Is attacking for 0 magic an option? Shadow squirrel and muffins would benefit a lot from this if they can.
Also, if you're attacked from an ability as opposed to the "attack action" do your when attacked things trigger? Ie: tag gets hit by rugged, does he keep his face down magic? Or if blixem sneezes on the table that has a Gretchen fuzzy mage, does she get to counter attack? If she does does she get to immediately or does blixem get to activate it's just allergies first?
