Aurora vs Malphite

Poke with Twofold Hex (Q), then recast it once the target has lost health: the hex passes back through them and deals more damage the more health they're missing.

Cast Across the Veil (W) to dodge a skillshot or break a chase: you leap and turn invisible briefly, and a takedown resets its cooldown.

Cast Between Worlds (R) in the middle of grouped enemies: those trying to enter or leave the area are slowed, which keeps them under your team's spells.

Inside Between Worlds (R), teleport from one edge to the other to dodge skillshots and reposition, as long as the area lasts.

Break Granite Shield (passive) with a cheap hit before taking a real trade: it absorbs 10% of his max health and triples his bonus armor.

If you deal magic damage, lean on it in trades: his only resistances come from Thunderclap (W), which only gives armor.

Trade when his mana runs low: Seismic Shard (Q) costs 70 to 90 mana, and it's his only ranged slow.

Once he hits level 6, only step up if he's visible: Unstoppable Force (R) comes from far away, nothing stops it, and its impact knocks every enemy in the area into the air.

When he has Unstoppable Force (R), spread out from your allies in teamfights: the impact knocks every enemy in the area into the air.
