Introduction (HD Video)

Superman + The Incredibles = FACT

I think you will find Jayce to be one of the most interesting and fun champions to play because of his versatility and synergy between abilities. I mean…You can create combos and then chain them together! Only a superhero can do that!

Video explanation of Jayce's abilities.

Use the links at the top of the video to skip around.

What this guide will do:
-Encourage players to play Jayce like a superhero!
-Encourage the discovery of cool chained combos! While providing a few viable options for building Jayce
-Assume that you have played Jayce at least once already and have a basic understanding of his abilities.

What this guide will not do:
-Tell players that there’s only one way to play Jayce
-Tell players that there is a “right way” and a “wrong way” to play Jayce, because there isn’t! Just have fun and look like a superhero while you do it!

NOTE: This is my very first guide so please be kind! It is still under development. was released just a few days ago so give me some time and ill have multiple builds, videos, the works!

Pros / Cons


+ He’s’ a Superhero! Heck, we could end the list right here!

+ Has a ridiculous skill shot nuke from afar

+ Has many different ability combos and synergies as well as versatility

+ His AD scales very well in all game phases. Early, Mid, and especially late.


- Jayce doesn’t like Viktor (but who does?)

- Somewhat squishy, if you aren’t careful. But don’t worry! We have a remedy for that!

- Kind of slow even with Level 2 boots. Ability speed boosts make up for that.

Combos (HD Video)

OK, this section is the fun part of the guide. In this section I will present to you a few different combos and ways to chain those combos together like a superhero! These are just suggestions and there is no “correct” or even “best” way to do things. I personally just want to have fun and look like a superhero while playing Jayce, and that's probably why you are here too! :) Metropolis / Metroville will never be the same!

Below you'll find a video highlighting a few ways to put some of the combos together.

Power Blast!

While in Mercury Cannon stance: E+ Q

Place your E down between yourself and a villain(enemy champion) or group of minions, then send your Q through it for “Tons of damage!” After that, you can run through it yourself for a speed boost to prepare for another combo!

Accelerated Hyper Charge!

While in Mercury Cannon stance: E+ W

Place your E down in front of you while running toward a villain. Then, when you are within range, activate your W for three quick auto attacks.

Thunder in the Skies!

Start in Mercury Hammer stance + Q+ E

Use your Q to close the gap between yourself and a villain. Then Run in front of them while they are slowed. Once you are in front, knock them back toward your team with E or finish the kill with it if they are low enough.

Hammer Time!

While in Mercury Cannon stance: W+ R+ Q

This one is fun, and makes you look like a total superhero! While in ranged stance, activate your W, then transform to melee stance and use your Q on a villain! You’ll slow them from the Q, then attack them three times with your hammer very quickly. Definitely a superhero move!

Static Thunder in the Skies!

Start in Mercury Hammer stance + Q+W+ E

While in melee stance, use your Q on a villain but while you are in mid air activate your W for the AOE damage. Then use your E when it’s appropriate, ie for the kill, or to knock him to your teammates.

Thunder in the Skies! to Transform-Hypercharge!

Start in Mercury Hammer stance + Q+ E+ R+ W

Here’s a chained combo! While in melee stance, use your Q on a villain, then knock him away with your E. Now use your R to switch to ranged mode. Then activate your W for three quick auto-attacks. From here you can E to retreat through your gate then send a shock blast back through it if they are naïve enough to follow you!

At level 1, start with your:
Q then E , then W by level 3.

With many champs, we like to start with our Q ability and rank it twice by level 3 for early poking. Well, we all like poking :) but Jayce, is a very clever superhero and I think that having all 8(ult counts as 2!) of his abilities by level 3 is the best way to dish out maximum damage and have a little crowd control in case you attempt an early kill with your laning partner if you have one.

If you are building AD Superhero...

-Concentrate on ranking his Q ,
-Then rank up his W and E evenly as you level up for the versatility and damage in mid-game fights.
-Rank up his R whenever it’s available.

If you are building AD glass cannon...

