Herblaw

Herblaw is one of the most popular members skill. The ability to make potions without the help of a NPC. This guild will teach you the basics and what you can do with the proper herblaw level. Before you can use herblaw you will need to do complete the Druidic Ritual Quest. Go to the Quest Guides for more information on that.
Potions

A herb is a green fern-like plant that you can obtain by several different means. When you do find a herb, it will most probably be unidentified. The first step would be to identify it if your Herblaw skill allows you to. Just click on the herb to attempt to identify it. Herbs are useless if you haven't identified them. Here's a lift of herbs you'll need to identify.

The ground ingredients come from the name of the item, just grounded. In order to ground Unicorn Horns and Bluedragon Scales, use the pestle and mortar bought from the herblaw shop.
Weapon Poison

Weapon Poisoning can only be done on Throwing Darts, Daggers and Arrows. The Poison effect will also not effect monsters, only players.

When a player is poisoned, the effects will either wear off (if it hasn't already killed you) or can be cured with the Cure Poison Potion or Poison Antidote. The Antidote will also stop poison effects from coming back temporarily. Cure Poison Potion however, does not do this.
