The City of Lives
Characters can also take unspecified devices as stunts. This is useful for characters who are likely to carry around a variety of devices and need to pull out just the right thing for the occasion. These sorts of devices are called universal devices.
When a character begins an adventure, his device doesn’t need to be defined. Instead, at the point where they decide they need it, they reveal the device, which can have two improvements. If a character has multiple stunts, they can combine them to make one device with many improvements. Once the character has declared the device, they have it for the rest of the adventure.
If the character wishes to introduce something a little more dramatic, they may instead introduce a wonderful toy.
