I think we might use an example of how the tick system works. I just wrote one anyway in a PM, talking about Kaiser.<br/>Tick 9:  Kaiser attacked 3 times and made a HGD perfect parry.<strong>Until your next action,</strong>1) he had a -3 on his DV, and 2) he can use no other charm! Kaiser's next action is on tick 14.<br/>Tick 13, he was attacked. Kaiser used HGD, because it's before tick 14.<br/>Tick 14, he activated PBA. It only gives you a penalty of 1, but until tick 19, Kaiser cannot use a perfect parry! He better hope the DB doesn't remain up after his strike, or he's not going to like what happens on tick 18... ;)
