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.
Grimy torstol can be harvested from torstol plants grown in a herb patch. A fully grown torstol will yield a minimum of three grimy torstol at harvest. When picked, each grimy torstol gives 224.5 Farming experience.
Harvest yields for torstol plants are determined by a "harvest lives" system. Each torstol plant begins with 3 lives. Additional lives are added with the use of compost (+1 life), supercompost (+2 lives) and ultracompost (+3 lives). Every harvest action will roll a chance out of 255 on the specific patch's "Chance to Save", taking one of the harvest lives from the patch if it does not hit; the patch will be cleared when it runs out of lives. The "Chance to Save" is dependent on the player's Farming level.
