A new evolutionary and overland PokeStop item has made its way into Pokemon GO: The Rainy Lure.
PokeStop Lures and their occasional double-function as evolutionary hubs aren't a new feature in Niantic Labs' augmented reality (AR) mobile game. Trainers have seen this a couple of times before with the Glacial and Mossy Lure Modules meant to prompt Eevee's evolution into Glaceon and Leafeon, respectively. Specific type and circumstance Lures have also been pre-established with the Magnetic Lure Module meant to attract electric and steel-types.
Rainy Lure Pokemon GO Evolution Item
The Rainy Lure Module is almost translucent with a light blue-green—almost teal or bright turquoise—color with an equally schemed screen and accents. This is likely meant to invoke a watery image in connection to its function with viewers just barely able to make out the technological workings under its shell.
Trainers can find the Rainy Lure in the Shop tab along with the other available Lure types. As a special Lure, its price falls in with its Glacial, Mossy, and Magnetic siblings at 200 PokeCoins. It's for this reason that we assume it will function identically to them—as well as the fact Niantic hasn't given off any impression otherwise.
According to its description in the in-game Shop, it is "a wet Lure Module that attracts Pokemon for 30 minutes, especially ones that love the rain. It can also cause some Pokemon to evolve."
This may seem vague at first. However, as experienced trainers may have already guessed, it simply refers to Pokemon who appear more often in rainy weather conditions: bug, electric, and water-types.
It's currently unclear exactly which Pokemon will need the Rainy Lure to evolve and whether or not this has anything to do with Niantic's recent release announcement for Goomy, the "Soft Tissue" Pokemon. Our bet is that it will take on the role of "Water Stone" similar to the Glacial and Mossy Lures.
The Rainy Lure is available now from the Shop.
