Nami vs Seraphine

Cast Aqua Prison (Q) on a slowed or immobile target, or where they're heading: the bubble lands in an area and stuns every enemy on impact.

Cast Tidecaller's Blessing (E) on your ADC just before they trade: their next autos and abilities slow and deal bonus magic damage.

Cast Ebb and Flow (W) so it bounces from one champion to another: it heals each ally, damages each enemy, and only hits the same champion once.

Cast Tidal Wave (R) to engage or to break an enemy engage: enemies hit take a knock-up and a slow, which lasts longer on those farther away.

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.
