Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Hello, my name is DJ Ari Oozil, and this is my guide to Jayce, the Defender of Tomorrow. Jayce is a very strong mid and top laner, and is a niche pick in the ADC role. This guide will be mainly about mid and top lane, but will have a few notes about the ADC role. This is my first guide, so any and all feedback would be appreciated. If you want to contact me in game, my summoner name is DjAriOozil, and I am in North America.
Pros / Cons
Ranged and melee
7 different abilities
Has a knockback
Very strong Mid Game and Late Game
No guaranteed escape
No real ultimate
Managing forms is somewhat difficult
Greater Mark of Lethality
Greater Seal of Armor
Greater Glyph of Magic Resist
Greater Quintessence of Attack Damage
lllllSeals: On Jayce, I like to take 9 Greater Seal of Armor. This will help you survive the early game against AD mid laners, which have been very common lately. If you aren't against an AD mid laner, or if you believe you can easily beat an AD mid laner, another possible choice is 9 Greater Seal of Scaling Health. This is a very strong rune that will give you almost 250 health late game.
lllllGlyphs: On Jayce, I like to take 9 Greater Glyph of Magic Resist. This gives you early magic resistance, and should make your laning phase against AP mid laners much easier. I take this in all situations.
lllllQuintessences: On Jayce, I like to take 3 Greater Quintessence of Attack Damage. This is a very strong rune that will give you quite a bit of attack damage early game, and will help all game.
MasterieslllllFor the Cunning Tree:
lllllI prefer Wanderer over Savagery . Wanderer gives you more movement speed out of combat, which will help you walk to lane and roam faster. This is better than Savagery . Savagery is only better if you have trouble last hitting, or really want to push your wave. If either of those two is true for you, then Savagery is better than Wanderer .
lllll Assassin is the best of the three, because while the other two, Runic Affinity and Secret Stash give minor sustain, Assassin increases your damage throughout the entire laning phase, and most of the rest of the game.
lllll Merciless is better than Meditation because slight conditional damage is almost always better than slight mana regeneration.
lllll Dangerous Game is better than Bandit , because while Bandit gives a small bit of income, the healing from Dangerous Game can save your life in a close 1v1, and in a teamfight, it can heal you for up to 25% of your missing health and mana.
lllll Precision is better than Intelligence because armor penetration is a boost to your damage, while CDR allows you use your abilities more often. Both are good on Jayce, I just personally prefer Precision .
lllll Thunderlord's Decree is the best of the three, because it adds to your burst, while the others are utility focused and almost useless on Jayce.
lllllFor the Ferocity Tree:
lllll Sorcery is better than Fury because ability damage is better than attack speed, due to the fact that Jayce already gets the maximum attack speed from his W Hyper Charge.
lllll Double Edged Sword is better than Feast , because damage is better than sustain for Jayce. Still, Double Edged Sword is double-edged, and it will increase your damage taken. However, Jayce is a poke champion, so he will spend more time doingdamage than taking damage.
lllll Vampirism is better than Natural Talent , because Vampirism is a very nice mastery for sustain in difficult lane matchups. It gives 2% lifesteal, which is almost as much as Doran's Blade. The 2% spellvamp is very nice as well, giving you lane sustain. However, if you are very confident in your lane, or you just want as much damage as possible, no matter how small, then Natural Talent is a viable choice.
lllll Bounty Hunter is better than Oppressor , because Jayce has very little Crowd Control, so Oppressor won't increase his damage. Bounty Hunter , on the other hand, increases your damage for each unique kill you get. By mid game, you should have at least 2 unique kills, increasing your damage permanently. That is why I believe Bounty Hunter is better.
lllllJayce is the only champion that can't put points into his R. Instead, his basic abilities have 6 available points.
