Locks are the ancient form of peace enforcing. Even the most toughest bullies calm down rather quickly when they are targeted by a painful joint lock. Of course, this technique requires much concentration and devoted training, to be effective. And by training the art of locks, one also improves the skill to resist them. The would-be enforcer needs a free hand or similar appendage for any real chance of success.

Usage: use 'joint lock' [target] use 'joint lock' release
