How to play as Ashe
Avoid trading into Jhin's 4th shot; after he uses it on a minion, look for an extended trade with attacks and Ranger's Focus(Q). Keeping the wave closer to your side gives you room to chase him with your slows.
Jhin's four-shot attack pattern limits his sustained basic attacks, while Ashe's Frost Shot(P) slows targets she attacks and helps her keep pressure on him in longer fights.
If Ashe's Enchanted Crystal Arrow(R) hits Jhin while he channels Curtain Call(R), its stun interrupts the channel.
How to play as Jhin
Favor short trades with Dancing Grenade(Q) and your 4th shot, then back out; Ashe's slows and Ranger's Focus(Q) let her win if the fight keeps going.
Don't channel Curtain Call(R) while Ashe can line up Enchanted Crystal Arrow(R); she can stop your shots with the stun, so wait for her arrow or break the channel if it is coming.
