Tarromin tar is an ammunition that can only be fired out of Red salamander. It can be made at level 39 Herblore and yields 55 Herblore XP by using clean tarromin with 15 swamp tars. A player must have a pestle and mortar in their inventory for the herb to be crushed into tar. It requires 60 Ranged to wield.
The data in this table is based on the Grand Exchange prices of the Herb and 15 Swamp tar. It is accurate assuming all items are bought off of the Grand Exchange and the result is sold afterwards.
