Resist Magicka magic effect
http://www.uesp.net/wiki/Morrowind:Resist_Magicka
Magic resistance is applied when a harmful effect of a spell, potion or item is initially added to a character, thus making it possible to get temporary magic resistance, then equipping an item with a harmful permanent effect, and not worry about it.
