Sustain items, namely health regeneration, lifesteal or spell vamp. Jayce is above all a poke champ, and sustain counters poke. The rest is sort of dependent on how he builds: if he's building full AD, build armor. If he's building like a fighter and getting tanky items, build magic resistance, as he'll be getting in melee range and trying to deal lots of damage through his W+E. Health works somewhat too, though in that case you may want to kite Jayce when he's in hammer form form more. In general, and both its upgrades work well against him, as do  and.
