the latter is actually a non-issue however, as even if you are a Master of Magick[sup]tm[/sup] your magic could fail you, a slight distraction could halt your cast, they could reach you before your cast goes off. there are any number of reasons as to why the other /could/ feasibly win, and i actually find it more beneficial when I lose a roll, as I can explore those options. and whilst the probability of someone with 5 rolling that many 1's and someone with 1 rolling a 6, so is the probability that they would pull it off, if that makes sense?
