I'm just sitting here generally speculating about what trinket in my current arsenal have the best synergy per bossfight, and I found my good old Mirror of Broken Images and was wondering what role resistances have nowadays? Could it be worth a shot if I am, for example, tanking the flaming or the venomous head on Magaera? Or any other high magic damage fight like High Priestess Mar'li from the Council of Elders?
