If you're ready to add a little versatility to your fighter or ranged carry game, look no further than Jayce, the Defender of Tomorrow. Jayce's transforming weapon allows him to adapt to nearly any situation, making him an extremely versatile champion for whatever role you need filled on the Fields of Justice.
The lynchpin in Jayce's kit is his ultimate. Starting with a free rank at Level 1, Jayce can activate his ultimate to transform his weapon into either the short range Mercury Hammer or the long range Mercury Cannon. Each time he transitions he'll receive a bonus effect on his next basic attack that either shreds the target's defensive stats ( ranged mode) or deals significantly increased damage ( melee mode).
Selecting the right weapon type for your current engagement is the key to playing Jayce effectively. While ranged, Jayce can pepper enemies with ranged attacks, deploying Shock Blast and Hyper Charge to wear down opponents while utilizing Acceleration Gate to keep his team at a safe distance. Having worn an enemy down in this manner, Acceleration Gate can be repurposed to give chase, allowing him to shift his weapon into its hammer form and leap into the fray with To The Skies!
Once he's closed the distance, he can utilize Thundering Blow to pick up a quick kill, while the additional Armor from being in melee mode gives him the toughness necessary to either withdraw or continue fighting at close range. However you choose to play Jayce, canny shifting between his weapon modes will make or break your success on the battlefield.

- Recommended Items
- Playing As Jayce
- Be sure to switch stances often. It will enhance your attacks and grant you quick bursts of speed.
- If you find yourself taking lots of damage, try using Jayce's Hammer Stance, as it grants you additional defenses.
- For increased range and damage, try casting Shock Blast through the Acceleration Gate.
- Playing Against Jayce
- Jayce can attack in melee or at range. Pay attention to his stance and weapon color to know how he is going to attack.
- If you see Jayce drop his Acceleration Gate, be careful, he is probably about to cast Shock Blast.
- Jayce is strong in the early game. If he gains the advantage, play defensively.
- Ability Usage
- Switching forms introduces an entirely new set of abilities that do not share the same cooldown with the abilities in the other set. Therefore, with no cooldown reduction Shock Blast has a cooldown of 8 seconds and switching forms has no effect on it.
- Switching forms, Lightning Field, Hyper Charge, and Acceleration Gate do not interrupt movement.
- Shock Blast's reveals the Fog of War and grants vision for a brief period.
- Casting Hyper Charge resets Jayce's autoattack timer.
- Acceleration Gate reveals fog of war at either end of the gate.
- The magic damage of Transform: Mercury Hammer is dealt to towers.
- Jayce has a great variety of abilities at his disposal. Judicious use of different combinations grants him excellent flexibility, able to adjust for most situations.
- Generally, Jayce stays in the Cannon Form to harass or poke the enemy with his ranged basic attacks and abilities. The Cannon Form is used for clearing waves and most importantly for bursting a target down.
- If you are in your Mercury Hammer form and need to quickly relocate, you can use your transform into the Mercury Cannon, giving you extra movement speed thanks to your passive and then immediately placing Acceleration Gate will give you a further significant speed boost.
- Additionally, casting Acceleration Gate, passing through it and then firing Shock Blast back through it will likely deal considerable damage to your pursuer, forcing him back or allowing you to finish him off with Hyper Charge and To the Skies! combo.
- Also, when firing Shock Blast through an Acceleration Gate, the range and damage on the Shock Blast is greatly increased allowing for high poking potential in the laning phase.
- Placing Jayce within the Acceleration Gate and casting Shock Blast won't tip off the enemy of the exact line you'll be firing on as much since the projectile of Shock Blast will be instantly speed up, giving them less time to better react. As well, casting Shock Blast and then placing Acceleration Gate in its path can allow it to hit an enemy that wrongly assumes they can out-run the ability.
- If you are being poked under your tower, quickly casting To the Skies! on a group of minions will clear them and damage your opponent. While they are slowed, you can use Thundering Blow to knock them back into tower range for a potential surprise kill.
- Thundering Blow has the capability to knock enemies over thin walls.
- Lightning Field can be very useful when trying to destroy minion waves and jungle camps.
- Lightning Field's passive allows easy mana recovery.
- When in Hammer Stance, To the Skies! makes an excellent gap closer, and grants the opportunity to unload deadly ability combinations.
- Hextech Capacitor's ability to ignore unit collision and increased movement speed can allow great positioning for singling out particular enemies, especially when they are attempting an escape.
- When an enemy is escaping, use Transform: Mercury Hammer to switch to Hammer Stance. Then, with the extra movement speed and the ability to ignore unit collision, move through the enemy until you are located in front of them. Then use Thundering Blow to knock them back. If they are too far away to catch with the movespeed alone, To the Skies! can be used as a gap closer, slowing them and even further disrupting an attempted escape.
- It is to be kept in mind that Jayce's Mercury Cannon has a much faster attack animation than his Mercury Hammer. This makes last hitting minions much easier to accomplish while ranged rather than as melee.
- As Acceleration Gate will also speed up allies in addition to yourself, casting it immediately in your team's path can help greatly when making a unified retreat or chase attempt.
- While in lane if against a melee champion, be sure to continually harass them while in your Mercury Cannon form, this will deny their minion kills and help give you more lane control. Doing this will inadvertently push up your lane so stay at a distance once you've pushed up to a tower in order to allow for an easy escape from a gank.
- If you know your enemy laner is not present, switch to your Mercury Hammer and restore mana.
