Well this might have been posted before but i thought of giving out my idea about this topic
the game has a few pieces of gear with out normal damage resistance. like the divine set and the dragon scale set ans also the Radiant silvermail Set . Without the normal damage these users will take more damage than others with this damage resistance. so in my opinion there should be another way to cover up this gap. Hence we could use a trinket of varying normal damage resistance. like one of 4* and the other 5*
As far as i know there were some such trinkets but where for some reason removed from the game?

pretty much, Monsters cause split damage normal/their specialty. as long as you have one defense, normal defense is obsolete
