Nami vs Renata Glasc

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.

Stay behind your minions: Handshake (Q) roots the first enemy hit, then can throw them into their allies.

Step up when Handshake (Q) misses you: it's her only root, with a 16-second cooldown at every rank.

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

Spread out from your allies when she casts Hostile Takeover (R): berserk, you attack the nearest unit, your allies first.

When an enemy survives thanks to Bailout (W), back off rather than offer a kill: they lose their health over 3 seconds, and only a takedown saves them.
