Someone do this math for me.

So i'm Evelynn

I have my W with 35% MR Reduction.

I build Void Staff, Morellonomicon, Sudden Impact and Sorc Shoes.

If my opponent has 100 MR, 50 MR and 150 MR how low will their magic resistance be?

Flat MP: 41 Percentage Penetration: 75%

The practice Dummy is only losing 35 of it's MR so i'm curious.
