Some artifact mods are enhanced by having armor with the "Eido's Apprentice" mods. I have tried farming some seasonal armor, but how do you expect us to use armor that has not rolled more than a 59 for me? I have used tonics, and I have tried everything; I believe drops for seasonal armor rolls have to be bugged because there is no way we are expected to use these hilariously rolled armor pieces.

Nearly all of my Armor is from quite literally 8 seasons ago or more. My Shard count was insane though....
