Guam tar

Guam tar is a tier 30 members item worn in the ammunition slot for Ranged, with a high alchemy value of 1 coins. No shop sells Guam tar and no monster drops it, so an Ironman makes it: it takes 19 Herblore and gives 30 Herblore XP, using Clean guam and 15 × Swamp tar. There is one other recipe below.

“A thick, foul-smelling, tar-like substance with a green tinge.”

Ironman verdict

Where the materials come from: Clean guam (made with 1 Herblore); Swamp tar (sold by Lletya General Store). Making ten takes 10 × Clean guam and 150 × Swamp tar and gives 300 Herblore XP. Reaching level 19 Herblore takes 3,973 XP in total; the Herblore calculator counts the actions and materials to any target, and the Herblore guide has the Ironman training route. One recipe uses Guam tar: Green salamander. It is worn in the ammunition slot at tier 30 as ranged gear; compare it with every other piece on the Ammunition list. Guam tar is members-only. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 1 coins.
