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.
I have seen many players that play Renekton play him as a squishy Meele dps. me on the other hand like to make him a bit beefy. After the patch came out that nerfed Cull of de meek ppl say it isnt worth it to buy Spirit visage well they are wrong pre patch i was able to tank 5 champions with cull of de meek and come out with more then 50% hp ... this just balanced it.
Now i start with Doran's shield like many players but i take Bruitalizer or Spirit visage first just depends on what u need or u like i perosnaly like to start on bruitaliser.
your goal erly game is to survive for i found renek to be rather weak erly game and collect the following items. Doran's shield, Ionian boots of Lucidity, Brutaliser and Spirit visage.
"Brutalier: this item is very good and it can be upgraded to even better item that gives speed boost it doesnt cost alot i my self just squise it some where in the build when i can buy it all in the same time."
Now in mid game u rarely get further then just Last wisper i rarely need to complete the build but i go with guardian angel next just because it adds that litle bit on top that makes this build so durable and follow up with Last wisper.
In late game it is up 2 you i either go with Infinity eadge, Frozen Mallet or Blood thirster. peronaly i like to go with Infinity eadge the only times i pick Frozen mallet is when the other team deals alot of dmg and i just need the durablity.
