Mel vs Seraphine

Stay back and poke with Radiant Volley (Q): its projectiles explode in an area up to 950 range, and each hit applies Overwhelm.

Land an auto after each spell: Searing Brilliance (passive) adds three projectiles to it per spell cast, and enough Overwhelm executes the target.

Save Rebuttal (W) for a dangerous projectile: the barrier sends it back to its caster, and you gain a shield and move speed.

Hit your target head-on with Solar Snare (E): only the core of the orb roots, the aura around it just slows and damages.

Cast Golden Eclipse (R) to finish from range: it hits every enemy marked by Overwhelm, wherever they are, harder with each stack.

Dodge Beat Drop (E), especially if you're already slowed: it roots a slowed target and stuns an immobilized one.

Count her basic spells and back off before the third: Stage Presence (passive) casts it twice, whether it damages, slows or shields.

Spread out from your allies against Encore (R): each champion hit extends its range, and a charmed ally near you lets it reach you.

If you can engage, target Seraphine: her kit has no dash to escape.
