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.

Plus gatekeeping the Class Armor piece doesn't help either. Like seriously Bungie? Gave up on this season's armor, but still passively farming Failsafe armor which can drop at 68. Just keep the Hunters Journel artifact in your inventory. Engrams drop doing various challenges.
