I had an idea for simulating active dodging in combat. It uses Ultimate combat variant rule of Armour as DR. Instead of vigor points as damage soak, it is used as stamina.
Upon the attacker declaring an attack, before the roll is made the defender chooses to dodge(example). You choose to add as much reflex save up to your maximum reflex save as dodge modifier in AC. You reduce that amount of reflex added into your vigor points.
For Parrying- Perhaps using CMA to make an attack check against the attacker's check. Like duelist's parry, taking into consideration size modifiers. Afterwords, reducing vigor points by an amount again.
This may seem like players seem to be missing all the time, but this is how combat works. Both parties parry, feint and testing each others' defences before finding a weakness and kills.
What you guys think?
