Start with a dorans shield for the extra defensive durability and health regen. Making u able to stay in lane longer early game. After that get mercury treads for the resistance. If the enemy team doesnt have that much cc, berserkers greaves is also ur second choice. After get ur shoes, u go for the lanturn giving u damage, durability and a free sight ward :D. Buying frozen mallet is the next step because of the massive health it gives, and the slow effect added to ur attacks. With a lot of hp now, you go for atma's impaler. The atma's is a great tank item since it adds armor and gives damage based on ur hp, which ull be buffing up with ur nxt two items: Warmogs and banshee's veil. ( Sell the Doran's shield to buy the banshee's veil ). After building to this tanky state, u want to go for some damage and life steal, so sell the wrigles lanturn for a final blood thirster :D

Getting the Damacian Standard is very important because of the armor and attack speed it passively gives. Start with getting all 3 of your spells then maxing ur damacian standard. (Ofc getting ur ult whenever u can) After maxing ur standard, I like to go for dragon strike. It is really up to u if u want the power and knock up from ur dragon strike, or if u want to go for the durability side. If the enemy team is rlly pushing u guys, go for ur golden aegis, but other than that, I suggest u go for Dragon Strike for damage. U max golden aegis last if u follow my build, because golden aegis is good enough at lvl 1 for the slow, so it is ok if u keep it there until late game.

I take a standard 9-21-0 for masteries. I reach the armor penatration in the offensive branch, and then go for all the dodge masteries in the defensive branch. This will make u able to break up ur enemies, while absorbing a bit of punishment.
