There are several. 9 means smite b -means recall buy upgrade and/or pot n boots
As a jung main you want to take different routes for different champ types.
My path... the best for most- gromp 9, blue, wolves, red 9 , raptors, krugs
For great clearing champs. - Start krug 9, red, raptors, blue, gromp and wolves then b.
For snowbally devour types. - krugs 9, raptors, wolves gromp b then buffs and a scut.
for bad clear champs. - gromp 9, blue, wolves b... then krugs9, red, raptors
for assassin jungs- krugs 9, red, blue then look for gank.
typically you want to look for a cheeze level 3 gank and gank immediately at 6 if you have a decent chance at a kill.
So much to learn and do as a jung thats why I love it. I also recommend
and the blue smite
item.
Add me if you want and i can show you the ropes a bit. Good luck and have fun
