Kasumi sprang forward to attack, her power making her move much more rapidly for a few moments.  Reaching the undead caster before it could finish it's spell, she struck with both feet impacting it's chest, then kicking out again, a trifle off balance.<br/><br/>((Two natural twenties, followed by a 17 to strike.  Confirmation rolls of 18 and 22.  As I don't know the creature's AC, I include all the damage rolls. 12, 12, 10, 10, 7))
