Going to need a leash on blue jungle is tough at the start but gets super easy right after you get your razors, just remember to gank top/bottom at level 2 right after you get blue and heal up with your health pots... Gotta get fed fast

Passive explains the need for the movement speed items at the start, obviously trinity is just to good with phage and sheen effects on it, the attack speed is actually amazing on this champ...Skill sequence, your W has a max effect on minion's therefore I dont find it as necessary in the jungle as it is in lane.

Ghost obviously again necessary with the passive and E bonus' super overpowered, smite you're jungling gonna need it.

All in all, never failed to go legendary with this build as long as you play smart and support your team a lot.
