Default Partial parry

I'm curious how to model a cinematic thing I've seen a number of times: using a sword to deflect the brunt of a magical attack or a large projectile, reducing the damage to a manageable level.

This came to mind as I was re-watching Avatar: The Last Airbender. We frequently see someone attacked by a power (earthbending attack throwing a rock, most commonly) and parrying with a sword. The sword deflects the brunt of the damage, but the target is still hurt some.

Am I missing a rule that would cover this? Parrying seems to be pretty binary in GURPS. I've considered a houserule based on Power Parries from Supers, but can't come up with anything satisfactory.

Maybe a DR power triggered by a parry roll instead of automatic/skill roll?

My completely unplaytested suggestion would be something like this:

Deflecting Defense: This is an option for any Active Defense. You accept you are going to get hit, but interpose your weapon or maneuver your body to limit the damage. You get a +2 on your Active Defense, but even on success, you are still hit and take 1/2 normal damage. If you fail the Defense, you take the hit normally and if you attempted a Parry or Block, the attacker may choose to hit your weapon or shield hand instead of where they targeted the attack.
Shield Brace: This is an option for Blocking with a shield against a slam. You accept you are going to get hit, but set your shield to ensure it takes the slam instead of you. You get a +4 on your Block, but even on a success, your shield is hit by the slam for full damage. You may not combine a Shield Brace with a Deflecting Defense.

I think they're reasonably balanced: you get a minor bonus, but you're guaranteed to take the hit for at least some damage. If you're in a bad situation, or are well-armored compared to your foe's attacks, they can be lifesavers.

I like these! I think they work pretty well. One thing I might suggest is that on a critical success on the defense, damage is instead quartered instead of halved.

I've used a "graze" rule before. If someone just barely hits (i.e. has a MoS of 0 on the hit roll) or if a defender just barely defends (i.e. has a MoS of 0 on a defense roll), minimum damage is sustained.

I haven't used the rule in a while because I have wanted to keep things simpler lately. But when I was using it, the rules didn't break (though I had to make some calls on the fly for cases of fixed damage).

You can allow mundane attacks to power parry certain powers as part of mundane countermeasures.

That's exactly what it is, a Power Parry.

In this case it's something that requires the user have a Power, in this case Striker or Innate Attack bought as a sword.



However, you could also use the cinematic skill Parry Missile Weapons to cover this.

It looks pretty balanced, but doesn't quite fit. low-powered or low-damage attacks are completely negated by the parry. Having some damage break through is a sign that the enemy is powerful.

Do you have a page or book reference on that? I have access to lots of books, but don't have a good mental index for where to find what yet.

Perhaps. I was not thinking this would be something that should cost extra, but chi-powered DR with a roll required and perhaps a FP could be quite affordable.
