Unnatural Characteristic

One or more of the creature’s characteristics is unnaturally enhanced.
This is indicated by a number that is then added directly to the relevant Characteristic bonus. For example, a creature with a Strength of 41 normally has a Strength bonus of 4. If the creature had Unnatural Strength (3) then its Strength bonus increases to 7 (4+3).
A creature can have this trait more than once, but each time must be applied to a new characteristic.
Successful tests using a characteristic tied to this trait gain a number of bonus degrees of success equal to half the Unnatural Characteristic value.
