I have modified wrestling skill in accord with my play tester's feedback to read as follows:

"The ability to wrestle someone into a 'Pinned' position, thus subduing them. It is not designed to do damage. The Effect Roll determines the Difficulty Level for the Opponent when they try to escape from a pin. Holding someone in a 'Pinned' position successfully (ie they fail their escape roll) indicates that they've been successfully subdued."

Thoughts and/or suggestions are welcome.
