The Witchdoctor camouflage gear is a random reward set obtained from the Herblore Habitat activity. Players can receive either the Witchdoctor robes or Witchdoctor legs by catching all ten normal jadinkos in the same week, then speaking to Papa Mambo. Since the reward is random, it might take a player several weeks or months before they are awarded the legs and/or robes. Players can obtain the Witchdoctor mask by catching all 3 god Jadinkos within the same week, then speaking to Papa Mambo.
Obtaining the entire set requires level 81 hunter, 77 Farming, and 54 Herblore (all of which can be boosted) to be able to attract and catch each type of Jadinko. Additionally, it is highly recommended (though not required) to have level 80 Construction (which can be assisted), since it's fairly costly to ask for Mambo to construct habitats for you.
Once you have caught all three god jadinkos in a given week, Papa Mambo will provide you with a 30 minute boost to Hunter, Herblore and Farming experience for wearing each piece of the witchdoctor camouflage gear while training these skills within the habitat. The witchdoctor mask and witchdoctor robes both provide a 2% xp boost, and the witchdoctor legs provide a 1% xp boost for a total boost of 5%.
Additionally, drinking a dose of a Zamorak's favour, Guthix's gift, or Saradomin's blessing potion will further increase the total bonus experience to a maximum 15.5% for Hunter, Herblore, or Farming respectively (since the 10% boost is applied after calculating in Mambo's bonus).
The complete set can be stored in the armour case of a player's costume room.
You may gain multiple masks by dropping your mask(s) before talking to Papa Mambo after catching all God Jadinkos.
