Harralander tar

Harralander tar can be made at level 44 Herblore and yields 72.5 experience points per herb. It is made by using crushed harralander with 15 swamp tars. A player must have a pestle and mortar in their inventory for the herb to be crushed into tar.

These are used when hunting Black Salamanders for net trap bait. It is also used as ammo for Black Salamanders.

Black salamanders are useful at the Barrows, since the magic attack of salamanders is not affected by the player's magic attack bonus. However, the salamander itself provides no magic bonus, and is two-handed.
