The sunder takes an enemy who used to be immune to the element and sets their resistance at 95%.
Your conviction (paladin or merc/demon aura) will work at 20% effectiveness from there. So level 15 conviction on a paladin that cuts enemy resistance by 100% will work as 20% on these previously immune monsters, and take that resistance to 75%.
-enemy resistance to the element works at 100% effectiveness, so if you have a -10% enemy resistance roll on your sunder, and -10% from your uber ancients jewel, the enemy's resistance would be at 55% now.
Example: You are a blood boil warlock that uses a merc with infinity like me, with a flickering flame helm (-15%), defender fire jewel in your off hand (-10%), and consumes a tainted (additional -15%).
A fire immune monster is sundered to 95%.
Level 12 conviction (normally -85%) lowers that resistance by 17% (20% effectiveness), bringing him to 78% resistance.
The -40% combined from my gear brings that down to 38% resistance.
The effect of this is that, on an immune monster when you have merc infinity, -resistance gear has a huge impact. It has little or no impact on monsters who aren't immune, as the conviction works with 100% effectiveness there so further -res doesn't mean anything. My -40% enemy fire resist really is ~+100% damage against these immunes (but +0% damage against non immunes for the most part).
