General Tips and Tricks

  • 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.png Shock Blast has a cooldown of 8 seconds and switching forms has no effect on it.
  • Switching forms, Lightning Field.png Lightning Field,Hyper Charge.png Hyper Charge, Acceleration Gate.png Acceleration Gate do not interrupt movement.

Shock Blast

Hyper Charge

  • Casting Hyper Charge.png Hyper Charge resets the auto attack timer.
  • With the AA reset and the attack speed bonus it is possible to clear stealth wards before they stealth.
  • The attack speed bonus and the auto attack modifier of Hyper Charge.png Hyper Charge is not lost after transforming. The magic damage of Transform- Mercury Hammer.png Transform: Mercury Hammer is not affected by the modifier, however.

Acceleration Gate

Transform: Mercury Hammer


  • Jayce 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 Jayce stays in the Transform- Mercury Cannon.png Cannon Form to harass or poke the enemy with his ranged basic attacks and abilities. The Transform- Mercury Cannon.png Cannon Form is used for clearing waves and most importantly for bursting a target down.
  • If you are in yourTransform- Mercury Hammer.png Mercury Hammer form and need to quickly relocate, you can use your transform into the Transform- Mercury Cannon.png Mercury Cannon, giving you extra movement speed thanks to your passive and then immediately placing Acceleration Gate.png Acceleration Gate will give you a further significant speed boost.
    • Additionally, casting Acceleration Gate.png Acceleration Gate, passing through it and then firing Shock Blast.png 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.png Hyper Charge and To the Skies!.png To the Skies! combo.
    • Also, when firing Shock Blast.png Shock Blast through an Acceleration Gate.png Acceleration Gate, the range and damage on the Shock Blast.png Shock Blast is greatly increased allowing for high poking potential in the laning phase.
      • Placing Jayce Jayce within the Acceleration Gate.png Acceleration Gate and casting Shock Blast.png 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.png Shock Blast will be instantly speed up, giving them less time to better react. As well, casting Shock Blast.png Shock Blast and then placing Acceleration Gate.png 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!.png To the Skies! on a group of minions will clear them and damage your opponent. While they are slowed, you can use Thundering Blow.png Thundering Blow to knock them back into tower range for a potential surprise kill.
  • Thundering Blow.png Thundering Blow has the capability to knock enemies over thin walls.
  • Lightning Field.png Lightning Field can be very useful when trying to destroy minion waves and jungle camps.
  • When in Transform- Mercury Hammer.png Hammer Stance, To the Skies!.png To the Skies! makes an excellent gap closer, and grants the opportunity to unload deadly ability combinations.
  • Hextech Capacitor.png 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.png Transform: Mercury Hammer to switch to Transform- Mercury Hammer.png 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.png Thundering Blow to knock them back. If they are too far away to catch with the movespeed alone, To the Skies!.png 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 Jayce's Transform- Mercury Cannon.png Mercury Cannon has a much faster attack animation than his Transform- Mercury Hammer.png Mercury Hammer. This makes last hitting minions much easier to accomplish while ranged rather than as melee.
  • As Acceleration Gate.png 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 Transform- Mercury Cannon.png 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 Transform- Mercury Hammer.png Mercury Hammer and restore mana.

  • Jayce Jayce is highly vulnerable to ranged harass in lane due to his short autoattack range of 500 in Transform- Mercury Cannon.png cannon form, and most ranged attackers can reliably hit him without fear of return fire, as Jayce Jayce cannot benefit from the mana-gain-per-hit passive of Lightning Field.png Lightning Field without taking ranged harass should he run out of mana while in Transform- Mercury Cannon.png cannon form. Consider good poking top laners such as Kayle Kayle or Kennen 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 Jayce is going mid, it is recommended to use a champion that can outrange him, such as Xerath Xerath, Ziggs Ziggs, or Brand 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.png Shock Blast if properly positioned. Champions who can do that are Malzahar 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 Yorick (can outsustain Jayce), and Shaco Shaco (has no issues ganking Jayce).
  • Although his poke in the form of Shock Blast.png 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.png 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.png Shock Blast has an AoE effect that can damage you through a line of minions.
  • Despite his good mobility, Jayce Jayce only has one hard gap closer in the form of To the Skies!.png To the Skies!. Strong slows like Nasus Nasus's Wither.png Wither can enormously reduce his effectiveness in combat.
    • To the Skies!.png To the Skies!, even though it is a targeted ability, does not actually track enemies who are moving. A blink or dash ability used while he is in flight can dodge his attack and avoid his slow. You should try to save these escapes for when he is about to use it.
  • Most of Jayce Jayce's damage is physical. Buying early armor can help in mitigating his damage.
  • Stacking health against Jayce Jayce is less effective as his Thundering Blow.png Thundering Blow deals a large amount of magic damage based on your maximum health.
  • When on the run from Jayce Jayce and his team, you can attempt unusual juking maneuvers in order to mess up his attempts to use Thundering Blow.png Thundering Blow to knock you back towards his team.
  • You may need different strategies to deal with Jayce Jayce depending on how he is playing.
    • Jayce Jayce's ability to disrupt a team as a bruiser relies on the abilities of his Transform- Mercury Hammer.png Transform: Mercury Hammer and he must be in close range to do this. Knockback abilities like Tristana Tristana's Buster Shot.png Buster Shot and Alistar Alistar's Headbutt.png Headbutt can quickly remove the threat he poses from a teamfight.
    • Carry Jayce Jayce can put out considerable damage with his abilities in Transform- Mercury Cannon.png 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 Irelia or assassins like Akali Akali. Even better, pulls such as Blitzcrank Blitzcrank's Rocket Grab.png Rocket Grab and Nautilus Nautilus's Dredge Line.png 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 Jayce can use To the Skies!.png 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 Jayce is not very sustainable, champions such as Cho&#039;Gath Cho'Gath, AP Nidalee Nidalee, and Yorick Yorick would be able to out-sustain Jayce Jayce if they keep successfully harassing him. Building an item such as Chain Vest item.png Chain Vest and starting with a Cloth Armor item.png Cloth Armor and 5 Health Potion item.png Health Potions can help out-sustain Jayce Jayce.
  • In addition, because Thundering Blow.png Thundering Blow has a long cooldown and it's his only disengage ability, you can use champions with double dashes such as Fiora Fiora, LeBlanc LeBlanc, and Renekton 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 Lucian and Vayne 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.
