Ironman verdict
Marrentill tar is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 2 monsters and 1 recipe for it.
You can make it yourself with 31 Herblore from 15 × Swamp tar and Marrentill. Each one made gives 42.5 Herblore XP. The best rate is from Locust rider: 1/128, 80 at a time.
The material you can buy or make: Marrentill, made with 5 Herblore.
It is worn in the ammunition slot; its biggest bonus is +22 ranged strength.
No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 1 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 179 coins; only alch it to clear space.
