Herb Running

Herb running is a way to make money on runescape. This is done by killing Chaos Druids (Edgville dungeon commonly used)and picking up the herbs they drop. Then they sell them at the grand exchange for

Players also have the option of picking up the runes they drop too, and also the Mithril bolts they drop. The commonly targeted herb using this method is the Ranarr, which costs (sells) for about 12k in the grand exchange.

Location
There are three location these monsters are located. 1. The Edgville dungeon 2. The Taverly dungeon 3. The Yanille Agility dungeon

Strategy
Some of these spots can be extremely crowded at peak times on most worlds. Bringing a fast weapon will help a lot. When you go there do not bring any food unless you're very low leveled because it will take up inventory space. However, it is advised to bring one way of teleportation (worn or inventory) because revenants do come through the Edgville dungeon sometimes. You'll see about 1 every 4 or 5 times.

What to pick up
Only pick up herbs, mithril bolts, and law runes. The only herbs you should pick up are the ranarr, lantadyme, avantoe, irit, kwuarm, dwarf weed, and cadantine. However should you come upon a rare drop (dragon spear, rune crossbow) PICK IT UP!

Revenant attacks
If you don't bring a teleport tab when going to the edgville dungeon and a revenant attacks you, DON'T ATTACK IT! Run to the gate and open it and step out. Wait until the revenant hits the gate (it will disappear) and go back to killing chaos druids.
