Aphelios vs Kalista

With Gravitum as your main weapon, hit your target to slow them, then cast Weapon Abilities (Q): the cannon roots every enemy it has slowed.

Switch to the right weapon with Phase (W) before Moonlight Vigil (R): you then attack each champion hit with your main weapon, and its effect applies.

Before an objective, check Weapon Queue System (E): it shows the weapon Alune will give you next, and an empty weapon goes to the back of the queue.

After a trade, back off until her spears fall out: they stay stuck for 4 seconds, and Rend (E) deals more damage for each extra spear.

Cast your spells as she starts an auto: she can't cancel the animation, and Martial Poise (passive) only makes her hop once the shot is out.

Focus her Oathsworn when you can: without them, Fate's Call (R) has no one to throw, and Sentinel (W) loses its bonus damage.

When Fate's Call (R) pulls in her Oathsworn, spread out: they can launch within 4 seconds, stop at the first champion hit and knock back nearby enemies.
