Analysis, Discussion and Tips for Success
General Discussion
When the Hunter skill was added to RuneScape, among the new creatures that came with it were swamp lizards, orange salamanders, red salamanders and black salamanders. When caught, these are actually used as weapons, consuming “fuel” that is made from a combination of swamp tar and various herbs. The ability to make these herb tars was added to the Herblore skill, providing a nice alternative to players looking to make something other than potions.
Herb tars are made by combining swamp tar -- not swamp paste -- with one of four herbs: guam, marrentill, tarromin or harralander. Each results in a particular “flavor” of tar that is used as fuel by one of the four lizards/salamanders. It can also be used as bait to trap them.
When first introduced, herb tars were an appealing option for many herblorists, since it had a "Make-X" option from the start, meaning it required far fewer clicks than making potions. Even now that most of Herblore has "Make-X", tars are still simpler because they are a one-step process. And depending on market prices, it can be an economical training vehicle as well, especially for harralander tar, which is in moderate demand.
Location and Access
You can make herb tars at any bank, but a one-click bank like Castle Wars is preferred.
Required and Recommended Equipment
You need a mortar and pestle.
Required and Recommended Supplies
You need just the input items shown.
Familiar Suggestions
Summon a foraging familiar to earn extra money for you while you work -- I prefer the magpie, given the high value of rings and gems today. There isn't a really worthwhile forager below Summoning level 47, so I wouldn't bother with a familiar at lower levels.
Technique and Tips
At any bank, take out a mortar and pestle and a big stack of swamp tar. Now withdraw a full inventory of clean guams. Click the tar and then one of the guams; when the message appears in the game's text box, right-click and choose "Make All". Wait about a minute, bank the guam tar and repeat. That's it! Each load takes only about a minute.
