Question about magic resist

As a tank i’m planning on 4 pieces of cloth armor to get tankyness against magic, cause now i can rely on my shield to block physical. Got the gear ,and i read the mastery

So, havin 4 pieces, i get “magic defense increase”, i dont know what numbers, also 15% reduction.

But then i can LEVEL this into the swordsman guy, quite expensive, and in the wiki i read that it has 50 ranks. What do i get by levelling this passive? 3500 silver to enter rank 2, and takes half hour. It says nothing about what do u take, or maximum ranks
