Their release marks the first time that Riot Games has dropped two champions on the same day since 2010, when Pantheon and Gragas came out.
Xayah is intended to be an AD carry, using her feathers to deal large amounts of damage and occasionally root people in place. Her partner Rakan is a support with strong initiation tools and a ton of mobility. Each has an ability that grows in strength when paired with the other, as well as a special recall that can be synced up to back simultaneously, even if one of them initiates theirs first.
Taylor Cocke plans on feeding on Rakan within the hour. Follow him on Twitter @taylorcocke.
