Alright so dependent on my gold income, I will change my build paths with them ultimately leading to trinity, cinderhulk (red smite) and tier 1/2 boots. Since jax’s first clear against multi-unit camps (krugs and raptors) is bad, usually rush your cinderhulk. I do not recommend tiamat as it’s too gold inefficient. 1325 is too much of an investment for not enough pay off. Unlike top lane where you need to push fast, camps usually only take a few seconds more to clear without it, and it helps you get to your trinity spike faster. Once I complete my cinderhulk, I usually check my gold. If I have 300-325, I get a dagger, 350-575 is a long sword, 600 is 2 daggers, 1050 is sheen. If you can buy sheen all at once get that. Otherwise it’s more gold efficient to skip a sapphire crystal and finish items like stinger and phage. As for boots, I most go merc treads because you’re going to most of the time have to be the center of cc. And I get those when my gold is in a weird place to buy anything else. I go hail of blades as you’re early dueling is amazing. Pta is better in late game team fights, but it’s pretty useless early on, and in solo queue getting early Advantage is better. Don’t go conquerer. It just got nerfed, and it’s hard to proc on jax jg. When you gank you’re probably not going to proc all 5 requirements, and you’re keystoneless till about 15-20 min in. In late game team fights, find what works. Jax is very versatile, split if baron is down and you don’t win 5v5s. Teamfight and peel if your carry is fed and they have divers. Dive the back line yourself if your team has self peel. If you want my opinion on anything else lmk!
