Jayce Build Guide by Vikkto
Mastery Tree Is Outdated
WARNING: These masteries are still using the old tree and have not been updated to the new tree by the guide author. As such, they will be different than the masteries you see in-game.
Currently this guide is mainly for Solo Top. All I currently have for AD carry is the item build, masteries, and runes. Once I am finished with the solo top portion of the guide I will add more info on AD carry Jayce.
This is my guide for Jayce - The Defender of Tomorrow. Personally I prefer playing him as a solo top, but I have been very successful playing him in the AD carry role as well.
As with any guide, this is simply a basic outline of how I personally build. There will and should be variation from game to game depending on who you are matched up against in lane. Later on I will discuss some of the situational items as well as my basic strategy against some of the common enemies you will see in lane.
This is my first guide, so I'm still learning how to set up guides with this site. I will be continually updating the guide to add more information and to make it look more visually appealing. Of course if you have any suggestions feel free to leave a comment.
Armed with wit, charm, and his signature transforming hammer, Jayce lives to protect his native Piltover. He rose to prominence as an inventor, one whose magnetic personality and innovative creations brightened the lives of his nation's people. However, his technological marvels also attracted the attention of Piltover's enemies. Viktor, the machine-augmented scientist from Zaun, staged a deadly raid on Jayce's laboratory, barely impeded by the lab's meager security force. Viktor stole designs for an arcane power converter. Jayce feared that Viktor would create weapons of devastating power with the stolen technology. He implored the Piltover government to respond, but the officials were unwilling to support an act of aggression. Refusing to allow his own inventions to threaten the people of Piltover, Jayce decided to strike back against Viktor himself.
Jayce returned to his laboratory and began making preparations for his one-man attack. After an intense period of research, development, and hands-on testing, he emerged. He had created an array of powerful armaments, including his crowning achievement – the versatile, transforming Mercury Hammer. Armed and ready, Jayce began his assault, easily smashing aside Viktor's acolytes as they rushed to stop him. Jayce fought his way into the heart of the lab and confronted Viktor, forcing the Zaunite to flee. After destroying Viktor's prototype weapon, Jayce returned to Piltover where he was hailed as a hero. He reveled in the adoration, but he knew that his actions had provoked the nation's enemies. Now devoted to the defense of his people, Jayce is Piltover's best hope for a bright future.
"Trust me: if we're smart, Piltover can stand strong against any threat. Hey, I'm living proof."

Early game farming with Jayce is pretty easy. With flat AD runes you will start with 69 AD and can sit back with Mercury Cannon to avoid taking too much unnecessary damage. Acceleration Gate/Shock Blast combo is a good way to quickly clear waves. When you run low on mana or whenever the enemy goes back, switch to Mercury Hammer to farm. This gives you mana each time you land a basic attack. Be careful doing this if you are against a ranged champion though, as it will make you easier to harass.
Once you have wriggles and phage farming becomes very easy. If my enemy has good pushing ability, I like to acceleration gate/shock blast the caster minions. By this point in the game it should 1 hit them, giving you 3 cs each time. From there just last hit the rest of the minions. Once again if you need mana, switch to Mercury Hammer.
By this point in the game farming should be no problem. Use your various skills to quickly clear waves when there isn't a team fight brewing.
Solo Top Items
Boots of Speed + 3 Health Potions - I ALWAYS start with these items. Not only does it give you more speed to avoid any incoming skill shots, but the health pots help you stay in lane much longer.
Wriggles Lantern - Usually by my first trip back I can afford my Wriggles. This is a great sustain item, as well as free wards and easier farming.
Mercury Threads/Ninja Tabi - I usually go with Merc Threads for the tenacity, but if you are against a heavy AD team then Ninja Tabi may be the better and cheaper choice.
Heart of Gold - If you are being zoned out of your lane, grab this early. It will give you GP/5 plus some health that may help you stay in lane a bit longer. It can be sold later on.
Phage - I try to get this early for the slow proc, extra health, and damage. If you are struggling against an AP solo top, you may want to grab Wit's End or Hexdrinker first.
Wit's End - Wit's End is relatively cheap and is great for the huge attack speed increase and magic resist. Personally, I get hexdrinker over Wit's on Jayce, but it's not necessarily a bad choice.
Hexdrinker - Spellshield and MR. If you're not against an AP top or heavy AP team there may be better items to go with altogether.
Frozen Mallet - The item I get after phage depends on who I'm laning against. This is usually my first major item on Jayce. The slow and health work good with Jayce.
Maw of Malmortius - Maw of Malmortius is great for the spell shield and magic resist. On top of that it grants some AD, which is always helpful.
Trinity Force - Trinity Force adds a lot of extra damage. Jayce's damage relies heavily on chaining skills together, so procing the passive damage increase from Trin Force is never an issue.
Atma's Impaler - With a major focus on health in this build, atma's is good not only for the increased damage but also the extra armor.
Warmog's Armor - If you decide you don't need Wits End, this is a great item to have in your build. It will grant you more damage thanks to Atma's, as well as make you harder to kill due to the health and health regen it grants.
Enemy Matchups (Solo Top) [UNDER CONSTRUCTION]
Riven, the Exile - Hard - Riven is an incredibly tricky champ to beat. All it takes is a 1-2 kill advantage and she will win the lane with ease thanks to her mobility, shield, and high damage. Best strategy against her is to not push and just farm in cannon mode until your jungle comes to gank.
Fiddlesticks, the Harbinger of Doom - Hard - I've only had this happen once, and it was because I was zoning Darius hard so they switched lanes. Get merc treads early and ward often. If acceleration gate is on CD stay out of fear range. Fear + Gank can be hard to get away from.
Garen, the Might of Demacia - Hard - If you can't get an advantage early game he will run in, silence, spin, then go hide until he has regenerated. Once he starts building armor he will zone you easily.
