I thought sundered meant it removed the immunity all together
Immunity and resistance are different
Immunity means the monster has 100 or more resistance
To remove immunity, you need to make the monster go to 99 or less resistance. Given infinity only does -17 resistance against immune monsters, if a monster has 117 or more resistance, they remain immune.
- enemy resistance from things like facets only work against monsters that aren’t immune, or to be more clear, monsters that have 99 or less resistance. Therefore, if you are fighting a monster that has 117
Or more resistance, facets won’t lower the resist below 100, making them still immune.
Sunder charms automatically set your enemy’s resistance at 95, making them no longer immune. Then infinity lowers their resistance by 17 since they were previously immune. Making the enemy now gave 78 resistance. Then your facets will lower their resistance further.
