Yunara vs Swain

Hit with Arc of Judgment (W) before a trade: the prayer bead slows your target, then damages them every second, and it reaches 1150, well beyond your autos.

Measure your power by your crit items: with Vow of the First Lands (passive), each of your critical strikes deals bonus magic damage.

Once your autos have charged Cultivation of Spirit (Q), activate it for a trade or a teamfight: you gain attack speed, and your autos spread to nearby enemies.

Cast Transcend One's Self (R) as the teamfight starts: your basic spells are upgraded, Arc of Ruin (W) fires a laser, and Untouchable Shadow (E) gives you a dash.

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.
