Well, hello there! I'm low elo player, so gold it is... I found this build doing well, so you can try it if you want. And btw sry because of my english :)

For runes I think this rune page is good. You gain that ats for clear and armor for sustain, i pick mr blues because you wont build any other mr item except spirit visage, but cdr blues are fine too. Reds are for attack damage, and that is only dmg you will have lol :D

Currently the best masteries for jungle you can find, i use it on every jungler i play, because that bonus health and heal when clear camp is so good. You can go 12/0/18, but i think this one (0/12/18) is better because you get that 15% longer buff duration, and movement speed out of combat is good too..

Classic start, but i decided that Tracker's Knife is better than Stalker's Blade, because you don't need that slow, and on the other hand vision is great. GA is very important for you, because you will be that engage your team need, and with GA, your team will manage to save you and win the fight. For boots you can go swifties, but Mercury's treads are good too. When is time to pick your last item you can decide if you want Sterak's, or Randuin's, with Sterak you will get that shield and dmg, but Randuin's will give you that less dmg from critical attacks, i prefer Randuin's, its so much better in my opinion.

Pros :
- good clear with that Bami's
- you can easily dive early
- your ganks are stronger now when you can tank dmg for long time
- on some hand he win against Kha'zix with this build
Cons :
- you don't have damage at all
- you need to escape fights early on so you can be strong later
- without red buff at early game, you are useless
- when you are against jungler with Skirmisher's Sabre, you lose 95%
- you kinda depend on your E skill shot, so if you can't hit it will be bad af

Your jungling at the begin is so bad, you will probably need to use W on top side of jungle just to get that heal, you need strong leash from your bottom lane so you can get all your jungle creeps in one tour. But when you get your Bami's Cinder, your creeping is so easy, with that item you can easily go to enemy's jungle and farm as long as you can, because they can't do sh*t to you then. Jungling with your Tracker's Cinderhulk will be as same as with warrior.

In team fights you are BEAST! When you get in with your 5 stacks ult and hit E on their carry, it's priceless how they panic, because you dive in 5 people and they can't kill you. In TF you will only go for their carry, no one else, or Soraka if they have one in team. Your GA will do the thing if your team didn't manage to came on time.
