For the record, we have now confirmed that Nanika is a Dark Continent being (volume 33, image between chapters 341-342 "From the Dark Continent" written beside a picture of Nanika) and that Alluka at no point in the series was using nen. Her nen type should be considered unknown as a result.

The speculation that Nanika would be a specialist based on her powers "not fitting any other nen type" is just that, speculation. You could argue that her wish-granting is a manipulation of probability - it's very improbable that a blimp carrying millions of dollars would suddenly leak all its cargo over a forest, it's very improbable that Gon would ever just randomly recover. But who's to say with Nanika's amount of power that a nen ability that could do that very thing (manipulating probability) wouldn't be possible? You could construct an argument for a lot of different nen types for Nanika, but none of them are confirmed.

Unless there's a textual statement of a character being a specific nen type, something that can have a source attached to it, it should not be listed on the wiki to be taken as fact. Alluka might be a specialist, but she's never said to be one in canon. Nanika might be a specialist, but she's never stated to be one in canon.

The information we have is not enough to state either of them as having a confirmed nen type.
