Jinx ADC vs Thresh Support Matchup

How to play as Jinx

Position behind allied minions to block Death Sentence(Q); once Thresh misses his hook, immediately step up to punish him with Fishbones(Q) rockets during his 19-second early cooldown window.

Do not panic-throw Flame Chompers!(E) forward in neutral; hold them until Thresh commits forward to walk past minions or attempts a Flay(E), cutting off his path.

Flame Chompers!(E) interrupts dashes, so placing Chompers between Jinx and Thresh halts his Death Leap (Q recast) mid-flight and roots him in place.

Thresh does not gain armor per level from base stats, relying entirely on collecting souls with Damnation(P) to scale his physical durability, making him surprisingly fragile to basic attacks early.

Fishbones(Q) gives Jinx 600 or more attack range, comfortably outranging Thresh's 450 basic attack range and 500 range on Flay(E).

How to play as Thresh

Hold Death Sentence(Q) rather than fishing for max-range hooks; the threat of your hook forces immobile Jinx to forfeit CS and space defensively, whereas missing it leaves you vulnerable to free rocket poke.

Use brush control and minion gaps to walk into range for a Flay(E) slow first instead of leading with Death Sentence(Q), guaranteeing an easy hook follow-up on Jinx.
