Usage
The Battery Pack's sole use is as a crafting component for building contraptions in the Workshop.
Spoilers Within
This section contains spoilers for all Battery Pack contraptions.
The Battery Pack is required to assemble three different contraptions:
- Battery Pack + Broken Lever + Sledge Hammer = Power Hammer
- Battery Pack + Broken Lever + Shovel = Jack Hammer
- Battery Pack + Compass = Powered Electromagnet
None of these contraptions prevent the Battery Pack from being obtained again on subsequent days if they are carried through by the Moon Pendant or stored in Coat Check, allowing it to be used in multiple contraptions at once.
Beyond the Estate
This section contains datamined information about another effect. It may contain spoilers for various stages of the game.
When the Battery Pack is obtained, the Dynamic Rarity of the Workshop is randomly set to Standard or Unusual (50% odds). Collecting another Battery Pack in the same day will choose the one not selected last time.
