As with any good RPG, Slayers 2's weapon refinement system enables players to push their gear past its original power. Refining these weapons requires materials, so you need to know what to farm and save up. Here’s how to farm ores and make use of the weapon refinement system in Slayers 2.
How to Unlock Weapon Refinement in Slayers 2
To unlock the weapon refinement system, you first need to be at least level 60. Once you reach the required level, travel to the Hidden Mist Village and find the Refiner Hagane NPC inside the big blacksmith tower. Finish his quest to unlock access to the refinement system.

Finding the village is the tricky part. Follow this route:
- Spawn at the Hidden Mist Village Shrine and just go straight onto the ramp in front of you.
- When you reach the middle of the road after the ramp, jump down into the fog on the right side.
- After you land, look for a tall pagoda building.
- You’ll find Hagane inside.

Best Ways to Farm Refinement Ores in Slayers 2
After you unlock the refinement system in Slayers 2, to be able to use it, you need to have some required materials in hand. These are the items you need to have in your inventory while refining your weapons:
- Refinement Ores
- Mythic Refinement Ores
- Wen

Wen comes easily. The ores are the materials that you need to know how to farm, so let's look at how to get them.
Method 1: Defeating Bosses (Best Method)
Fighting bosses is the best way to farm ores. You get ores from their loot, and they can also drop Mythic Accessories. You can take those accessories to Ginzo NPC in Mistfall Harbor and trade them for Mythic Refinement Ores.
In short, every boss kill gives you two chances at ore. No other method comes close. Here is where to find each boss:
- Zuko - Right outside Windy Peak.
- Saneri - North of Windy Peak
- Shinora - Inside Mistfall Harbor
- Giyen - Southwest Bamboo Grove Sanctuary
- Rengu - Forgotten Ruins, south of Mistfall Harbor
- Obari - Northeast Bamboo Grove
- Zentaro - East of Obari
- Tengai - Iceveil Settlement, north of Windy Peak
Method 2: Opening Chests
You can also get Refinement Ore or Mythic Refinement Ore by opening chests. However, they have different drop chances. Here is the list of drop chances and the chest sources:
- Sealed Cache Tier 3 - 4%
- World Events Chest - 4%
- Sealed Cache Tier 2 - 2%
- Snow Chest - 1.4%
- Sealed Cache Tier 1 - 1%
- Lost Chest - 0.6%
Method 3: Fishing
Another way to get ores is to do some fishing. The drop rate is very low, so it is not efficient. Still, if boss fights feel too hard right now, grab a rod, sit by the water, and hope you get some.

How to Avoid Weapon Refinement Failure in Slayers 2
Basically, the weapon refinement system in Slayers 2 is an RNG system. If the refinement is successful, your weapon gets upgraded. But if it fails, it gets downgraded instead. So, if you are having bad luck but keep pushing it, you will burn through your materials quickly.

The fix is the Refinement Guard. It prevents the level from decreasing when a refinement fails. You can get it from boss drops or by fishing, but it will be extremely rare. So if you get it, save it for weapons that are already high level.

The weapon refinement system in Slayers 2 is a double-edged system because it relies on RNG. You might upgrade your weapon if you succeed, but you also risk lowering its power if you fail. It’s best to try it out on lower-level weapons first to get a feel for the chance system. Either way, it’s best to farm ores early, so you have them in stock whenever you want to refine your weapons.
