173 Rare Skill: Sneak Attack

Crystallized Spit of the Desert Rock Lizard (250G)

Grade: Perfect

First, Feng Luo confirmed the light-yellow, diamond-shaped crystal, and luckily, it was the objective of his mission this time. Moreover, it was a lot more than the 100g requested by Lin; the grade even reached the "Perfect" grade.

The materials, core crystals, and other consumable items had a system evaluation just like equipment. The only thing was that the evaluation standard was slightly different from that of gear. For materials, core crystals, etc., the system's evaluation was categorized into four categories—namely, Defect, Normal, Excellent, and Perfect.

However, there was one similarity: For the same items with different grades, those having the Perfect grade were much more expensive than the Normal and Excellent-grade items.
