How to find it
The Pleasing Garden, much like the Maze of Death is not seen on the map, rather you have to wander the desert near Ships Graveyard until the camera starts to zoom in.
The Pleasing Garden is a maze of illusions, going through the wrong door can set you back quite a bit, so check carefully and heed the townsfolk's warnings.
You'll find Jack's Grappling Hook tool here.
Stare Roe and the Light Rune are a nice price to nab here.
