-look what the enemie team got for ap better get an Quicksilver Sash
-and for an ad team with 3 ads or more use thornmail insteat of sunfire u need life later

-you are a jungler so you realy NEED smite even after the new masteries!!!
-flash is a very good spell aswell, just if you are ganking or in late game you could falsh onto a focused enemie and taunt him
-ghost :not use it if youre gankin a minion wave stops you and if youre in fight youre also not fast enough so DONT take it

-for runes use life Quintessences cause in early you must have enough life cause you could gank well with it
-you need armor for jungle and ad
-also not only armor help you to tank so you need a little bit mr
-you also need lifereg because you could stay longer in the jungle

-you need only one point in powerball skill it on level 2
-max taunt first
-second your shield (easy tower dive)
-and of curse skill ult on lv 6,11 and 16

Normal road:
-start at the golems not(blue) then you get lv 2 and could skill shield
-run to the wraiths and go in the mid of them then powerball and shield
-after this dont waste mana kill wolves with heal potions and auto hits
-after that go blue with q -> w,w,w,w,w.... gank bot/top then

alternative gank mid after wraiths if you see a low life champ there

Second road:
-start at blue with w
-powerball the wolves,w
-wraiths
-gank mid or go golems then gank top

-youre the tank so you must go in first (do this easily with q)
-try to taunt the ad carry or one with low health(more easy with flash)
-after this use ult and w

-Rammus is a very good ganker just stand in a brush and start q then wait a few seconds cause you get faster and faster
-after this taunt (ult if you got)

-other method is if you run behind an enemie taunt him then powerball him to your mates then w and r
