Jayce is a top lane fighter. Jayce has 2 different forms (Ranged and Melee). His Mercury Cannon is his ranged form and his Mercury Hammer is his melee form. Each form has separate abilities meaning that he has 6 abilities available to him at level 3! Jayce is the definition of a lane bully. With his 6 abilities, he can poke, engage and kill the enemy champions. When you reach the late game with Jayce, you can use his poke to target the enemy carries and jump onto them to deal insane amounts of damage.
Jayce can also be played in the mid lane and jungle, make sure to check the alternative build at the top of the page! The build with Jayce mid lane and jungle is the same as Solo lane, there is not much else that is different in terms of play styles, build etc.
Transforming between the Mercury Hammer and Mercury Cannon grants bonus movement speed for just over a second. There is quite a long cooldown when switching between melee and ranged form so be careful!
Jayce leaps to an enemy, dealing physical damage and slowing nearby enemies for a few seconds. This is Jayce's gap-closing ability that allows him to jump on the backline easily.
This does however put you in a pretty dangerous spot to get focused and take a lot of damage so make sure you are wary of your surroundings before jumping in.
Jayce fires an orb that detonates on hitting an enemy or reaching the end of its path, dealing physical damage. This is Jayce's main poke ability that can be used to great effect in the laning phase and can be combo'd with Acceleration Gate (3rd Ability) so the orb can travel farther and faster, dealing increased damage.
This ability has 2 parts. A passive and an active. The passive is when Jayce is in Melee Form (Mercury Hammer) his attacks restore mana. The active releases an electrifying aura, dealing magic damage over a few seconds to nearby enemies.
This ability is best used just after To The Skies (1st Ability) as you will be on top of the enemy when you leap towards them so you can make the most out of the damage that Lighting Field brings.
Jayce gains a burst of energy, increasing Attack Speed for 3 attacks within a few seconds. This is best used when trying to poke doesn't the enemy as it does a lot of damage in such a short duration, but be careful as it doesn't have the biggest range so you can get caught out.
You can also use this ability when trying to push minion waves as quickly as possible so the enemy misses out on some experience and gold.
Jayce knocks a target and enemies near them backwards, dealing magic damage. Most of the time you want to save this ability and only use it to knock enemies away when you are in danger. However, you can also use this ability in combo with Flash to knock the enemy towards your team.
This is effective when the enemy carry is out of position, you can use To The Skies (1st Ability) to jump on top of the enemy and then use the Flash + Thundering Blow combo to knock the enemy carry into your team.
Jayce deploys an Acceleration Gate that grants decaying movement speed for a few seconds to yourself and ally champions that pass through it. This is very effective when you and the team are ready to engage.
You will all get a huge burst of movement speed that will not only help you but the rest of your team. You can combo Accelereration Gate with Shock Blase (1st Ability) dealing more damage and allowing Shock Blasts to travel farther and faster.
This is Jayce's ranged form. The next attack with the Mercury Cannon when transformed is empowered to deal additional magic damage and reduce the target's Armor and Magic Resist for a few seconds.
For most of the game, you want to stay in Ranged Form as long as possible because you can do a lot of poke damage not only in the laning phase but in team fights as well.
This is Jayce's Melee form. When transformed Jayce gains Attack Speed, Armor and Magic Resist. The next attack with the Mercury Hammer when transformed is empowered to deal additional magic damage.
Only use Mercury Hammer when you want to jump in and deal a lot of burst damage to the enemy champion.
Jayce uses a mixture of both damage and tank items that work well to help with his damage and keep him alive for longer. Hullbreaker is a great first item for Jayce. It gives him a lot of attack damage and Health and gives him resistances (more when in melee form) when he is by himself in the laning phase. Serylda's Grudge is another great item that helps Jayce deal damage and slow enemies with his abilities. This is really effective when in range form using his Acceleration Gate + Shock Blast combo.
For runes we have the following:
Jayce is a fighter so he wants to get in the enemies face and attack constantly. With Conqueror, Jayce can stack up pretty fast with all of his abilities and auto-attacks. Which means he can deal more damage and get a lot of physical vamp when fully stacked
With Jayce you will be in a lot of team fights jumping onto the backline trying to kill the enemy carries so dealing extra damage will always help and Jayce restores health every time he gets a takedown.
Nullifying Orb is a great rune that gives Jayce a shield that absorbs incoming damage when he drops low on health. This will help you survive that little bit longer so you can escape to safety or go in for the killing blow.
Demolish works well with champions that love to split push and build Hullbreaker like Jayce. It helps you push and destroy towers very quickly which can give you and your team a huge advantage.
Jayce is one of the best Early game champions in the Baron Lane. You want to play as aggressively as possible using both his Ranged and Melee forms to full effect. At level 3 you have 6 abilities available to you. When in ranged form, use Acceleration Gate and Shock Blast to poke down the enemy champion and when they get low enough, you can change to Melee form and use To The Skies to jump on top and deal the killing blow.
Once you get to the late game and Jayce has his core items, this is where you can become unstoppable with his poke and insane burst damage. When you are grouped with your team and about to have a teamfight, the best thing you want to do is poke down and jump onto the enemy backline where you can kill the main enemy carries. Always look at opportunities where you can change to your Melee form to jump in and burst the enemies to get an advantage for your team.
Overall Jayce is a very flexible and versatile champion that can be played in many different ways. It can be hard to play Jayce at first when there are so many abilities available but with a bit of practice you can pick him up and dominate your opponents.
