The item database entry for the witchdoctor mask explains how to receive the mask, however the "Additional Rewards" section of the Herblore Habitat guide doesn't explain the method on how to receive the mask it just describes how to get witchdoctor items and get an extra mask.

Yeah, it would be nice if the guide mentioned that you need to catch the God Jadinkos in order to get the mask.

 

Went around catching all non-god Jadinkos thinking I could get the mask. :unsure:

Thanks for bringing this to our attention. I've made the addition to the guide to clarify just exactly how players can obtain the mask. Thanks for the explanation, Serp!

 

Any other questions or concerns, you can either PM me or post a new topic and we'll take care of it :)
