i would like to use the martial block skill as a parry with weapon ability in my fantasy campaign. this manuever gives +2ocv/+2dcv. is this a correct interpretation, i apply the +2ocv on my attempt to parry, then if i miss my attack (parry) roll, my opponent is now attacking me at a -2 due to my increased dcv. i've also given up my attack this segment. only against this opponent if our next action segments are at the same time will i have the chance to strike first.
