It seems like the Grimoire still isn't counting completions that are part of a strike playlist, so I'm not sure how many times I've done the strikes (case in point: I have the Arc Flayer cape, but I don't have the Dust Palace grimoire card...) I got the Darkblade helm from the Exotic Sword version of the strike a couple days ago; I'd done sunless cell at least 9 times prior to that. I got the Arc flayer cape during a Heroic Dust Palace strike; I've probably only done the dust palace maybe 5 times total. I have none of the other strike-specific items. Edit: wait, I have the Burnt Marshmallow shader from wherever the hell that comes from.
