Special Raid Event


 * Not to be confused with Special Raid Challenge.

Special Raid Event, includes Week or Weekend, is an irregular event that is hosted during a short period of time and features a returning Legendary Raid Boss which may have a chance to be shiny.

This event format may have been discontinued by Niantic as Raid Boss changes are less fixed format nowadays.