- Item Usage
- Jayce can successfully be built as an AD carry or as an AD caster depending on his team's needs.
- Jayce, as he benefits at least moderately from all the stats it provides. He can proc spell blade regularly as he will be making repeated use of his spells and autoattacks in combat. is an useful item for
- Stacking attack speed on Jayce can be largely redundant as he already has a powerful attack speed steroid in the form of his Hyper Charge. Focusing instead on attack damage items can be more beneficial on him.
- Offensively, most of Jayce's damage is on the physical side, making armor penetration items very effective on him.
- Jayce's exceptional chasing abilities by slowing the opponent and making it extremely difficult to escape from him. It also grants a large amount of health, letting him stay in a fight for much longer. combines well with
- Cooldown reduction is a useful stat to itemize for on Jayce because of the utility and damage his spells afford him.
- The active effect of Acceleration Gate gives, allowing Jayce and his team to relocate extremely rapidly in an emergency. stacks well with the team-wide movement speed boost his
- Another great CDR item on Jayce is To the Skies! which gives him great wave clearing. This is a great build against a physical damage-heavy team as it gives 70 armor. . When combined with / , its AoE synergizes very well with
- Against a magic damage-heavy team, Jayce can opt to use either a or as sources of AD-focused magic resistance. A arguably benefits him more because of Hyper Charge's attack speed steroid and superior attack damage scaling, but by the same token Hyper Charge can also let him very quickly build the passive stacks on and offers higher magic resistance.
- Jayce when using Hyper Charge at max rank, as the enhanced attacks can critically strike. With an critical hits will deal 250% of his damage, and with a max ranked Hyper Charge, the enhanced attacks stack with critical strikes multiplicatively. This can ultimately result in up to three critical hits doing 275% damage. is an extremely powerful item on
- Thundering Blow and all three attacks of Hyper Charge. is a great item on Jayce. An early allows for longer sustain in lane and the toggle from procs on
- Jayce is highly vulnerable to ranged harass in lane due to his short autoattack range of 500 in cannon form, and most ranged attackers can reliably hit him without fear of return fire, as Jayce cannot benefit from the mana-gain-per-hit passive of Lightning Field without taking ranged harass should he run out of mana while in cannon form. Consider good poking top laners such as Kayle or Kennen to take advantage of this
- Although Jayce is very mana hungry, he is an AD ranged champion; he can just poke you with auto-attacks before going all-in with his abilities. As such it is not recommended to rely on Jayce going oom, as this will not happen against a smart Jayce.
- If Jayce is going mid, it is recommended to use a champion that can outrange him, such as Xerath, Ziggs, or Brand. They can poke Jayce from a safe distance and kite him, and they can push minions waves just as hard as him.
- A champion with a pet or clone can use it to block Jayce's Shock Blast if properly positioned. Champions who can do that are Malzahar (he also has a silence and a suppression which are detrimental to Jayce and can push the lane just as hard as him), Yorick (can outsustain Jayce), and Shaco (has no issues ganking Jayce).
- Although his poke in the form of Shock Blast is highly damaging, the projectile from this ability is slow and relatively easy to dodge. He can enhance the attack using his Acceleration Gate, but this makes his attack telegraphed, and lets you possibly enact countermeasures to it. You can also simply remain behind minions to block the shots. However, an accelerated Shock Blast has an AoE effect that can damage you through a line of minions.
- Despite his good mobility, Jayce only has one hard gap closer in the form of To the Skies!. Strong slows like Nasus's Wither can enormously reduce his effectiveness in combat.
- Most of Jayce's damage is physical. Buying early armor can help in mitigating his damage.
- Stacking health against Jayce is less effective as his Thundering Blow deals a large amount of magic damage based on your maximum health.
- When on the run from Jayce and his team, you can attempt unusual juking maneuvers in order to mess up his attempts to use Thundering Blow to knock you back towards his team.
- You may need different strategies to deal with Jayce depending on how he is playing.
- Jayce's ability to disrupt a team as a bruiser relies on the abilities of his Transform: Mercury Hammer and he must be in close range to do this. Knockback abilities like Tristana's Buster Shot and Alistar's Headbutt can quickly remove the threat he poses from a teamfight.
- Carry Jayce can put out considerable damage with his abilities in Transform: Mercury Cannon form, but the short range on his autoattacks means he must remain close to the front of a battle to make the most of his kit. This means he is highly vulnerable to attack from tanky champions such as Irelia or assassins like Akali. Even better, pulls such as Blitzcrank's Rocket Grab and Nautilus's Dredge Line when pulled off can yank him into range of your entire team and quickly burst him down before he can dish out significant damage.
- Jayce can use To the Skies! to cross walls and provide a surprise attack. Both denying him vision of key bushes by destroying any wards placed there and warding yourself to keep track of his movements will prevent him from abusing this.
- Since Jayce is not very sustainable, champions such as Cho'Gath, AP Nidalee, and Yorick would be able to out-sustain Jayce if they keep successfully harassing him. Building an item such as and starting with + 5 s can help out-sustain Jayce.
- In addition, because Thundering Blow has a long cooldown and it's his only disengage ability, you can use champions with double dashes such as Fiora, LeBlanc, and Renekton, and still be able to stick to him.
- As Jayce does not usually purchase critical chance and lifesteal items, he has poor sustained damage. Due to this, ADCs with mobility, such as Lucian and Vayne, should be able to take out Jayce easily as they outdamage him in straight up duels, as long as they dodge Jayce's abilities.
