Bring 10 Rotting Wood and 4 Bloodvenom Essence to Impsy in Felwood.
Now that I have my felcloth, I can really begin making *my* pet.
It's going to need some eyes though. Perhaps you could rip some rotting wood from the irontree folk for me, so I can carve out some lovely eyes. They're up north in the Irontree Woods.
I'll also need some bloodvenom essence to give it that new demon smell. The tainted oozes carry the essence, and they hang out right here near Niby and me.
