Final Location: Phantom Forest (after poison log)
Pre-Reqs: Pet Pal Talent to finish the quest, might be possible to get achievement without.
Directly north of the Phantom Forest - Thorny Grounds way point you should find the kickstarter tree (large hollowed out tree with rune engraving all over it), in original edition it displayed a list of all backers.
Take a StarDust herb and drop it on the ground while standing in front of this tree and the WereSheep should come out and unlock the achievement.
I am not sure if any of the quest steps are needed to actually get the weresheep to come out but I will include them just in case.
- Find the book The Legend Of The Weresheep in a burial mound in the large graveyard located by the undead church in Cyseal.
- Read the note The Last Weresheep located in the treasure room in Hiberheim
- Talk to the ghost of the Weresheep located in Mardino's cave (Luculla Forest), dig burial mound
- Read note Weresheep Recipe, found in the same location (if I remember correctly)
- Find weresheep by Kickstarter Tree.
