Yes. Item is one of the built-in positive expedition outcomes. Its default event weight is 14, which equals about 12.5% with the standard total weight of 112.
How does this expedition outcome work?
The event means an expedition can return an item instead of resources, ships or Dark Matter. The exact item result should be treated as part of the active world configuration rather than a universal guaranteed list.
What are the default parameters?
A weight of 14 does not mean a fixed 12.5% chance in every universe. If an administrator changes this or any other event weight, the effective percentage changes automatically.
What determines the result?
Treat items as an additional expedition bonus rather than an outcome that can be fully optimized through fleet composition. Sending a particular fleet does not guarantee an Item event.
How should you use this in practice?
Default event weights are only the built-in starting configuration. An administrator can change them, so the real frequency in your universe can differ from percentages calculated from the default total weight of 112.
What should you watch out for?
Do not treat a single expedition as a guaranteed return on investment. The outcome is random, and even a positive event can be limited by fleet parameters, bonuses or free cargo space.
