AFAIK - against immunities conviction work with part of his strenght (25%) but I am not sure that I remember correctly. This mean that monsred res will redused with 21%. For example against 130% resist to fire monster this aura will reduce monster res to 109% - still remain FINeoSyrex said:It will be enough to break a lot of immunities. Level 12 Conviction is -85% resist all. Only a 200% resistant monster wouldn't be broken by it if you equip your merc with a +2 all skill helm and armor since that would reduce all resistances by 105% (assuming the runeword doesn't have a ranging level for Conviction).
Keep in mind (according to Arreat Summit):
-most immune monsters range from 100~170% resistance
-XXX-enchanted mod gives 75% resistance to an element to the monster, 50% to minions
-magic resistant mod gives 40% resist all (not sure if this includes minions, probably does)
-spectral hit gives 20% fire, ice, and lightning resistance to the boss only
So there will be some monsters that can stay immune, especially when combined with a beneficial boss bonus, but it will still be enough to break tons of immune monsters. And don't forget that breaking resistances isn't the only benefit conviction gives. For non-cold sorcs it will hugely increase your damage (up to 22x if the monster had 95% resisance) without even having to equip any -res items.
Keep in mind this runeword, along with many other runewords hasn't been completely verified. So don't start building new sorcs yet. :xsmile4:
Anyway - coviction is great aura because also reduced monster defence rating and increase chance to hitting monster.
@melianor - is this runewords will work for SP?
