This is the value that determines your chance of getting a higher rank sword.
The higher the value, the better the chance, however you can get a high rank sword with little to no quality, and you can still get the lowest ranked sword with maxed quality. All it does is greatly influence what will happen, not determine it.
- Quality can be affected by.
- The highest hammer quality value.
- Cumulative Crafting Points.
- Mastery level for the material.
- Trophy Bonus.
Remember, higher quality, the better the chance at a higher rank sword, so especially on rare materials, you want to raise your quality to be as high as possible by taking advantage of everything you can.
