Aurora vs Sett

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.

Get out of the center of Haymaker (W): it deals true damage there, and the sides only deal physical damage.

Keep your distance once Knuckle Down (Q) is used: he has no dash, and it's this spell that speeds him toward you.

Don't take a big trade unless you can finish it: Haymaker (W) stores part of the damage he takes as Grit, for a stronger shield and punch.

Don't stay grouped behind your tank: The Show Stopper (R) can slam them onto you, and the damage depends on their bonus health.
