Awesome? Not really. If you look closely... You have -30% all resistances on mobs from single staff, but you have also -10% mag res from ring (as i remember). Look again on Corvus's stats page. He have +30% pen for all, but he should have +40% mag pen and rest +30% pen
This set is rly not usefull... I thought it reduces resistances, not add resistances. So it's a +30 pen... When I'am using it all monsters on Torment got +30 resi so I can't kill any monster becouse they got 100+ resi all... Who made this strange set...
So it doesn't work correctly cuz when I'm using item which Reduces monster resists Magic stats says Damage from xxxx reduced 40%. At this set is -40 so monsters are getting 40% less dmg from any element
Positive value of your penetrations means negative values of monsters resistances. So when you have +40% magic penetration mobs are getting -40% to their magic resistance.
I have a trade proposition. Does anyone, willing to upload, have Rathma's Wisdom (the helmet)? For that I can trade you the other 3 items in that set, for I have them all.
