Aphelios vs Twitch

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.

Get out of the Venom Cask (W) cloud fast: it slows you and adds a Deadly Venom stack every second, which powers up his Contaminate (E).

Ward your brushes and place a Control Ward on his paths: it reveals camouflaged enemies, and Ambush (Q) lets him reach you unseen.

As soon as he comes out of the Ambush (Q) camouflage, focus him with your allies: he's fragile and has no dash to escape.

During Spray and Pray (R), get out of his extended range until the effect ends: his bolts pierce every enemy, so hiding behind an ally won't protect you.
