This is my first time making a build on a website so any commentary or criticism is welcome I made a Riven jungler because she is an awesome character and her Valor to Ki Burst combo helps with ganks a lot.

Marks Attack Damage because all of he abilities revolve around Attack Damage and a little more attack damage at the beginning while jungling and ganking is always a good thing.

Seals Armor because while jungling the monsters only hit you with physical attacks so a little armor doesnt hurt.

Quints and Glyphs Attack speed because every jungler needs a little attack speed and it works well to have it from the beginning.

Well smite for the obvious reason XD
I chose ignite as the secondary spell because everyone tends to run at low health and having ignite to finish them off isn't so bad is it.

I start off with Cloth Armor and 5 Health Potions so that i have a little sustain while jungling and dont have to come back to base until i have at least 1000 Gold or more to buy Boots and Vampiric Scepter. I start off with the wraiths using a normal attack to start and the using Broken wings in between every attack i hit a normal to use her Passive ability then for Red buff then the small golems and by the time im done with the golems the wraiths respawn and i can go kill em again. Then work my way through wolves and blue buff and by the time im done with a 3rd wraiths kill you should be at level 4 so gank away.
