"Devil's Snare", one of the rare Grade 4 Herbs, could be used to make Potions with normal attributes. Its market price was much higher than the value of other Herbs the likes of the Grade 5 Earth Essence. It was also as valuable as a set of fairly good Tier 4 Violet Equipment. Naturally, many other players besides Qin Ruo would also drool over it and want to get their hands on it!
There were many players who were unwilling to put themselves in front of danger on the battlefield. So they quietly turned their attention towards the Devil's Snare and a few other Potion materials around it.
Nonetheless, it would, of course, be better to possess a higher-level of Gathering to collect that sort of high-grade Potion material. That way, the quality of the gathered Potion materials would be better preserved.