-Concentrate on ranking his Q ,
-Then W because after rank 3 this ability absolutely wrecks people!
-Rank up his E last, then R whenever it’s available.

I will give two separate builds here, Superhero!(Bruiser) and AD Glass Cannon. I will provide an explanation of the AD Glass cannon build for now, and then in a day or two Ill have more info on the Superhero! Build. Although, honestly the superhero! build is pretty self explanatory. It provides, +Damage, +Health, +Armor for early to mid game skirmishes. Then, the last few items are completely situational no matter your path.

“Boots pots” is a good way to start on many champions, especially AD’s. Boots will give you enough speed to get in and out of early game fights as well as get to minions faster for last hitting. The health potions are great for recouping HP after early game skirmishes. Don’t forget to use your potions!

Get 2 of these when you have 950 Gold. They are great way to pick up early game health, attach damage, and a little lifesteal. Jayce is a bit squishy when building full AD, and his ranged auto-attack is kind of short so we need the extra health to survive while we farm cs (CS=Creep Score). After your two finish your as Berserker’s Greaves

From here you must choose a path…
Superhero! or Glass Cannon


Glass Cannon:

I know, I know. You are thinking “it’s going to take me forever to get 1650 gold! Truth is, if you are farming correctly, you’ll get that 1650 earlier than you think. Especially if you are able to sneak in an early kill or a few assists. After you get the work toward the by purchasing then


Glass Cannon:

To the edge of infinity, and beyond! Wait…what was I talking about? Oh right, grab your infinity edge asap. “Why infinity edge?! Jayce is not a critty superhero! Dummy Trev!” Take a close look at it. 25% crit chance from one weapon is not to be scoffed at and neither is the crit bonus damage. The point of the infinity edge ultimately is to pack the biggest possible punch in one item slot. Don’t overanalyze it, don’t think too hard, just buy it and watch the bodies hit the floor once you activate W


Glass Cannon:

By this time you are probably entering mid game and sustainability becomes a bit more important. Because of how mobile Jayce is, you’ll find that you can enter the fray and probably make it out by the skin of your teeth in some cases. The Vamp Scepter combined with the AD from doran’s and the Infin. Edge will make lifestealing your health back from minions or the jungle.


Glass Cannon:

Finish the Vamp Scepter with this. It offers good attack Damage, and great lifesteal after you have farmed it up a bit on minions. Try not to die after purchasing it though or you’ll lose about half of your bonus lifesteal.


You can finish the phage as a or build it into a . The mallet is really just a beefier version of the phage. More AD and more HP for our superhero with a slow to boot!

The on the other hand offers many different things, all of which are beneficial to this type of champion. Below I have listed all of the stat increases to this item, but the “Unique:” portion makes this very powerful. It gives us extra attack damage on the next autoattack after using an ability which synergizes very well with Jayce.
+30 ability power
+30 attack damage
+30% attack speed
+15% critical strike chance
+250 health
+250 mana
+12% movement speedPassive Unique: Your basic attacks have a 25% chance to slow your target's movement speed by 35% for 2.5 seconds.
Unique: After using an ability, your next basic attack deals bonus physical damage equal to 150% of your base Attack Damage. 2 second cooldown.


Choose what suits you best from these items. The basic AD carry build from this point is pretty much complete. It is late game now though, and we have to decide how to react to Lex Luthor or “Syndrome”!!


A second blood thirster will give you even more sustainability into late game however it does not provide any pure survival stats so be careful! Only true superheros can pull this off!

If you are doing well, confident in your survival skills, and want to continue building more AD feel free to! The black cleaver provides more AD, attack speed, and an armor debuff that stacks 3 times for a total of 45 armor reduction to your target! The cleaver provides nothing for survival! Not even Lifesteal! So again, be careful this purchase as well.

This mastery provides many improvements to what many consider the offensive summoner spells. Since I have taken this mastery will also debuff the target, removing a bit of their armor and magic resist. This mastery unfortunately does not improve my in any way, however if I chose to remove in exchange for I could benefit from the increased movement speed bonus to my summoner spell.

