User blog comment:Bluefox87/What are some good examples of specialization water divination?/@comment-25814498-20160529232023

Neferpitou's leaf wilted when exposed to her Nen, but other than that I can't think of any other examples. We've only seen water divination a few times in the show; when Gon, Killua and Zushi first learn Nen and on a few other occasions such as with the Chimera ants. Because of this, Neferpitou has been the only observable case of specialization detected through Water divination.

That being said, you don't need any examples from the show; anything other than the signs of the other Nen types(e.g., increasing the waters volume, changing its taste, etc) is specialization. Think of literally ANYTHING other than those 5 and it's specialization. Water evaporates; specialization. Leaf turns to stone; specialization. Water turns into a delectable beef gravy whilst the leaf transforms into a meaty stockcube; specialization.
