Wild Area Event #1: Butterfree, Drednaw & Corviknight .

This is the first wild area event held by Sword and Shield. Despite publicizing that Gigantamax variants for Butterfree, Drednaw and Corviknight were to be more easily available, this event also allowed encounters for the Gigantamax variants for Sandaconda and Centiskorch.

Drednaw and Sandaconda were Sword exclusive raids, and Corviknight and Centiskorch were Shield exclusive raids.
Though it is important to note, host can include players of the opposite version to join in the raids.

This event ran globally from November 15th to December 4th, 2020.
