Swamp tar can be found in Lumbridge Swamp and Mort Myre Swamp. It can also be collected from barrels on the Lady Zay, located one floor below Captain Bentley. The player must start Lunar Diplomacy to have access to these barrels.


Lamp Oil

The lamp oil used for fuel in Lanterns is obtained by distilling swamp tar in the chemist's house in Rimmington or at the lamp stall in Dorgesh-Kaan.

Swamp paste

It can be combined with flour and then heated on a fire to become swamp paste, a sticky item used in the Sea Slug quest as well as the Shades of Mort'ton and Fishing Trawler minigames.

Herb tar

When combined with a Guam, marrentill, tarromin or harralander, swamp tar becomes a tar used in the Hunter skill as bait ingredient while catching salamanders. This paste also doubles as ammunition for the salamanders when used as a weapon. 1 herb is needed for every 15 swamp tar.

The action of creating the herb tar can be used to manipulate game ticks, allowing you to do certain actions faster.


Swamp tar is involved with several quests.