lllllFirst, you'll want to max Jayce's Q To The Skies! / Shock Blast. It is his main ability, his gapcloser, his poke, and his damage. In Cannon Form, it is a long range skillshot that explodes on the first target it hits, creating a small blast radius, dealing damage to all enemy units in the area. In Hammer Form, it is a targeted gapcloser, dealing damage and slowing in a small circle around the target. This is a very powerful ability. Max this first.
lllllSecond, you'll want to max Jayce's W Lightning Field / Hyper Charge. In Hammer Form, it creates a small damaging field around Jayce, dealing minor damage. In Cannon Form, it makes his next 3 basic attacks fire at a rate of 2.5 attacks per second. This is the maximum attack speed. This gives him surprising damage, and late game, can allow you to 3 shot squishy targets. The damage of the 3 quick attacks gets higher as you put points into this. Therefore, max this second.
lllllThird, you'll want to max Jayce's E Thundering Blow / Acceleration Gate. In Hammer Form, this is a melee range knockback, dealing damage based on the enemy's maximum health. This is a somewhat useful ability, as it can get an enemy away from you, or you can use it to knock an enemy into your team. The damage is very mediocre, which is why I put the least priority on maxing this ability. In Cannon Form, it puts up a gate of energy, and gives movement speed to any allies walking through it. Also, if you fire a Cannon Form Q Shock Blast through a Cannon Form E Acceleration Gate, it increases the range, speed, damage, and blast radius of the Q Shock Blast. While this is incredibly useful and powerful, the enhanced Q damage does not increase when you put points into the E, only the Q. Therefore, I consider E Thundering Blow / Acceleration Gate to be the ability that requires the least amount of points. Max E last.
lllllJayce's R Mercury Cannon / Mercury Hammer switches the form of Jayce's weapon from Hammer to Cannon, or from Cannon to Hammer. You cannot put any points into this ability, and it automatically gains power at levels 1, 6, 11, and 16. While in Hammer Form, your armor and magic resistance are increased. Additionally, switching forms enhances your next basic attack. When switching into Hammer Form, your next basic attack will deal bonus magic damage. It gives you a little bit of extra burst. When switching into Cannon Form, your next basic attack will reduce your target's armor and magic resist for 5 seconds. This will allow you to deal more damage to tanky targets.
lllllJayce's Passive Hextech Capacitor increases Jayce's movement speed whenever he uses his R. This is handy when traveling long distances, or when chasing or escaping.
Muramanalllll Muramana is an incredibly powerful item on Jayce. It provides an insane amount of mana, which Jayce can use to poke the enemy team for a very long time without needing to recall. The active is very nice as well, especially when combined with Jayce's W, Hyper Charge, which will proc it 3 times.
Youmuu's Ghostbladelllll Youmuu's Ghostblade is a very strong item on Jayce. It gives him almost all of the stats he needs: AD, CDR, Armor Penetration. The active is very nice as well, and it can be used for chasing, escaping, pushing down turrets, and much more.
Essence Reaverlllll Essence Reaver is also a nice item on Jayce. It gives him more power against close range targets from the critical strike chance, and provides 20% CDR once Infinity Edge is finished. A very nice item
Infinity Edgelllll Infinity Edge is an item that is usually paired with Essence Reaver, as it increases the CDR of Essence Reaver, and increases the close range damage of Jayce even further.
The Black Cleaverlllll The Black Cleaver is a situational item. If you get it, you should not usually get Essence Reaver or Infinity Edge. It gives you a medium amount of health, armor shred, attack damage, and the rage passive that will help you kite better. I usually get this when I need to be more poke-focused, and close range fighting isn't happening much. I get this every time on top lane Jayce, and it is common for top lane Jayce to build Muramana, Ionian Boots of Lucidity, Youmuu's Ghostblade, The Black Cleaver, and two defensive items, turning him into a poke-heavy bruiser. This isn't bad, in fact it's quite good, I just personally prefer a more assassination focused Jayce. Still, it's your choice what you want your Jayce to be.
