Farming[edit | edit source]

Grimy marrentill can be harvested from marrentill plants grown in a herb patch. A fully grown marrentill will yield a minimum of three grimy marrentill at harvest. When picked, each grimy marrentill gives 15 Farming experience.

Harvest yields for marrentill plants are determined by a "harvest lives" system. Each marrentill 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.
