Your weapon in Blade and Soul will grow in power and ability alongside your own.
Regardless of the path you take, your weapon will be a consistent tool throughout your journey. From your earliest days of training in your chosen martial art, until your last, your weapon will be your constant throughout. Early in your journeys you’ll come across a weapon of immense power—a Hongmoon weapon—your weapon. This is the tool you will keep with you, and work to increase in blade and soul power along your journey.
When defeating your foes they will at times drop their own weapons or you will be rewarded with training crystals, and these can be sacrificed to imbue your weapon with their strength. As you add the power from other weapons to your own, it increases in level, enhancing the weapon’s power and attributes.
Once it has reached Stage 5, it can be coaxed to breakthrough to Stage 6 with the power of a specific rare weapon, and rare reagents.
Now your weapon can continue its journey to Stage 10 and transform into a new weapon once a different rare weapon and reagent have been collected. After the transformation has been completed, your weapon will return to Stage 1, but with a new appearance and name.
Difficult enemies keep the weapons needed to begin a breakthrough or transformation, and the rare reagents can generally be found through repeatable quests within certain areas of the world.
In addition to your weapon, your path will also include a selection of accessories that also increase in power in the same way as your weapon--fed with other accessories—and also breakthrough tiers using rare accessories and reagents.
Enemy weapons aren’t always destined for destruction though; they also provide unique appearances that can be kept and used to change the look of your own weapon. There are tales of very rare and powerful Legendary quality weapons that can sometimes even rival the power of your Hongmoon weapon at the highest levels of expertise.
The success of any martial artist will not only rely on their own physical strength and training, but also of their weapon.
