EoD Strike mission rings cannot be attuned.

[ZeftheWicked.3076]

Talking at the very least Master Specter's Ring and Master Untamed's Ring.

Decided to be a bad@ss and earn my way into my ritualist specter by doing EoD strikes and clearning Harvest Temple strike.
Yet now when I want to take my specter into fractals it's a no go, because i can't attune these rings for extra infusion slot.
The mystic forge does not recognize the recipe (Agnonized Essence + agony infusion + Philosopher's Stone + ascended ring) and does nothing. While with other rings it works just fine.
