this is a really good source of any spell,unit or item statistics that you might be interested in. It shows you which spells can be negated by magic resistance(if there is a "MR negates" in the spell's description) and if it doesnt say that then it is not negated by MR, but probably something else (like fire damage with fire resistance).
