3.5.4.1. A Shield Bash is defined as using a Shield to strike an opponent from a distance further than two steps away.
3.5.4.2. A Shield Check is defined as using a Shield to strike an opponent starting from a distance less than two steps away.
3.5.4.3. A person may not Bash, Check or Shield Kick an opponent’s rear quadrant. Shield pushing or incidental contact in an opponent’s rear quadrant is allowed.
3.5.4.4. Shield Kicking of small Shields and/or Bucklers is discouraged.
3.5.4.5. The head may not be the intentional target of any shield maneuver.
I would like to propose the following addition:
3.5.4.6. A person may not Bash an opponent with a disabled leg.
I've received and delivered some crappy shield bashes with legged opponents. Shields to faces are the biggest problem (Now disallowed), but being knocked clean over, hitting heads on the ground, being stepped on or other incidental body contact are all problems.
I feel that the potential for injury is significantly higher in comparison to doing the same to a non-legged opponent - An opponent without a disabled leg can easily dodge or move to reduce the impact of the bash, as well as being in a better position to stabilise themselves or catch themselves before hitting the ground. A legged opponent has very little they can do in terms of evading the shield bash or stabilising themselves after contact.
A shield check can often achieve the same result in combat as the shield bash, while presenting significantly less danger to the legged opponent.
(Note: At this time this is not yet a motion, just a thread to promote further discussion)
