Naturalist's potion

The Naturalist's potion is a one dose potion only available in the Dungeoneering skill. Using the potion boosts Cooking, Farming, Herblore and Runecrafting by 4 + 4% of levels. This is necessary for some doors which require a Farming, Herblore or Runecrafting level above the player's maximum. The boost for levels 1-24 is 4, for levels 25-49 it is 5, for 50-74 it is 6 and from 75 upwards it is 7.

It is made by adding Wormwood leaf and Misshapen claw to a Vial of water. This requires level 63 Herblore and grants 139.5 experience when made. This potion can only be made in dungeons with complexity level ≥5.
