Hello, and welcome to my first guide on MOBAFire. I decided to make this guide because I felt that Jayce was--as of the time this guide was made--a fairly underestimated champion. Most people don't seem to understand how Jayce can be played to his full potential. This isn't to say that I am the best Jayce player, or that any of the other guides are worse than mine. For the longest time, I've used the Jazzy Jayce build guide, and I still like it, but I felt that there were flaws in it, and I wanted to add my own input to the Jayce build guides.

Quick little note: My original intention was to finish the revamp before releasing it, but I figured I may as well let you guys know that I'm doing one.

Pros / Cons

  • Versatile.
  • Good AD scaling.
  • Consistent throughout game.
  • Not easily countered.
  • Has a Space Marine/James Bond skin.
  • Short range.
  • Squishy early game.
  • Mana starved throughout the game.
  • High skill cap.
  • People don't think he's viable.

I decided to run 21/9/0 on Jayce. Jayce is a powerful champion, and benefits a lot of AD. In the same way, he needs a bit of cooldown reduction, which can attained through the Sorcery perk. Executioner is a great perk, as it can net you kills with a well placed Shock Blast into Acceleration Gate on a low-health enemy. Even with his considerable offense, Jayce does need defense, so points go into that tree for early health and resistances.

Offense Tree

Tier 1 - 4 points go into Fury for more DPS and extra farming. Summoner's Wrath because it beefs up Ignite and Exhaust (which I find myself getting more and more often). 2 points go into Sorcery for a little bit of CDR.

Tier 2 - 4 points go into Deadliness for extra AD; better scaling and farming.

Tier 3 - 3 points into Havoc for increase damage all around, 1 into Weapon Expertise for sorely needed passive armor penetration.

Tier 4 - Pumps a little more AD into Jayce, increases damage on Shock Blast.

Tier 5 - The flat penetration is nice, but it more leads into Executioner than anything else. Awesome for clutch Shock Blast + Acceleration Gates.

Tier 6 - More damage to low-health targets and minions from all sources.

Defense Tree

Tier 1 - All 4 points go into Durability for extra mid-late game health and survivability.

Tier 2 - 2 points into Hardiness to stave off minion damage in lane and jungle while and 2 go into Resistance for any magic damage you might encounter..

Tier 3 - Veteran's Scars gives more flat health in the early game.

Greater Mark of Attack Damage

Greater Seal of Armor

Greater Glyph of Scaling Magic Resist

Greater Quintessence of Attack Damage

Greater Quintessence of Attack Damage/ Greater Mark of Attack Damage for better scaling on abilities, as well as easier last-hitting and harass in lane. Also makes early lifesteal more effective.

Greater Seal of Armor gives Jayce the ability to stave damage from most top laners.

Greater Glyph of Scaling Magic Resist for lategame MR, as most AP casters will have stronger lategames. They also help against those solo tops like Akali or Fizz, who deal magic damage.

Summoner Spells

Ignite is a great spell on Jayce. The point in Summoner's Wrath gives you some AD and AP while it's down, and can net you kills you might not get otherwise. Shock Blast is great at doing that, but can be unreliable and frustrating if you're not used to it, or just not that great at skillshots. Ignite is a guaranteed 410 true damage at level 18, and it reduces healing for that pesky lifesteal and Sorakas. In short, Ignite offers decent utility can can net you kills early. Flash is probably one of the best spells in the game, especially someone as prone to CC as Jayce. Given that Jayce does have great escapes through Acceleration Gate and Hextech Capacitor, it seems a little redundant to get another escape tool. The advantage to Flash is this: it removes you from the map for a split second and puts you back out of harms way if used creatively. That split-second can save your life, too. You can dodge skillshots that would otherwise hit you.

Obviously there are other good spells, Teleport, Exhaust, and Barrier are among the ones I get most, and perhaps the best ones for Jayce. They're not preferred, though. Barrier is a spell that should be picked against someone like Tryndamere or Malphite, champions who can withstand or otherwise tank the turret's damage. If you do find yourself against someone like that, Jayce probably isn't the best choice against them. Teleport is a great spell, but has an obnoxious cooldown and should only be taken if you need more map presence and your team wards a lot. Exhaust is the best among these spells: most teams won't get it besides the support and/or jungler (and depending on your jungler you might get Flash or Ghost), and the point in Summoner's Wrath increases the slow and decreases the target's damage, armor, and magic resist.

Skill Break-Down

(Passive) - Hextech Capacitor

Upon using either Transform: Mercury Hammer/ Mercury Cannon, Jayce gains a flat amount of movement speed and can pass through units for 1.75 seconds.

Spoiler: Click to view

(Q) - To the Skies/Shock Blast

To The Skies! sends Jayce to a targeted enemy unit, where he crashes down, dealing physical damage and slowing in an area. Shock Blast sends a skill shot nuke in a line towards a location, dealing physical damage. The effect of Shock Blast is greatly increased when fired through Acceleration Gate.

Spoiler: Click to view

(W) - Lightning Field/Hyper Charge

Lightning Field restores mana on hit in Mercury Hammer form and deals magic damage in an area aorund Jayce over four seconds. Hyper Charge resets the autoattack timer and raises Jayce's attack speed to the hard cap for the next three autoattacks.

