can save you a lot of time.
The main place you need to visit for this system is the Blacksmith in the Royal Palace. You will also need Embers and other materials depending on the upgrade you want to perform. Here is everything you need to know about the weapon and spec upgrade system.
Where to Find the Blacksmith in Reign Piece
The first thing you need to do is find the Blacksmith NPC. The Blacksmith can be found inside the Royal Palace, so make your way there before starting your upgrades. The Blacksmith is not only useful for one type of equipment. This NPC is connected to the system that allows you to improve both weapons and specs. Because of that, it is worth remembering the location, especially if you are regularly farming bosses or other content for materials.
Before going to the Blacksmith, make sure you have the weapon or spec you actually want to invest in. This is important because you do not want to spend your upgrade materials on equipment that you plan to replace shortly afterward.
How to Upgrade Weapons

Once you reach the Blacksmith, interact with the NPC and check the available upgrade options. Select the weapon you want to improve and look at the materials required for the next upgrade. The upgrade system uses Embers as one of its main resources. Different types of Embers are available, and you need to obtain the appropriate materials before you can continue improving your equipment. A simple upgrade process is:
- Travel to the Royal Palace.
- Find the Blacksmith NPC.
- Interact with the Blacksmith.
- Select your weapon.
- Check the required Embers and materials.
- Collect anything you are missing.
- Return to the Blacksmith.
- Perform the upgrade.
- Repeat the process when you have enough materials.
Do not spend every material immediately if you are still testing different weapons. It is usually better to decide which weapon fits your build before investing heavily in upgrades.
How to Upgrade Specs
Specs can also be upgraded through the Blacksmith system. Specs are important because they determine many of your combat abilities, so improving a strong spec can make a noticeable difference during PvE and boss fights.
The process is similar to upgrading a weapon. Go to the Blacksmith, select the spec you want to improve, and check which Embers or other resources are required.
If you already have a spec that you use regularly, upgrading it can be more useful than spreading your materials across several different specs. This is especially helpful when you are preparing for difficult bosses where stronger abilities can make farming much faster.
What Are Embers Used For?
Embers are important materials used for upgrading weapons and specs. You should start collecting them as you play because you will need them once you begin investing in your equipment.
The game has different Ember types, so do not assume that every Ember can be used for every upgrade. Check the Blacksmith menu to see exactly what your selected weapon or spec requires.
The best approach is to identify the upgrade you want first and then farm the specific materials needed for it. This prevents you from wasting time collecting random resources that may not be useful for your current build.
How to Farm Upgrade Materials
The best way to prepare for upgrades is to combine material farming with your normal progression. Instead of stopping everything to farm materials for hours, work toward your upgrade while completing quests, fighting bosses, and exploring different areas.
Bosses are particularly useful targets when they drop materials that you need. You can also take advantage of areas where enemies spawn quickly, especially if your character can defeat them without much difficulty.
For example, if you are working toward a Kokushibo-related build, you can continue farming the required bosses and demons while also building up your character’s overall strength. This makes your grinding session more productive.
Upgrade Your Main Weapon First
If you have limited resources, avoid upgrading every weapon you own at the same time. Pick the weapon you use most often and focus your materials on it first.
A strong main weapon can make farming easier, which then allows you to collect materials for future upgrades faster. Once your primary weapon is in a good position, you can start working on secondary equipment.
Your choice should also depend on your preferred playstyle. If you like fast attacks, prioritize a weapon that fits that style. If you prefer heavy damage, focus your resources on a weapon with stronger attacks.
Upgrade Your Best Spec
The same strategy applies to specs. Reign Piece has multiple specs, and it can be tempting to upgrade everything as soon as you unlock it.
However, spreading your materials too thin can slow your overall progression. Choose the spec you use most and focus on making it stronger first.
A powerful spec can help you clear enemies faster, defeat bosses more consistently, and farm additional materials. Once your main spec is strong enough, you can begin investing in other specs for different situations.
Don’t Waste Rare Materials
One of the biggest mistakes you can make is spending rare upgrade materials without planning ahead. Some materials can take time to farm, so think about your long-term build before using them.
If you recently unlocked a weapon but are not sure whether you will keep using it, test it first. Check its moves, damage, range, and how well it works with your current spec.
The same applies to specs. Try the moveset before investing a large amount of Embers into it. Once you know that the spec fits your playstyle, upgrading it becomes a safer investment.
Upgrade Before Farming Difficult Bosses
If you are struggling against a boss, check your weapon and spec upgrades before simply trying the fight over and over again. A stronger weapon can improve your damage output, while an upgraded spec can make your abilities more effective. This can reduce the amount of time needed for each boss fight.
Upgrading your equipment is especially useful when you are farming a boss repeatedly. Even a small improvement can become valuable when you repeat the same fight dozens of times.
Is Upgrading Weapons and Specs Worth It?
Yes, especially if you plan to spend a lot of time farming bosses and higher-level content. Reign Piece is built around collecting different weapons, specs, and other combat options, so improving the equipment you actually use is an important part of progression.
The Blacksmith system gives you another way to increase your character’s power instead of relying only on finding new equipment. This becomes particularly useful once you already have a weapon or spec that you enjoy using.
The important thing is to upgrade with a plan. Focus on your main build first instead of spending every Ember as soon as you receive it.
The weapon and spec upgrade system in Reign Piece is fairly straightforward once you know where to go. Head to the Royal Palace, find the Blacksmith, select your equipment, and check the materials needed for the next upgrade.
Embers are the key materials you should pay attention to, so keep farming them while completing bosses, quests, and other activities. For new players, the best strategy is to choose one main weapon and one main spec before investing heavily in upgrades.
Once your primary build becomes stronger, farming bosses and collecting materials becomes easier. From there, you can gradually upgrade additional weapons and specs and build different setups for the content you want to play.
