My current group is debating a new house rule and, being curious, I was wondering what people here had to say about it. The rule is this:
If a KA does no body to it's target, after defenses, then STUN damage remaining after defenses are applied is halved.
Example, Gun Boy shoots his pistol (a 2d6 RKA) at Mr. Brick. He hits his target and rolls 10 BODY with a STUN multiplier roll of 5 for a total of 40 STUN. Mr. Brick's rPD is 25. Since no BODY damage gets through, then the 15 STUN Mr. Brick normally would take after his PD is applied gets halved to 7.
Our campaign is 4-color superheroic. The idea is to better reflect the way super-tough charcaters like the Thing or Colossus seem unfazed as the bullets bounce off of them.
Our discussions have already touched on the fact that this penalizes PCs who use KAs, like our sword-wielding PC Musketeer. We've also discussed how a PC like my Hard Eight, a brick with 35rPD (20 hardened!), basically gets 50% resistant PD damage reduction for free.
One specific question I had was, if the rule gets adopted, should it apply regardless of attack power advantages like armor piercing or penetrating? I figured that BODY damage is BODY damage, and that if you take one point of penetrating BODY you don't get to halve the STUN, but another person thought that penetrating BODY damage should be exempt from the house rule.
Thoughts?
