Page "DragonQuest" Paragraph 9

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.
