This is my first guide to mobafire, so i'm able to receive any suggestion or critic from you guys. Thanks for Read.
Jayce is a champion that you need some skill to play due to his skill variability, with practice you can do with him what you never did with another champion before, he is a very strong champion.
Pros / Cons
Funny to play;
Very much help for the team;
Need Sniper skills.
Runes and Masteries
About runes I ever build him with attack damage marks and quints for maximize Jayce's early game (farm and harass). Defense and Magical Resist per level cause I think that this is better than put ad runes on seals and glyphs. Nothing more to say here.
About his masteries, I guess that almost every ad ranged dps use that way (21/9/0).
AD, attack speed, lifesteal, a little bit of armor pen and thats it.
Lets priorize his damage since the beggining, attack speed isnt that important cause you do a large damage with To The Skies! + Thundering Blow combo and/or Shock Blast + Acceleration Gate, so, do AD.
Start with boot + potions is more safe than start with one Doran Blade, but if u wanna play agressive and/or your support is your friend, I ever buy boot + potions.
Buy one Doran Blade if ur early game start very bad, after, buy one B. F. Sword for ur AD up a lot. Then rush your Berseker's Greaves and your The Bloodthirster. After it, start your Trinity Forcewith Sheen then Phage, and do quickly one Infinity Edge for maximize your criticals.
You can buy another The Bloothirster and the last item can be from your own necessity, like Phantom Dancer, Guardian Angel and others.
Obsevation: I never played a game that I could buy more than 4 full items, they over quickly if you do your job.
Flash and Heal for Sustain and for surprise your enemy when he is trying to kill you.
Another spells makes Jayce very squishy.
Ignite and Exhaust can be used against some especific champions, like ignite for voli/swain.
My build as solo top is a little bit tanker than the ad bot build, because almost all solo tops must be "tankers" on game.
Very important item for off tankers, tenacity+movespeed+magic resist.
Gives you ad, magic resist, more ad when you are at low hp, and one good spell shield.
More hp, armor, a little cooldown reduction and it able you to escape or start team fights.
At early game you need to farm as much as you can, last hiting minions and shoting enemy champions when the oportunity comes.
Start to combo Acceleration Gate + Shock Blast when you reach level 3 (when Shock Blast is lvl 2) for harass and To The Skies! can be used for farm. At mid game ur combos will kill the minions waves easily.
Jayce is a very versatile champion, if you know how to build and use him, your team will be very pleased with all your assist.
My actual scores as Jayce:
