Cornifer Notes & Tips
- It is completely unknown how he discovers new areas and gets to them. For example, there are only two known ways to get to Howling Cliffs. The access from Greenpath is to narrow for him, and the access from King's Pass requires parkour that would be impossible for him. And yet, he's there. In addition, in Fog Canyon, he is literally past a Void Stream, which is impossible to cross without the Shade Cloak.
- If ever you miss Cornifer in the area, you won't be able to find him there the second time around, but he'll leave a note saying that you can purchase the map at a higher price by visiting Iselda's (his wife) shop.
