Request: Key Item: Quadav Charm for Beadeaux (S)

To open a Corroded Gate in Beadeaux (S) at (I-10), you need the Quadav Charm.
This is just like Lower Delkfutt's Tower and the Delkfutt Key.

And like the Delkfutt Key, I believe it would be good to make your first trade of a Quadav Charm to turn that item into a Key Item version of itself.
