Wind Spring
Wind Springs are used to power a variety of tools. They have to be wound up in the Coil Winder before they are able to apply charge to items.
Handbook Description[]
The wind spring is used to store mechanical energy. Once wound up with the coil winder, it can be used in another winder to provide a small amount of power, or it can be used to run various tools. Note that when charging coils, they run the risk of breaking, a risk which gets larger and larger as they are wound tighter and tighter.
