The Fall of Brekhan
Parrying Blade Damage
The blade of any weapon is delicate, and in an ideal world any block done with a blade (Sword, end of a nagatana, rapier, ect) should be done with the flat of the blade, not the edge. In combat, however, it isn’t always possible to line up a parry correctly and the edge takes the brunt of the damage. When both weapons are edged, it comes down to quality and luck to determine who takes the worst of the damage.
Any solid weapon (Sword, Mace, ect) has a default HT of 12, weapons with simple moving parts HT 11 (Flail, whip) and anything more complicated HT 10. Cheap weapons are at a -2 to HT, fine weapons at a +1, and very fine weapons at a +2. Weapons that are extremely well taken care of (At least an hour a day, always stored properly, and shielded from the elements at all times) are at an additional +1. If two bladed weapons collide, the blade made of the superior metal is at +2.
When a parry with a blade is succeeded by a margin of 0, the edge of the parrying blade is hit instead of the flat side. First, determine the damage the attacker would do if he had hit the weapon on purpose (B483 for basic rules, B557 for HP and DR). Now each weapon rolls modified HT. If the attacker wins, the parrying blade takes this damage, representing a blunted edge, chipped section, or bent metal. If the defender wins, and is also attacking with the edge of a weapon they take damage to their blade. If the defender is not attacking with the edge of a weapon, they take no damage. In the event of a tie, both weapons take damage.
If a weapon is disabled by the damage, see B485 to determine what remains of it.
Note that it is not possible to choose to hit a weapon like this, or to defend like this on purpose. For that, use Attacking a Weapon, B400.
