Herb sack

A herb sack is an item that can be bought from Slayer masters for 750 Slayer reward points. Buying it requires level 58 in Herblore (CANNOT be boosted) and allows the player to store up to 30 of each of the grimy herbs listed below, for a total of 420 grimy herbs. Players cannot store cleaned herbs in the herb sack. Attempting to do so will result in the message You can't possibly put that in there, it would spoil your sack.

The herb sack can be checked to find out how many different herbs it contains. By clicking it all herbs in inventory will be deposited in the herb sack unless it is full.

The herb sack is useful for killing monsters that often drop valuable herbs, such as Flesh crawlers, aberrant spectres, and deviant spectres, since it only takes up one inventory slot.

Any herbs placed in the Herb sack will disappear upon death to an NPC! For this reason, it is advised that the player not lose focus when killing dangerous monsters like Deviant Spectres, or their whole trip's herbs could be lost.
