Exploration Stage: Angel Statue
From: Huntress
Description: Assembly is simple and such a cannon is easy to put together. While you go looking for one of the main components, the magnetic coil, get to work. Look near the angel statue. The guide may not have taken all the parts from over there yet.
Completed: While you were away somewhere I finished my work. The blueprints were too old and I had to correct a few things. It said to use maidenhair.
