Xayah vs Swain

Cast a spell before your autos: with Clean Cuts (passive), they pass through every target in their path and each leave a feather to call back.

Activate Deadly Plumage (W) before a trade: you gain attack speed, each auto fires a second blade, and hitting a champion makes you faster.

Position yourself so that Bladecaller (E) pulls your feathers back through your target: at least 3 feathers have to hit them to root them.

Cast Featherstorm (R) to dodge a decisive spell: you're untargetable for 1.5 seconds, then you leave a line of feathers to call back with Bladecaller (E).

Get out of the Nevermove (E) path as it comes back: it only roots on its return to Swain, then he can pull each rooted champion to him.

Leave the area as soon as Vision of Empire (W) appears: it strikes and slows 1.5 seconds later, and each champion hit gives him a Soul Fragment.

During Demonic Ascension (R), back off and hit from range if you can: he only drains nearby enemies, and his form ends when he stops draining.

If you have Grievous Wounds, apply it during Demonic Ascension (R): the drain heals him every second, and that healing keeps him alive.
