Calculating Damage

Weapon Damage Types and Damage Bonuses
Weapons do three basic types of damage: impaling, cutting, and crushing.

Total Damage
Calculated by taking the Thrusting or Swinging damage (depending on the weapon) and then adding (or subtracting) the weapon damage.
This total damage is all one type (Cutting, Impaling or Crushing).

Example: Axe (Cutting) SW+2

Thrusting and Swinging
Two ways to attack with a melee weapon: Thrusting and Swinging (Swinging does more damage).

Knockback
Crushing and Cutting damage can both cause Knockback, with Cutting only doing so if it fails to go through DR.

Every multiple of the target's STR-2 (before subtracting DR) of damage causes 1 yard of knockback.
Eg. 9 damage to a STR 10 enemy causes 1 yard of knockback.

Anyone knocked back must roll against the highest of DEX, Acrobatics, or Judo. Each yard knocked back after the first adds a -1 penalty. On a failure they fall down.

Armor Divisors
This is the number that shows how effective an attack is at going through armor.
These are always found in brackets after the number of dice and modifier.

Armor Divisor DR Modifier
(2) /2
(0.5) x2
(0.2) x4
(0.1) x10

Flexible Armor and Blunt Trauma
When flexible armor stops the damage from going through, but still gets hit with a significant force.
For every 10 points of damage (or 5 points of Crushing damage) the target suffers 1 HP of injury due to blunt trauma.
Layering other armor over top makes a layer that must be gotten through first.

Corrosion
An attack that inflicts corrosion damage destroys 1 point of DR per 5 points of damage after dealing damage.

Wounding Method Modifier
Small Piercing (pi-) x0.5
Crushing, Piercing (pi) x1
Cutting, Large Piercing (pi+) x1.5
Impaling, Huge Piercing (pi++) x2
