Got this from Reddit, credit to IM_Rami.
500 grey matter and the 8 leg pieces are needed for the Dr Spider MD pet.
- Spoiler:
1 On the musician at the intersection
2 Behind the catapult near the western crater
3 On the western most tent northwest of the musician
4 West of Doric's shop on a cart
5 Directly east of the entrance on the cart
6 On the cannon southeast of the previous leg
7 On the catapult in between the two craters closest to the stairs
8 West of the entrance on top of a barrel
Tip: Make sure you've got your 500 grey matter before you get your spider legs as the legs aren't bankable so will have to sit in your inventory until you have enough grey matter.
