DOOHICKEY: You have a treasure trove of strange, almost nonsensical devices that somehow work extremely well. If you encounter any problem that may require a tool, such as opening a locked door or moving something extremely heavy, you can declare that you pull out a doohickey for the job; if you can describe a strange and roundabout way that this device works and everyone at the table agrees it’s sufficiently strange, you accomplish the task as well as if you had a regular tool.
