What's up, guys? This is my first MobaFire guide (or forum-related guide for that matter)... so if it doesn't look pretty, I'm sorry :p

The fact that Jayce has 2 different skill-sets might make him seem a little overwhelming to some... and this part is to tell you that it's worth learning him! And he's actually quite easy to pick-up :p

Pros

+ Massive harass and easy last-hitting in lane
+ Excels at 1v1s
+ VERY fun to play :D
+ Great escape/chase
+ Built-in mana regen to his autoattacks! That means SPAM SPAM SPAM!
+ Overall just freakin' amazing :)

Cons

- Very skill-dependent
- Little sustain early game (keep 'dem pots!)
- His main counter in lane is sustain, so champions like Warwick or Udyr would be hard to get kills on (so in that case, just farm :D)

If you are familiar with the role of Solo Top at all, then you know that the team heavily depends on you to do well in order for Mid Game (team fights) to go in your favor. If you're not familiar with Solo Top, then basically this means: IT IS ALL ABOUT EARLY GAME! If you perform well in the early phase of the game, then it will carry over into Mid Game, ESPECIALLY with Jayce.

But, this also means that Early Game is the MOST IMPORTANT phase of the game as Jayce! So, there are a few key things you must do in order to secure your status as a person NOT to be reckoned with: (These are listed in order of priority)

1. Last-hitting creeps
(DO NOT push the lane to their tower until you have a Sight Ward! I usually am safe pushing to about 1/2 way between their tower and the middle of the lane (where the creeps meet at the first wave)... but NEVER go to their tower before wards!) I recommend last-hitting in cannon mode because it's easier (you have range while most Solo Tops are melee), and you can do #2 A LOT more effectively.

2. Harassing your opponent
(This means auto-attacking them with the cannon and using the almighty E+Q= BOOOOOOOM! combo (cannon-mode.) I don't recommend trying to 1v1 a melee opponent until level 4, then you have some HUGE harass.

The Wombo-Combo

Welcome, ladies and gentlemen, to the almighty wombo-combo! This combo is all the harass that you'd ever need in top, even enough to kill your opponent in just A SINGLE combo! So, without further adu, here it is... the Wombo-Combo!

Start off in cannon mode and use your E Thundering Blow / Acceleration Gate while setting-up a clear shot with your Q To the Skies! / Shock Blast... once you're sure it will hit (remember, it's AoE), launch your Q To the Skies! / Shock Blast through your E Thundering Blow / Acceleration Gate (applying the 40% buff that I already explained). This is a RIDICULOUS amount of damage, even at level 4!
Then proceed to hammer mode, jumping on top of the poor soul you're laning against with your Q To the Skies! / Shock Blast (this is AoE as well). Try to remember to activate your W Lightning Field / Hyper Charge in mid-air to start it's AoE damage too. If you can, move behind them (they're slowed, remember?) and knock them back the way you came with your EThundering Blow / Acceleration Gate, which deals a nice 8% of the max health (yes, at rank 1) too :D
Land AT LEAST one auto-attack to proc it's bonus magic damage, and then chase them, switch back to cannon mode when you can, and finish them off with a final E+Q combo.


After you perform this wombo-combo, you'll be pretty low on mana. Don't fret, though! Chances are you either killed your opponent or made them recall... so all you have to do is switch to hammer mode and auto-attack the hell outta creeps! Remember, you gain mana for each strike and the mana gained increases as you rank-up your W Lightning Field / Hyper Charge.




In order to have a successful early game, all you have to do is perform the Wombo-Combo, wash, rinse, and repeat :) That's really it. BUT! Remember your priorities!!!!!!

Farming > ATTEMPTING to kill someone (you won't ALWAYS get the kill, you cocky bastard :p)



Follow this section accordingly, and I promise that you will ALWAYS win lane during Early Game.

So... now that you've picked up a few kills, have tons of cs (cuz, you know, you didn't miss ANY cs during laning, of course...) and have most of your core items, let the Mid Game commence! From here on out, your priorities change from cs'ing in lane to paying attention to your team. Whatever your team is doing, try and be there with them. Of course, there are exceptions such as every lane (mid, jung and bot) are at Dragon and the enemies don't have any Sight Wards. In a case SUCH AS that, stay top and farm some more. But if you're preparing to fight or need to control Dragon, head on down and help out; you do A LOT of damage. Just use your head, and everything will turn out great :)


!VERY IMPORTANT!


If you notice that your team is preparing for a team fight (such as: you're at an enemy tower getting ready to push it down), then you NEED to poke the enemy team. Jayce's poke is PHENOMENAL. All you do is (in cannon form) keep shooting your To the Skies! / Shock Blast through your Thundering Blow / Acceleration Gate. Prioritize the enemy squishies (their AD and AP carries are generally the two squishies) as your targets to hit. Following this build, that should do about 500-700 damage EVERY TIME it hits. That's an INSANE amount of damage. The object of poking them down is to get them low enough so that your chances of winning the team fight you're about to have are greatly increased (if not inevitable...) or so the enemy has to back-off from whatever objective you're trying to take, and you can safely obtain your gold :)

Team Fights (Mid/Late Game)

A good question that some of you might have been asking is: "So which weapon should I use during team fights?" Well, I'm here to give the answer! Based on what you've read so far about Jayce and his abilities, I hope that some of you are guessing or contemplating which weapon, cannon or hammer, is better in a fight. The answer: both! Confused? Let me explain...

There are different circumstances for both weapons, so I'll start with the cannon. Basically, YOU are the initiator for the team fights, so what better way to do so then with your Wombo-Combo! That's right, it's still packin' a punch! But, I'm getting ahead of myself... the combo is a bit different when used for an engage. So, it would start out by using your E Thundering Blow / Acceleration Gate then shooting your Q To the Skies! / Shock Blast through it (remember, you have the cannon out). "Who should I hit with the Q?" Well, everyone, of course! Just try and hit as many of the enemy team as you can with it; the more the merrier. Now that they're all missing ~250 hp or so, it's Hammer Time!

Go ahead and switch to your hammer, then proceed to find either the AD carry, or (whoever's doing better) either the AP mid or jungler.

NOTE: I'm assuming that your team is following up with you at this part, if they're not, then DO NOT engage with the hammer yet!

Now that you're ready to engage like a MAN, jump onto whoever you chose (using your Q To the Skies! / Shock Blast), activate your W Lightning Field / Hyper Charge and maul away at 'em! Remember that if it helps/if you're in position, knock (anyone) TOWARDS your team with your E Thundering Blow / Acceleration Gate! It also deals A LOT of damage once you start ranking it up (20% of their max health plus base damage plus 0.3 of your AD at rank 5.)

So, now we have the issue of stragglers. If your team didn't quite manage to secure all the kills, you have the toolset to mop-up, with ease, actually. All you have to do is chase them down (remember about your various move-speed buffs), whip out the cannon, and use your E+Q combo once more. If that doesn't finish them off, proceed with the wombo-combo :D

Late-Game and Mid-Game are basically the same... except you have to start worrying about the threats of your towers being pushed, inhibitors being destroyed, and baron being taken
