By the way, regarding this toy, there’s a bug in rarity, it doesn’t count attempts in LFR/normal/heroic and only counts them in mythic for some reason, even though the toy drops everywhere. I ended up getting it in heroic

According to wowhead, the item also drops from the LFR/normal/heroic chest: Gift of the Nightborne
Unfortunately this means more SPECIAL code has to be added, because Rarity doesn't support multiple sources for the same item. The comments also suggest the item can be bonus-rolled. I have no idea how that works in interaction with the chest.
