Shi Feng carefully held the two deep-red Dragon Source Crystals in his hand and inspected them again.
As legendary materials, Dragon Source Crystals also varied in quality.
Of course, these quality distinctions were not set by the system, but rather summarized by players through various experiments. They could be considered hidden system attributes. Though the conclusions still carried some margin of error, the discrepancy from reality was very small.
Different grades of legendary materials also provided different increases to an item's crafting success rate.
According to player classifications, legendary materials were generally divided into four grades: basic, intermediate, advanced, and top-tier.
Basic materials could increase the success rate by around 2% to 3%.
Intermediate materials could increase the success rate by around 4% to 5%.
Advanced materials could increase the success rate by around 7% to 8%.
Top-tier materials could increase the success rate by around 10% to 11%.
After Shi Feng opened the attribute panels for the two Dragon Source Crystals, he carefully read their descriptions.
"Great!" After reading the descriptions, the corners of Shi Feng's mouth rose slightly. "There shouldn't be any problem making Dragon Soul Potions now."
The criteria for judging different legendary materials varied slightly. For example, the description on a Dragon Source Crystal specified the concentration of the bloodline it contained.
Concentrations from 1% to 30% were considered basic grade, and these were commonly dropped by monsters.
A concentration of 31% to 50% was considered intermediate grade, but their drop rate was very low.
A concentration of 51% to 70% was considered advanced grade. They could not be found on the market at all and were treasures hoarded by major guilds.
Anything above 71% was top-tier material. Even a top-tier legendary material with no practical use was worth far more than an Epic item.
