Tal Raj set question

[double]

Hi there, I have complete set for my sorc except for ammy,I see the MF on armor alone is 88% then i see the complete set is only 66%?Does the mf stack 88+66 or do you lose some MF with entire set?

They get added together.
You get 88% from the armor, plus the 66% set bonus.

you can also socket the armor with ist or perfect topaz to get even more mf...
