House Rules
Combat
Cutting Damage Severing Limbs
If a cutting weapon does more than half the allowed damage to the limb, it is severed.
Example: If I have a HT of 12, and my hand can take HT/3 damage (4), then 9 points of cutting damage to the hand will sever it. My arm, which can take HT/2 or 6 points, will be severed if it takes 13 points of cutting damage.
Parrying Huge Foes
It's harder to parry a humongous foe. :) Still working on this -- apparently it's handled in 4th edition gurps.
Character Points, Training
Weapon Master advantage acquisition
If you already have a weapon skill of 16, you can begin putting character points in the 20-point Weapon Master advantage (CI-32).
