Unidentified Herb

Unidentified Herbs have always been in Classic and always will. If you have the required herblaw level to identify the herb, it will turn into a random herb, which you can then proceed to grind up with your pestle and mortar.

Once grinded, you can choose one of two things to use it for. You can sell it on the streets for mad profits, or you can get high. I reccomend the second, as it will level up your herblaw.

How to get
Killing Monsters is a great way to get these herbs.

You can buy from drugdealers, but only if you've got a good amount of cash on you.
