Malfunction Rating

Each mechanical object has a Malfunction Rating between O and 5. This number represents the chance that the item will suffer a catastrophic failure when used. If you roll a number equal to or below the Malfunction Rating (MR) when making a skill check or attack roll while using the device, the object fails to operate correctly.

Any device with MR 1 or higher requires a skill check or attack roll to use. The skill is usually Knowledge (Engineering), with a DC depending on the task (Technology Score – 10 is a good default if no DC is listed). The GM may allow alternate skills for a simple device that does not require the user to understand the details of its operation. A motorized plow might be best used with a Profession (farmer) check, while most weapons use ranged or melee attack rolls as appropriate.

All devices list any special circumstances if a malfunction occurs. Most items simply stop working until repaired, either with magic or an applicable set of checks (DC as determined by the GM, typically similar to the ). Dangerous items such as Black Kernel weapons often destroy themselves in ways that threaten the users and those near the item – not to mention making repairs more than a little challenging.
