Pokemon GOhas been treating players to a series of seasonally appropriate arrivals sinceDeerling and Sawsbuck’s introduction in September, and now that Halloween is on the horizon things have started taking a turn for the spooky. Costumed Gengar and Sableye have been introduced to the game alongside several other ghostly bonuses and events, some of which have yet to take place.

Alolan Marowak Raid Day is one such event. The special day was originally announced in a Niantic post detailing Halloween happenings inPokemonGO, but aside from a time and date, the event has remained relatively unexplained until today.

Niantic’s official support account has shared twoimportant Alolan Marowak Raid Day detailsvia Twitter:

Using these free Raid Passes alone, Trainers have the opportunity tochallenge eight different Alolan Marowak this Halloween, which should provide a fair shot at encountering a Shiny. Although Shiny appearance rates won’t be boosted on Alolan Marowak Raid Day, Alolan Marowak itself features a boosted rate because of its status as a Raid-only Pokemon. While not all Pokemon available from Raids alone feature a boosted Shiny rate, a large portion of them do.

Alolan Marowak is aregional Pokemon variant, like Galarian Ponytaor Alolan Raichu. This means that it’s a distinct version of an existing Pokemon species, in this case from Kanto. These regional variants often feature changes to the original species, like different typing and movesets. Marowak sheds its Ground typing and becomes a Ghost/Fire-type under tropical Alolan conditions.

Players can’t transform Pokemon into their Alolan forms by travel; these are “evolutions” in the real-world sense of the word. An Alolan Marowak must be captured as an Alolan Marowak, or evolve from Cubone who originate in Alola.

Given thatPokemon GOis tied to the actual map of Earth, rather than the Pokemon universe, players are unable to travel to Alola. Instead, Niantic gives players a chance to encounter and capture Alolan Marowak in challenging four-star Raid Battles. Players are also always able to encounter the Shiny form of this Alolan variant at an increased rate.

Independent researchers The Silph Road have confirmed Shiny Alolan Marowak to have an approximately 1-in-60 encounter rate. TheusualPokemon GOShiny encounterrate is nearly 1-in-300, so players will find Shiny Alolan Marowak relatively frequently when compared to other, more common Pokemon.

Pokemon GOis available now on the App Store and Google Play.
