people might think this is a troll build but it is not. Jungle gp is viable for ranked and works very well and in my personal opinion he has one of the best jungle ganking in the game since the recent buffs.

edit: i also wanted to make a lane gp build as well because if you take a solo lane with him even mid u should do good.

These are standard jungle masteries. Some may wonder why i use good hands and thats because the other option is not that good.

I use standard jungle runes. Armor pen reds, armor seals, flat cdr blues, 1 armor pen quint and 2 health quints. One thing to not it is very important to get the 2 health quints i dont even know id it works without it.

I start at blue and if u do start at blue u need leash and some help so u don't lose to much hp, than go to wolfs, wraiths and red buff, and after this decide to go gank, or get double golem, or b.

edit: recently i stared with life steal went wolfs, wraiths golems, recall. get cloth armor health pot get blue, other jungle stuff and red, than gank. it explains it pretty well in this video from stonewall.

This subject can be tricky, u need patience to do this right. Make sure there is no wards (asking teammate/oracle) and go in when u can get parley red buff and start auto attacking for slows and dmg.

standard spells

This is tricky, well u want to focus carries but u do not wanna overextend and get focused yourself.

Don't down vote till you try the build with the right runes and masteries.
thx u for reading, and have fun jungling.
