Hello Guys, my name is Dom1nus and i am a Renekton One Trick Pony. Peak Rank 3 Renekton and micro wise i have perfected this champion, hope this guide helps.
If yoy would like cheap personal coaching sessions vod reviews and in depth renekton guide about not only Renekton, but for a wide variety of top laners, feel free to dm me !

Renekton is a fun Lane Bully, he has hard snowball abilities and he is easy to learn while maintaining a high skill ceiling. He has mobility, single un-avoideable stun nuke, good sustain while providing Aoe damage. Unlike most of the champions renekton doesnt have mana, he has fury and prorer management of fury divides bad, good and God Renekton players.

Renekton has a weak Lvl 1 and Lvl 2, what i like is having lane priority so i want my jungler to start bot side, i push the first wave in trade with the opponent auto q so he can poked down and push the minions. At level 2 where u unlock e u can: e q auto e thats called the panther combo. After u see that the opponent has 50% hp or less get ur fury to 50% and e > Auto > W > Auto again as when u emp w he gets stunned for 1.5 secs and u get stunned for 0.75, so u have a small window for another auto, then finish with q and e to him again if needed. i like to take ignite so i can win my lane,and later win the game.

Renekton shines in Mid Game, if u have ur core items look for drake plays, catch targets that are alone and force 5v4s. Push towers get a gold advantage so u can end the game as early as possible. If u have a tank or someone with a hook/stun that can engage let him do the first move and after him u should engage and prioritize the most fed squishy target. either it is their mid, their adc or their SQUISHY jungler ( for the love of god dont focus the full tank WarWick). U will never have a problem facing a fed top laner as u have dominated the lane and he still tries to finish up his first item.IF u lost lane hard, and u are quite behind dont look to go in unless u can pick off targets with low hp, Instead stay next to ur adc or mid lane carry and peel for them(protect them from dying).

If the game goes this late, that means ur team is trash and the game is over anyways. Nah, just be careful and ward a LOT, they will try to play around baron when he is up and look for the bushes in case they try to trap(buy the blue ward so u can ward safely) dont be greedy and go for their squishy carry, do 5v5 fights or try to catch someone off and force 5v4 team fight or get baron. If u have a crazy fed adc and because rene falls of late game, it would be better to peel her and let her win you the game. If the opponent team have a soraka lulu or janna, go for them instead as they can cause a lot of trouble.
