I was running a playtest of my DFRPG scenario I'm going to run, and a player asked a very good question.
His wizard was attacked by a Red Court Vampire. He replied that he was throwing up a shield.
In looking at the rules, I couldn't see anything that allowed him to use magic as a reaction. (I couldn't find anything that ruled it out explicitly, either...)
So, my question is this... if someone is attacking a wizard, can he use a spell for the opposed roll? Seems to me that an answer either way would greatly effect the way the game plays.
I also had a stealth question... I was running a playtest on Thursday, and someone wanted to move and use his stealth at the same time. I know Stealth talks about modifiers due to movement, and the Speed Powers can chop 2, 4, or more off modifiers due to movement... but I couldn't find any mention of how movement modifies the difficulty... best I could find was movement modifying the difficulty of any roll (p 312), but that only gave a +2... so the Superhuman and Mythic Speed abilities seem like overkill.
Not having time to look up anything at the table, I just said, "OK, +1 difficulty for each zone you move through," and that worked for the moment, but I'd like to know what the actual rule is.
