Grimy torstol detail

A grimy torstol is a herb that has not yet been cleaned to make a clean torstol. Grimy torstols may be grown from a torstol seed with a farming level of 85, which is dropped by certain NPCs. Cleaning a grimy torstol requires a Herblore level of 75 and gives 15 herblore experience. Clean torstols are used to make Overload potions with a herblore level of 96 or Zamorak brews with a Herblore level of 78. Grimy torstol is one of the five herbs that cannot be obtained from the Sorceress's Garden.

One grimy torstol plus 8 other grimy herbs can be obtained from the closed chest in the Yanille Agility dungeon when unlocked with a Sinister key.

Grimy torstols are also possible loot from using a Columbarium key on a wooden alcove acquired by cremating a Vyre corpse in the Paterdomus Columbarium, or as the high herb reward from the minigame Temple Trekking.

Cleaning grimy torstol yields a profit/loss of 159 coins coins per herb.
