Jinx vs Varus

Poke with Fishbones, the rocket launcher of Switcheroo! (Q), for its range and splash damage, then swap back to the minigun for long trades.

Fire Zap! (W) to kite the bruiser running at you or catch an enemy who's fleeing: it slows and reveals the first enemy hit.

Throw Flame Chompers! (E) in the path of their engage or their escape: they root the champion who steps on them and last 5 seconds.

In teamfights, focus the lowest-health target first: each takedown triggers Get Excited! (passive), a big boost to attack speed and move speed.

Fire Super Mega Death Rocket! (R) to finish a fleeing enemy rather than to start a fight: its damage grows with their missing health and over its first second of flight.

Back off after taking a few autos: each one applies a Blight stack from Blighted Quiver (W), and his spells detonate them for damage based on your max health.

If you can engage, go in while he charges Piercing Arrow (Q): charging slows him, and he has no dash to escape.

Get out of the Hail of Arrows (E) zone fast: the desecrated ground slows you and reduces the healing you receive.

When an ally is caught by Chain of Corruption (R), move away from them fast: the corruption spreads to nearby champions, but dies out if you get far enough in time.
