The book says Blocking is an Action, pg 133 of the core book, but says that you can use the chosen defense as a reaction, so does that mean that your Initiative has to come up before you can Block or are you just sacrificing your Page to Block. Also how does this affect the Defensive Extra because in the book, pg 138 the example makes Speed Demon's use of the Defensive Extra look like a straight up Reaction as it's even listen under Reactions. I really need some help untangling this, thanks in advance.
