I did not see yet such protection shield spells. Maybe the system is different, I did not play the first game.
Now you are safe from any cc as long as you have enough physical or magical armor (except the extremely annoying slow effect of oil which ignores magical armor, why? why? why?). There are also several skills which buffer you from the effects of surfaces, the problem is there are a lot other skills necessary for combat.
The problem is not the stun from magical abilities cast by you or foes. For me the problem is the long lasting surface effects, three turns a row.
Which sometimes occurs out of the blue. Today I had it two times that blood was electrified in a fight although nobody, neither me nor the enemy, applied an electrifying skill at all. It is kind of crazy.
