Herbert pet detail

The Herbert pet is an item that can be found while training Herblore. It can be used to unlock the Herbert pet.

It is unlocked by training Herblore via making potions, cleaning herbs, or burning herbs. Gaining this pet is based on the amount of experience awarded at once; the more experience granted per item made, the greater the chance of gaining this pet. The chance is not affected by experience boosters. When a player obtains the pet, they receive one of the following messages:

While skilling, you find Herbert, the Herblore pet. It has been added to your inventory.

While skilling, you find Herbert, the Herblore pet. However, you do not have enough inventory space, so it has been sent to your bank.

In a purely mathematical format your chance f of receiving the pet on any particular action is

f = \frac{B \times S}{2,250,000,000}


  • B is the base experience per action
  • S is the virtual skill level. At 200 million experience, a flat bonus of 200 is applied to this value
