[b]Additional question[/b]: Two of us have the Atronach starsign. It provides a fifty percent spell absorption passive, meaning half of the spells you're hit with turn into raw magicka rather than inflicting damage. How is that to be handled? 

Skyrim does a full absorption on every 1 of 2 spells, but half absorption on all spells may be more reasonable given the medium we're using for play. I just want to be certain come time to be struck with whatever magic is likely to be slung at us at various points.