The extra 3 points of attack damage from this mastery help us to get easier last hits on minions as well as poke our enemies with combos. As you have probably noticed, having extra attack damage early in the match is a constant in this guide.

+4% increased attack speed is never a bad thing for an AD superhero and it goes well with your ability for those three quick attacks. The real reason we want this mastery however, is for the the one that it leads into,

Armor pen lets your attack damage abilities as well as auto-attacks ignore a percentage of the opponent’s armor. Because Jayces abilities scale so well with his attack damage, we only need a small amount of this for now which makes perfect !

This gives us 0.5 attack damage per level for a total of [+4.5 at level 9] or [+9 at level 18] Not spectacular in my opinion but every little bit helps! This leads us into into which isn’t half bad either!

+10% critical strike damage means that your critical strikes will hit for 210% of your current attack damage. If you purchase the then your critical strikes will hit for 260% with this mastery !! Amazing!

+3% lifesteal gives us back a small bit of health from our auto attacks. You won’t notice much from this until later in the game when you have purchased some of your damage items. 3% of 100 attack damage for example is only 3HP returned to you. But but but!! Later in the game you will have a which builds into a The Blood Thirster(20%) for a total of 23% lifesteal!!

More armor Penetration! Everyone likes penetration right? +6 more armor pen for a total of +16 armor pen from this build will be enough until late game when we may want to consider more armor penetration items to counter high armor items that Lex Luthor will purchase.

Finish off your foes! This mastery gives your superhero +6% extra damage when the villain you are attacking is under 40% health. An offensive mastery indeed!


2 points into each of these masteries gives us an additional +4 armor and magic resist for the times that we are in the fray in downtown Metropolis!

but not
This mastery gives us additional health per level. This is useful for when you are feeling ballsy and want to switch into melee stance for crowd control, or to catch a runner! I avoid because 30 health isn't much so instead I put that point into because damage mitigation will generally take you farther than flat health. If you decide to take no problem! +30 health won't hurt.

Greater Mark of Attack Damage

Greater Seal of Armor

Greater Glyph of Magic Resist

Greater Quintessence of Attack Damage

Greater Mark of Strengthx9
Flat damage runes give us early game harass and easier creep score, which is extremely important with Jayce. I avoid going with armor pen these days because the advantage that we get from early game AD makes farming minions much easier as well as poking even though Armor pen runes will make you hit like a truck late game. Thankfully, AD scales extremely well late game with Jayce’s abilities Hyper Charge and Shock Blast so armor pen isn’t an absolute necessity.

Greater Seal of Resilience sizex9
The extra armor from resilience runes goes great along with the additional armor Jayce gains while in the Hammer stance. This way you can have more survivability and versatility, no matter how you choose to build with your items as the game plays out.

Greater Glyph of Shieldingx9
The magic resist from these runes will give you more survivability for the times that you are hammering Transform: Mercury Hammer champions or minions at the front lines of battle to either close the gap with or knock them toward your team with

Greater Quintessence of Strengthx3
These flat AD quints along with the flad AD marks will make it a bit easier for you to last hit minions and poke enemy champs who come a bit too close early in the game as well as make people QQ about how OP your E +Q ranged combo combo is.

Summoner Spells

This is pretty much a safety net to me for when situations get sticky!. I use flash on most of my champs and in most of my builds. If you haven’t used Flash before… it teleports your champ to a location not far from your current location, however it is just far enough to get out of a fight, or even into one for that matter. Just place your cursor a short distance away from your champion and press the button.

Ignite is great for catching a runner without actually catching them. Just before they are outside of the ignite range while they are running, place the ignite on them for the finish! Its like bug spray! You may not see the bug die, but you know he will eventually! It is also good for negating any heal-over-time ability than another champion may have.

is another great way to catch a runner, and it gives the enemy a debuff to armor and magic resist to boot!
can be replaced for if you have good timing. This ability will make you look like a true superhero as you zoom around beating on people.
