Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Threats to Jayce with this build
|Nidalee||AP Nid hasn't been strong for a while now and maybe she will never be again, I wouldn't worry about her unless she's jungling or is a Nidalee main.|
Jayce isn't the strongest champion right now and I believe he takes some skill to learn. He is still good in the right hands currently.
Armor penetration marks are good because of the current, but fading tank meta.
MR Glyphs Is for the AP champions you might be facing, if you're against a Zed take CD Glyphs.
Armor Seals are for if you're against an AD champion, if against AP take health seals.
AD Quints are for, well AD
Masteries are traditional caster ADC masteries with tenacity and some caster buffs for Jayce's caster nature.
Manamune is for loss of mana early and late game, and Jayce is very good at stacking it.
Ionian boots are for CDR and mana stacking.
Black Cleaver is for the ranged slow and for AD and the slightest bit of tankiness.
Banshees is so you don't get cc'd or you don't die as quickly, you could get GA or Scimitar for the same reason.
Last Whisper is for Armor Penetration because it will be fairly late by them and the tanks will have a lot of defensive items.
Bloodthirster is just for sustain and survivability
Barrier is good against assassins.
Ignite is good against poke champions that might take heal, (Xerath Ziggs etc.)
TP is good against all champions, or if you have very good map awareness.
Heal is good against assassins.
Jayce is a ranged AD caster that can be built as off-tank, poke or assassin, i prefer assassin which is what this build is above.
Jayce shines against squishy champions in the mid lane which is why I prefer to play him Mid>Top you will try to make the enemy poked down and hid under tower to provide pressure, try to roam once you have forced them under turret.
Pros / Cons
Pros: Good poke, strong lane, good defensive stats, very good for competitive play, Good Roams.
Cons: Almost worthless if behind, Weak against assassins
Creeping / Jungling
Getting a high creep score isn't difficult since you might as well use your abilities because you're going to want to use your abilities to stack your tear. And you have an empowered auto from your q. I would not recommend using your hammer stance to farm even though you get mana on every auto from hammer stance's w passive it's still dangerous because you can get harassed down to no health.
Jayce can put 6 points into every ability which makes him even more powerful late game.
