Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
So this is my post nerf jungling plan for Olaf still tweaking it around but standard jungling approach basically just changes due to the massive nerf of Vicious strikes havent extensively tested it yet but feel free to comment and give feedback ill update as things work/don't work
With the changes Undertow seems to have become much more viable to the point that it may work to go between undertow and reckless swing for skilling up maybe alternate maybe a few more points in undertow or reckless swing as is seen fit but like i said still tweakin it so here goes to battle!
so updatin put in the force of nature to replace ghostblade its just too expensive and hard to get before the games over also if your not having survivability issues go straight for upgrading zeal for phantom dancer get out more dps common sense stuff gotta be flexible or you break.
