Best Jayce Build Guide | Runes | Spells | Items in League of Legends

Anyone's first time using the 'Defender of Tomorrow' in League of Legends will find it confusing to see the "ultimate" ability unlocked right at the beginning of the match. To play Jayce like a pro and get the most out of his versatility, players need to carefully study his skill order to make the most out of his physical damage regardless if you play him in the top lane or mid lane.

Best Jayce build

This best Jayce build covers everything you need to know for him, from his Summoner Spells and Rune set, to his best mythic items, and skill order so you can deal damage in quick successions to your enemies. Are you ready to carry in the Summoner's Rift with Mercury Hammer?

Best Jayce Runes

For starters, Jayce's best rune set is a combination of the "Sorcery" tree and the "Inspiration" one. For the "Sorcery" rune set, equip "Phase Rush", then, follow up with "Manaflow Band", "Absolute Focus", and "Gathering Storm". "Phase Rush" works well with Jayce since it's really easy to activate thanks to his combos and switch of stances.

Best Rune Path	Sorcery	Inspiration
Best Keystone	Rush Phase
Best Slot 1 (Rune)	Manaflow Band	Magical Footwear
Best Slot 2 (Rune)	Absolute Focus	Biscuit Delivery
Best Slot 3 (Rune)	Gathering Storm

In the second rune set, use "Inspiration" and chose the runes "Magical Footwear" and "Biscuit Delivery". Note that some people chose "Inspiration" with the "First Strike" keystone, but "Sorcery" works quite well for him as well.

Best Rune Shards

For his Rune Shards, you are going to choose "Adaptive Force" in the first two sockets to ensure more damage in the laning phase of any League of Legends match, you can certainly use the Mercury Cannon to poke your enemy.

Best Rune Shards	Effect
Flex	9+ Adaptive Force
Offense	9+ Adaptive Force
Defense	6+ Defense

Complete your rune shards with the "Defense" to resist more damage, which you will receive when you lunge at your enemy with the Mercury Hammer.

Best Jayce Spells

Jayce's best spells are "Flash" and "Teleport", being the first the usual pick for most characters in League of Legends. You can use "Teleport" to combine your attack speed and each of your abilities.

"Teleport" is excellent to get back to your lane as fast as possible if your enemy kills you, or if you survive an encounter and went to your base to buy items.

Best Jayce Abilities Order

Jayce's best skills order starts with his Q ability "To The Skies - Schock Blast", you might want to use Shock Blast in the laning phase to poke your enemy, and you don't need much attack speed for it. Continue with "Lightning field - Hyper Charge", and the good thing about "Lightning Field Hyper Charge" is that it restores mana passively, so you shouldn't have much trouble with it.

And lastly, you want to level up your E ability "Thundering Blow - Acceleration Gate". A good combo with Jayce would be: "To The Skies - Shock Blast", "Thundering Blow - Acceleration Gate", auto attack, "Lightning Field - Hyper Charge", "Mercury Hammer - Mercury Cannon", "To The Skies - Shock Blast", "Lightning Field - Hyper Charge", auto attack, and "Thundering Blow Acceleration Gate".

Best Jayce Items

In this Jayce build his best items are quite simple, and despite having a passive ability that restores mana to him, he still uses an item that derives from the "Tear of the Goddess", which is the "Manamune".

Best Jayce Starter Items

For starters, "Doran's Blade" is great for "Shock Blast" to deal serious damage from the beginning. The HP potion and the "Stealth Ward" are obvious choices for the beginning of every match.

First Item	Second Item	Third Item
Doran’s Blade	Health Potion	Stealth Ward

Best Jayce Mid Game Items

When you reach the middle of the game, it will be easy for you to activate Phase Rush while you deal burst damage to your enemies. The "Eclipse" is part of his core items and along with the "Ionian Boots of Lucidity", Jayce becomes quite annoying to be against.

First Item	Second Item	Third Item
Eclipse	Ionian Boots of Lucidity	Manamune

The cherry on top is the "Manamune", which gives him a big advantage to use abilities such as "Thundering Blow - Acceleration Gate" freely and without worrying about mana, this way he can be hitting his enemies all the time.

Best Jayce Final Late Game Items

With his full build, Jayce's attack damage becomes worthy of respect, and when executing his abilities in the right skill order, he could one-shot enemies without much trouble... Of course, this takes practice when it comes to Jayce.

First Item	Second Item	Third Item	Fourth Item	Fifth Item	Sixth Item
Eclipse	Ionian Boots of Lucidity	Manamune	Serylda’s Grudge	Youmuu’s Ghostblade	Maw of Malmortius

"Serylda's Grudge" becomes valuable for Jayce because it slows downs the enemy he attacks, that way, he can land his attacks with Mercury Hammer and Mercury Cannon. The Maw of Malmortious is also an excellent way to survive magic damage.

Best Champions to Pair Jayce With

Maokai, Elise, and Rammus are all excellent to pair with Jayce thanks to the crowd control they provide to him.

Champion	Win Rate %	Icon
Maokai	55.0%
Elise	54.1%
Rammus	53.2%

Combining that with "Serylda's grudge" and "Ionian boots of lucidity" allows Jayce to secure a kill, hence these are the highest win rate Jayce has.

Strongest Champions Against Jayce

But because no champion is perfect, Jayce's counters are Sejuani, Olaf, and Nasus. Which are all tough matchups for him since he has no advantage in melee stance against them whatsoever.

Champion	Win Rate %	Icon
Sejuani	42.3%
Olaf	43.6%
Nasus	43.9%

Weakest Champions Against Jayce

Lastly, the highest win rate Jayce has is against these characters. "Maw of Malmortius" is the reason why Jayce comes victorious after fighting these assassins, so don't forget to equip it.

Champion	Win Rate %	Icon
Kayle	55.0%
Akali	54.0%
Kennen	53.7%

Jayce is a difficult champion to play, we won't sugarcoat that, but that shouldn't discourage you if you want to learn how to use him, especially because once you have mastered him, and his playstyle, it has quite a good payoff that you will surely enjoy. Good luck Summoners!
