Well, the reduction has to be 68%. There are two different methods used for reducing the damage. The 20% from Transparent armor is just a normal magic resistance. The 60% from Granitic Defense however is based on a damage event. Whenever a unit with the Granitic Defense buff receives damage, 12% * (Level of Granatic Defense) * (taken damage) is added the the life of the unit. Note that Granitic Defense reduces every kind of damage, not just spell damage.
