Random idea about EoN

What if the item didn't gave MR? I mean, the item is made for assassins, right? Assassins should be squishy but be situationally really strong. The shield screams Assassin. It has a preparation time so it can't be used if caught out or in the middle of a battle and the spell blocking is impactful enough to decide wheter you live or die. It's just perfect for assassins.

Then we get to the MR. It makes no sense at all to have that. If an Assassin is caught out, he shouldn't be able to tank the damage. Assassins should be extremely squishy. If the MR were to be removed, it would make things a bit less frustrating to enemy mages, while still allowing the item to have it's niche.

The cost, of course, would have to be adapted or some other stat would have to be added.
