I would say that you will be fine with 2 sort of build.
First build is against physical damage and second is against magical damage. These Items are something I like to use and if you find something that works better for you use them.
Against Physical damage:
So much sustain and safe from ganks!(Updated!)
(updated!)(not so good anymore)
if against hard physical lane (Rene,Darius, maby jayce)
I like to build couble dorans blade with every physical toplaner I play. It just makes you stronger with low cost
.If your stomping your lane, you can skip blades and go straight into bigger items.
Most important item:
This item is made for Jax. Nice slow, great synergy with passive. Really the core of Jax. This item is only offensive item you need to be able to stomp enemy carries
before or after
. Usually when you feel laning phase is ending and you need to start join fights, movement speed increase is necessary.
Get some armor or possibly mr if mid has gone out of hands.
is great armor item.
is always great item for tank.
is insanely good on Jax, against physical damage you get more ad the lower your health is, ad gives you armor. Also Jax's ult gives you mr, making the magic shield you get take more damage.
You can end your build with stacking more resistances. Also
is great last item ,because it costs a lot and you want your last item to be strongest item possible so gold wont go into waste.
Final Build against physical could look something like this:
Build against magical damage
This build is won't be much different from building against ad. You still want to build
as soon as possible.
So much sustain and safe from ganks!(Updated!)
. Good starting against magic damage and harass.(Updated!)
. Dorans blades are good for Jax. Blades help you get hp from harass and give you early kill potential.
Most important items:
is awesome item against ap. The shield you get, when you ult (ult gives you extra mr, making the shield stronger) will probably turn lost situation into your advantage. If your having trouble in lane, go
first. If you feel your dominating and lifesteal keeps you high health, go
. It makes you be able to kill the enemy. Get
when you feel laning phase is ending.
If enemy bot lane is stomping go
. If you feel that magic damage is only way you can die, go
the ultimate mr item for Jax. It gives you mr from ap and mr itself. You also have decent amount of magic damage yourself so 20mpen won't go into waste.
is good item, if you feel like the damage is balanced.
When you go into warmogs, you need to understand, that if enemy team has alot of lifestealer/spellvampers, you will be easy target for getting hp, because your getting flat hp.
If you go 1on1 with warmogs against ad carry, he can get lifesteal from you and survive until enemy team gets to help him. So don't go warmogs if enemy team is stacking lifesteal/spellvamp.
Final build against magic damage could look something like this:
Thoughts of other items
Jax can be build many ways and I just mentioned couble ways to build him.
There is a lot of situational items and I will mention few of them.
This is good item if you need to be the tank of the team and create slow to enemy bruisers so they won't get to your carries.
This is nice item. Because it gives alot of ap, I would use this against ap heavy team( it also gives armor, but enemy team always haves an ad carry). Slow is awesome if you can get enemy team stacked together.
This item is great when you are not the biggest threat of your team. All enemyes are diving onto your teams other key target. With this item you can just jump onto enemy ad carry and stomp him 1on1.
I quess you can build this item if jungler or support wont build it.
You could think this to be great item for Jax, but because Jax has e, the use of attack speed slow is not that great. You could build this instead of
If your team is like full ad, go this. It will be worth it if 4 people gets important stats from it.
If your hopelessly feeding and need damage to get minions cleared faster to be able to farm yourself back to game. Some like to use this item on champs that need push power. I think this is great for Olaf and Xin, but not that great for Jax.
This item is for more damage, instead of of tankyness. Get this item if you don't feel like you being the tank of the team. Also it's good to get some kind of slow like mallet or fist, to be able to stick your target, for better use of attack speed.
Hmm, never tried this one. But I heard that pro players have used this on streams. The stats it gives are ok against magic damage, but attack speed, its hard atribute to use on Jax. Well you can try this and tell how it went.
If you just need extra health, this is always nice choice for main tank. I just think my explanation of this item sucks earlier xD. And probably now xD. Don't stack hp with this item. Its a trap!! Even you get more hp5 from it, it makes you suck. You need to get armor,mr to make you take less damage, so your lifepoints are more stronger. that also makes you get more from hp/5.
It looks bad for Jax, If you need cc reduction, get
. But I haven't never even tried it. Someone just asked about it and thats why I wrote about this item.
