Parrying is a Combat Skill that gives you a chance to block an attack.
While Weapon Combat Skills determine a players chance to hit a target, the Parrying Skill gives the player been hit a second 'check' to determine whether or not you receive a hit.
A player with GM Swordsmanship swings a halberd at a player with GM Fencing and GM Parrying wielding a kryss and a buckler. Since both players have GM weapon skills there is a 50 % chance the halberd will hit its target. After this first check is made, a second check is made that determines whether or not the hit is blocked, and as shown by the table below, there is another 50% chance of the halberd hitting his target. Thus, at GM level (weapon skill and parry) there is at most a 25% chance of hitting a player with parrying.

FORMULA: % Chance of Blocking= Parrying Skill / 2

The resulting damage received is determined by the type of Armor equipped.