Spoiler: Click to view

(E) - Thundering Blow/Acceleration Gate

Thundering Blow knocks back target enemy champion and deals damage based on their maximum health Acceleration Gate summons a zone that speeds up allied champions and greatly increase Shock Blast's effectiveness.

Spoiler: Click to view

(R) - Transform: Mercury Cannon/Transform: Mercury Hammer

Transform: Mercury Cannon switches Jayce into his ranged form, giving him different abilities and causing his next autoattack to shred the enemy's armor and magic resist. Transform: Mercury Hammer switches Jayce into his melee form, giving him different abilities and extra armor and magic resist. Jayce's first autoattack deals bonus magic damage.

: Finally, after so fricking long, Riot decided to give us an item dedicated to AD Casters. The armor shred on this thing is amazing, and it builds from The Brutalizer. I honestly can't think of a better item on Jayce. It's that amazing.

: I've been playing Jayce a little more, and upon looking at Muramana, I decided to replace Trinity Force here with Muramana. Muramana offers a nice active that procs on Shock Blast, making it deal rough 500-600 damage with the Acceleration Gate multiplier. It also increases his Hammer Stance damage in a way that Ravenous Hydra couldn't. Muramana is also reliable, in that you will always land auto attacks and spells like Thundering Blow and To The Skies!, both of which proc Muramana's toggle.

: 1000 health. Since Jayce gets some resistances through his Mercury Hammer, he doesn't really need to build those, but he has a low-ish amount of health (2040) without items at level 18. Health means living longer, and Jayce is a short-ranged carry, and he needs to be alive to get his damage out.

: This is another great item. It gives some nice MR mid-game, and since most casters are going to be mid-late game champions, these should be built as soon as possible if their AP is doing anything, which will be most of the time. The Tenacity also makes me buy these more often than not; Jayce is devastated by hard CC's.

: These are your third wheel boots. You almost never get them, unless their team is Master Yi, Tryndamere, Fiora, Master Yi, and Master Yi. They're alright, but Mercury's Treads usually wins out. Again, only get these unless their AD is a problem, or if you don't want to get your Tenacity through Merc Treads.

: Jayce has great synergy with high movement speed items because he has a very nice slew of speed bonuses. The slow resistance on these boots is great, as Jayce's escapes all rely on movement speed, and it reduces the power that slows have over in situations where he needs to get away. Get these boots if their team is filled with slows, and you need to be moving around a lot.

: Since the Season 3 update, this item has lost favor for me. I like the changes that were made to it, but I still think there are better options. Nonetheless, it's still here because it is a good item when you're getting a lot of kills and you want TONS OF DAMAGE.

: Trinity Force is the bread and butter of burst fighters. It literally has everything. I like getting Trinity Force on Jayce when I'm ahead and doing well. It gives a splash of utility as well as durability, and it gives a load of offensive buffs, chief among those being the Spellblade passive.

: This item has replaced Atma's Impaler on this guide. Atma's simply doesn't do its job anymore, especially since Warmog's is no longer core. I like Last Whisper over Atma's because of the percent armor penetration, and flat AD is never a bad thing. Get it against armor stackers like Malphite.

: Otherwise known as Madred's Bloodrazor 2.0 (moment of silence, please). Despite my missing Madred's, I am a little bit happier with this item than Madred's. I like that the on-hit effect deals physical damage, so Armor Penetration is a little more viable with it, and it has a nice active with attack speed and lifesteal, so it fits in that little niche of damage/sustain hybrids. A good item that is very underrated right now, get it if their team is stacking health.

: I've been in love with Warmog's Armor for a really long time, and it adds a brilliant amount of beefiness to your champion. With the rise of Blade of the Ruined King, though, health has become a little less effective, but Warmog's is still viable on Jayce.

: I cannot tell how many times I've been saved by this thing (not necessarily on Jayce, either). The passive is great, and the Armor and MR bonuses are great. This is a great item when you're backdooring or you just need to keep fighting/running longer.

: Randuin's is also a great item that I see becoming very popular in the near future. The Cold Steel passive is great for slowing down the enemy carry, especially if it isn't a carry that builds tons of attack speed (i.e. Jayce, Ezreal). The armor and health are great bonus, and the active allows for Jayce to have a great follow-up initiate.

: Another item to get when the AP is trouble. Again, this is a nice item because it offers good damage, but this item is more for the Quicksilver Sash passive. Get this when you need MR and you're getting CC'd a ton. I recommend this over Banshee's Veil if you need survivability and damage.

So, time for the end. It's been a good run, and it's been fun creating this thing, and I hope you enjoy this guide. I just want to make clear that this isn't the RIGHT way to play Jayce. This is simply the way I play him. I have borrowed some ideas from both Jazzy Jayce and The Superhero's Guide to Jayce, the two top guides on MOBAFire. I will link them in the section below. Thanks so much for reading and bearing with me, and if you liked it, leave a comment and a rating, and if you didn't leave a comment and a rating. I'll accept any criticism you guys can offer, but I won't respond to trolls or spammers. I want good, honest people critiquing my work, not trolls and jerks. And again, thanks for reading.
