Carsomyr does not
add Magic Resistance - it
sets.
Like you noticed, you can un-equip / re-equip to get your Magic Resistance to the ceiling -
but - and this is the where the 'sets' part comes in - the next time your mighty Paladin (or cheesy Thief [img]tongue.gif[/img] ) will swing the Holy Avenger in the air (aka, next blow), the Magic Resistance
resets back to the original 50%. Jim tested and proved it a while ago.
So, no skyrocketing Magic Resistance with Carso.
