Guard Roll
From NsdWiki
When an attack successfully lands, the attacker rolls for Damage and the defender attempts to Guard.
+ | END | + | Guard | + | Armor bonus |
The difference between the Damage Roll and the Guard Roll (if positive) is the amount of Health Points lost.
If the defending character has Magic Defense and the weapon being used to attack is magical, the magic bonus the attacker receives is subtracted from the defender's MDEF. If the defender has more Magic Defense than the attack has bonus points, the bonus doesn't apply, but the bonus to the attack is never negative.
