Hi, my name is Hord, Gold Elo Renekton main.

In this guide i will be trying to share with you everything i have experienced with Renekton over the past few months i played him.

[P] Passive

It let's you stack fury, wich lets you use empowered version of your basic ability.

[Q] Cull the Meek

Cull the Meek is an AoE, AD scaling spell, that heals you based on how much enemies have you hit.
Empowered [Q] – Gets you more heal (up to 600) and some extra damage.

[W] Ruthless Predator

Ruthless Predator gives your next AA 0.75 Sec. stun and some bonus damage.
Empowered – 1.5 Sec. stun and more damage, also removes target's shields befor any other effects of this ability. You are almost always looking to Empower due to the benefits you get from Empowered [W] are way better than any other Empowered abilities.

[E] Slice & Dice

Slice is Gap Closer, you can use it to engage, disengage or for short trades. It deals AD damage.

Dice is a little bit tricky. In order to use Dice you have to hit an enemy with your Slice. Dice is also Gap Closer, you usually use it to disengage from Trades.
Empowered [E] – Deals some extra damage,lower's the target's armor, you almost never want to have Empowered [E] if possible.

[R] Dominus

On activates, Dominus empowers you for 15 seconds, giving you bonus health (250/500/750) and 20 Fury. For the duration you deal AP Damage each half of a second to enemies nearby and generates 5 Fury per second.

Pre-lvl 3 you are really Weak, when you reach lvl 3y you become really powerful, due to the fact you have your full combo unlocked.
Renekton is Early to mid game champion, late game is his weakness, because he is just not powerful enought to keep up with other champions such as Tryndamere, Jax or Yasuo.
So what does that mean?
That means you have to do something in early game or mid game, for example helping other lanes push turrets or get kills, taking Drakes or Herald. When you don't know how exactly you can help your team or there is no Drake or Herald, you should be looking towards to split push. This allows you to get lead for yourself or get youself back in the game or get enemy turrets and make some impact on the map. When you split push you should be thinking about few things: If your team neefs your help – Then you can TP to nearby ward ; If there isnt any thread : What do i mean by that? I mean someone who you can't beat in 1v1 or push better than them.
