Herblore

Herblore (Herblaw on ) is a skill that allows players to make their own potions. Before players are able to begin using it, they must first complete the quest. This gives enough Herblore to raise the skill to level 3, which is the first level at which players can make potions. Players that have not completed the quest may utilise the to borrow someone else's Herblore level and make potions, though they will not receive the experience for doing so.

Herblore appears to have been established by in Past A, as revealed after finishing the  quest and then talking to her.

Although it is easy to get Herblore to, it is one of the most expensive skills in the game for players who buy all or most of the needed ingredients. For players who gather the ingredients (most are available from monster drops and some spawn in various locations), it is much less expensive but quite time consuming. The current minimum requirement to be ranked (at approximately rank 928,098) on the for Herblore is level 30.
