Each character has a strike chance % based on (mostly) their manual dexterity and the base chance of the weapon used to attack. Additional factors, such as running into an attack or achieving surprise—as in an ambush—modify this base chance. The defender's defensive % is subtracted from this number, and percentile dice rolled to see if a hit is achieved. When a hit is delivered, the attacker rolls a d10, adds the weapon's attack bonus, and subtracts the target's armor rating. In some cases, such as a target with plate armor, few weapons can do much damage directly. Only certain special hits can damage the target severely. But with time, even the most heavily armored Knight can usually be worn-down.
