How to play as Seraphine
If LeBlanc commits Distortion(W) toward you, aim Beat Drop(E) across her landing spot and the return point; a Seraphine player recommends lining E up with her W pad so it can catch her if she returns. (Unverified: no source confirms this note.)
Back off when LeBlanc moves into Sigil of Malice(Q) or Distortion(W) range, and save Surround Sound(W) plus its echo for her burst if she commits; Seraphine players recommend preparing the shield when LeBlanc threatens to jump in. (Unverified: no source confirms this note.)
After LeBlanc uses Distortion(W), she can recast within four seconds to return to her starting spot; Seraphine can aim Beat Drop(E) across either position.
