Hi, it is about the weapon ability "concussive", like in the dragit-crytsals as option. From what I read if you get hit with a weapon with this ability, you are unable to perform an action for the number of rounds of the concussion value. To put it straight, if I am hit with this modified lightsaber with "concussion 2" I can not attack the next two rounds. If we think that the other guy is not a complete idiot, he will hit me again until I am dead and I stay unable to perform actions until then...
Do I miss something? Is there a defence against that?
