I have noticed that in dom2 patch 2.15 the spells like charm, disintegrate, drain life ... are really much more effective than before that patch (that is good because SC are in someway more vulnerable).
Is something in the way MR negates spells changed ? I have seen my sauromancers with 4D and a spell focus (so -3 in MR modify) killing enemies with high MR (15 and more) almost without any missing ... far away from what I was hoping by the statistics.
