The Star Magnet is a passive item found in Momodora III.
When equipped it works like a money magnet, dragging munnies to your position and automatically collecting them.
The Star Magnet can be very useful in combination with the Golden Flower, dragging huge sums your way and even getting the money that would normally be out of reach, for example if it dropped into a spike pit.
A Star Magnet can be purchased from the Bunny Shop Girl in Old Madryn for 100 munnies.
