well hello there. that is my first guide on my favorite champion. sorry for my bad english here we start.

mastery

it really does not differ i like my mastrys 0/21/9 i think getting the spell smite is useless. but you can do what you like it wont effect the jungling.

skills

just get vitous strikes when ever it is there. that is pretty much it.

Runes

well these are my runes but it still does not matter in jungling.

Items

pretty basic attack items because tank Olaf is such a joke. tank Olaf basicly suck. you can also use your own build after getting the madred's razor then it is up to you.

HOW TO JUNGLE

that is what you were waiting for?
IT is really simple you start at the blue buff. sure you can take it. you ARE OLAF. start with the cloth armor and 5 potions. don't attack the small lizards first. get the big blue buffed golume first. you have to use smite on him while your vitous strike is active to gain HP. and you have to use a potion in the fight not after or you die.JUst use potions when ever needed but dont get max health keep it a bit low for your passives. if u know what i mean :D after blue i get the three wolfes then the four witched then the red buff. look for any posible ganks if you want. then get the 2 small golumes at the bottom of the map
After that get the others team blue buff or go back for your madred. just keep killing normal stuff until level 6 then you can take dragon out. no ultimate needed. just saying....
well keep on jungling in that routine kill dragon whenever it is alive try to keep a blue buff on. cover any on your mates lanes and gank strong ones. you should stop jungling at level 11 and start helping in pushing lanes. well that is it good luck and have FUN. ^^
hope you liked my guide and was help full.