Duskblade of Draktharrlllll Duskblade of Draktharr is a good item against tanks. However, it leads towards a slightly different play style. When built, it should be instead of Essence Reaver and Infinity Edge. You should build your standard Muramana, Ionian Boots of Lucidity, and Youmuu's Ghostblade. Then you should build The Black Cleaver, followed by Duskblade of Draktharr, and a last item, which should probably be Lord Dominik's Regards or Mortal Reminder. This build will increase your poke damage and increase your all-in damage against tanks, but in exchange, it will reduce your all in damage against squishy targets. I would only build this against a team with two or more tanks, and not if their ADC is fed. If their ADC is fed, a squishy assassin build would be better.
lllll Ignite is a very strong Summoner Spell on mid lane Jayce, and it gives him a bit more kill pressure in lane. This provides that little bit of extra damage that will leave you with a kill, rather than a very low health enemy running away to their turret.
lllll Teleport is a useful spell on top lane Jayce, and gives him global pressure. This could allow him to teleport gank bot, or simply to get back to lane faster. It is a very strong Summoner Spell for top lane.
lllll Heal is a nice Summoner Spell for ADC Jayce, or mid lane Jayce. It will make you live longer in teamfights, and the longer you live, the more damage you do. Get Heal or Ignite for mid lane.
lllll Exhaust is a situational Summoner Spell that is useful against assassins, like Zed, Talon, or LeBlanc. This spell could keep you alive when an assassin uses their combo against you, as it reduces the damage the target deals. I get it occasionally in the mid lane.
lllllA standard all in combo as Jayce is, starting in Mercury Cannon Form, to E+Q the enemy, then activate your W Hyper Charge, and immediately use your R to switch into Mercury Hammer Form. In Hammer Form, Q To The Skies!, W Lightning Field, use your three quick basic attacks, and then, if they're low, use your E Thundering Blow, which should finish them off, or should at least keep them away from you, because if they're not dead yet, you are probably in trouble.
This combo with buttons only, starting in Cannon Form, looks like:
("A" stands for a basic attack)
W ( Hyper Charge)
R ( Mercury Hammer)
Q ( To The Skies!)
W ( Lightning Field)
E ( Thundering Blow)
lllllAnother combo, to be used against a melee range target:
(Starting in Mercury Hammer Form)
lllll This next combo is simply an in and out combo to be done in Mercury Hammer Form. It gives your opponent little time to react, and it should be a nice bit of safe damage. To The Skies!, deal damage with a basic attack (and if you just switched to Hammer Form, it'll do the bonus magic damage as well), and disengage with your E Thundering Blow. It is a very safe combo and I use it often.
Tips and Tricks
lllllI see a lot of people using Jayce's E Acceleration Gate and then Jayce's Q Shock Blast for the enhanced damage. This does work, but there are ways to do it faster, thus giving your enemy less time to react.
llllllllllUse your Q Shock Blast and while the Q is in the air, put an E Acceleration Gate behind it. This combo feels very smooth, and while not the fastest possible way to E+Q, it is very easy.
llllllllllUse your E Acceleration Gate on top of yourself and then immediately use your Q Shock Blast. This combo is a bit difficult to get used to, and without practice some of your shots may fire in the wrong direction, but when mastered, it fires your enhanced Q Shock Blast almost instantly, giving your enemy the least amount of time to react. This is the best possible combo for Jayce's E+Q.
lllllJayce's W Hyper Charge is a basic attack reset. This allows you to press w right after you use a basic attack, letting you attack 4 times incredibly quickly.
lllllAn excellent way to quickly stack Tear of the Goddess or Manamune is to spam both of your Ws Lightning Field / Hyper Charge. Don't spam them enough to deplete your mana significantly, but do spam them enough to get a nice charge on your Tear of the Goddess or Manamune.
lllllJayce's Passive, Hextech Capacitor, give him movement speed whenever you use your R Mercury Cannon / Mercury Hammer. Your R costs no mana, so you should spam this ability whenever you are moving medium or long distances.
