Evasion Roll

Any impending attack allows for either a Dodge or a Parry at the player's option (unless your character is somehow unable to move). If the attacker's Attack Roll is greater than the defender's Dodge/Parry Roll, the attack hits and damage is calculated.

Dodge

A character who is quick on his or her feet can try to remove their person from the path of an opponent's attack. This is done with a normal Dodge skill check.

A character who may not be fleet of foot but is adept with a weapon can attempt to parry an attack out of the way.

The defending character may use any accuracy-related bonuses. Some weapons grant a bonus when used to parry, and some actually present a penalty.
