Swamp tar detail.png

Swamp tar can be found in Lumbridge Swamp and Mort Myre Swamp (just north of the swamp boat). They will be lying around on the ground.

After starting the Lunar Diplomacy quest, you can also take swamp tar from barrels in the Lady Zay. There are four barrels on the first level down in the ship and three on the second level. A barrel contains one to twenty swamp tars. However, 2 pieces seems most common and anything above five is rare.

Swamp tar may be gained from Lletya General Store for free after completion of the easy set of Tirannwn Tasks, with a maximum of 30 in stock.

Cave slimes, aberrant spectres, warped tortoises, and warped terrorbirds drop swamp tar in reasonable amounts. Swamp tar can also be obtained as a reward from Big Chinchompa, as well as being generated in small amounts when smelting corrupted ore when the Voice of Seren is active in the Trahaearn District. Swamp tar can be a good money-making method for lower level players.

It cannot be bought from Charter Ship employees, however you may purchase swamp paste.

Making money

Swamp paste

When joined with flour and then heated on a fire or range, it becomes swamp paste, a sticky item used in the Shades of Mort'ton and Fishing Trawler minigames. It also plays a role in several quests. Note that swamp paste can be purchased far more cheaply from stores or the Grand Exchange.

Herb tar

Swamp tar, when combined with certain herbs, is used in the Ranged skill as ammunition when a salamander is wielded as a weapon. Swamp tar can be used with guam, marrentill, tarromin, or harralander to create the following ammunitions:

Lamp oil

Swamp tar can also be distilled into Lamp oil using either the still in the Rimmington Chemistry shop or the still at Miltog's lamp stall in the Dorgesh-Kaan marketplace. Note that a still will not load the Lamp oil into any container except an empty Oil lamp, Oil lantern, or Bullseye lantern.


Swamp tar is used in several quests.
