Hello...I enjoy to play Jayce and I need a fighter or tanky build for him for when I am behind and I cant afford too many damage items or if my teammates are too squishy. So, can you give me some build examples that work well on Jayce? Keep in mind that I need to cover at least 30% cdr and mana :D
Ralanr1 votesFrozen heart would be a decent item for the job then.
Sahn Uzal1 votesJayce does really like his 
though, doens't he?
Ralanr1 votesWell yeah and nothing stops him from getting both and maxing out his CDR.
Sahn Uzal1 votesThat's fair. Didn't really consider it because I have 10% cdr in almost all of my runepages :P
Ralanr1 votesI don't use CDR runes because they mess with my CDR builds in game (except when I played pantheon). There is enough CDR in game that I don't need to worry.
Instead I go for simple set ups of offensive reds (AP, magic pen, or AD reds), defensive yellows and blues (AD and MR) and specialized quints (Hybrid pen, AD, or AP).
EndlessSorcerer1 votesIt depends on the champions and what I want to build.
I never bother with CDR runes on Jayce since I will generally be fighting early (so I need MR in mid-lane) and my core items provide 40% CDR anyways (Ionian Boots, Muramana, Youmuu's Ghostblade, Black Cleaver).
However, certain champions are generally safe enough that they don't need MR and don't want to build certain items for it.
I generally take 20% scaling CDR on long-range champions such as Lux and Varus since I generally won't be fighting early-game (instead trying to farm for the mid-game). As such, I can generally cap my CDR with one or two core items:
That said, I have 20 rune pages and pretty much every useful rune so I have plenty of flexibility in my set-ups.
EndlessSorcerer1 votesI have only recently gotten into Jayce, but you could probably get away with something like:
Ladrac1 votesLooks good, but for my preference I will edit and it will look like this:
I dont really like to build 
...anyway, thank you, your example build inspired me :3
