How to play as Lucian
Use Relentless Pursuit(E) to sidestep Beat Drop(E) or High Note(Q), then take a short Lightslinger(P) trade while Seraphine's spells are on cooldown.
Lightslinger(P) empowers Lucian's next two attacks when an enemy champion is immobilized, so Seraphine's Encore(R) can set up extra damage once Lucian can attack again.
Relentless Pursuit(E) gives Lucian a dash he can use to dodge Seraphine's long skillshots and look for a quick countertrade.
How to play as Seraphine
Track Lucian's dash before committing Beat Drop(E); he can use Relentless Pursuit(E) to evade the line and punish its cooldown.
