Max your W, then Q, then E since Q's flat damage is enough and E isn't worth maxing first. W will leave your opponents crying. Your items start by giving you a damage edge and then aim for you to become more tanky whilst maintaining damage and CDR. Aim to E through minions for ganks to get a quick slip in. And a big tip, While you are using W, use Tiamat and Challenging Smite for extra free damage they can't do anything about. Guaranteed to pop a flash or get a kill if the laner is aware.

In short; No. Renekton Jungle is not troll.

Renekton is a powerful, resourceless jungler who excels at bursting down the enemy when he catches them. The most important skill to Renekton Jungle is his W, Ruthless Predator. It is an auto attack resetting skill that triggers 2 auto attacks (3 if empowered) and stuns the opponent for 0.75 seconds (1.75 when empowered). When ganking lanes he can dash through minions with his E Slice and Dice to close the gap between his enemy and himself. When counterganked, Renekton is even more dangerous since he has to use Dominus which makes him a nightmare to deal with.

Early game is where he struggles the most, finding it difficult to gank if the opponent is not in the middle or pushed up in their lane. If he has red, this is a tad easier to achieve but otherwise he needs level 3 and a slight advantage. While he deals a lot of damage, he does usually require the allied laner's help to take someone down from full HP if Flash isn't popped.

Middle game is where Renekton shines. Usually you have Skirmisher's Sabre and Tiamat at this point (if not better) with Boots aiding your ganking. Technically this is where, through-out the game, Renekton finds his biggest powerspike. All the actives provided make him a threat to watch out for. And if he encounters a ward he has the greatest of ease killing it.

Lategame, no matter how squishy he's built, Renekton finds a way to be tanky with Dominus. He gains a substantial amount of HP while this is active and an empowered Cull the Meek can sustain him really well. He is also somewhat slippery as he can go through a small number of walls with Slice and Dice allowing him to surprise opponents with ambushes and killing them alone. After getting Titanic Hydra, every hit from Ruthless Predator whether empowered or not will proc it increasing your damage substantially.

Precision - 9% ATTACK SPEED BOIIS THE GOD (it's alright, tbh.)

Press the Attack - Ruthless Predator is procced almost instantly upon using this, increasing damage your first hit by a lot and after it by quite a lot as well. Conqueror would be close, but with how "free" Ruthless Predator activates Press The Attack, it's too good not to go this route.

Triumph - Overhealing and Pressence of Mind don't benefit us much. In the middle of teamfights, 12% of your HP is quite a lot especially when you're using your ultimate. The gold's just a good bonus in my eyes.

Legend: Alacrity - While Tenacity is an extremely good alternative I find Alacrity to be more useful for the clearing and fighting later on. Generally if someone tries to CC us and get close, it ends with them getting hurt a lot more than us.

Coup de Grace - Our HP's level goes from up to down a lot so Last Stand becomes unreliable. You'll be hard-pressed to find something you -have- to kill with more HP than you so bye Cut Down. Leaving Coup de Grace to give us execute bonus + AD on kill to keep the fight in our favor. Nice!

Domination - Yay, 6 AD. Nice little bonus.

Ultimate Hunter - You'll be focusing on ganking, and different lanes, so inevitably this will become very useful as you're most powerful when you're in Dominus.

Cheap Shot / Sudden Impact - It's honestly a toss-up with this. 8-40 True damage after CC with Cheap Shot which we get for free, 7 Lethality because we used Slice and Dice? I go with Lethality personally but Cheap Shot is just as strong of a choice.

Skirmisher's Sabre - Have I mentioned that Ruthless Predator is incredibly strong with this? No? Or that it also procs Press the Attack? Yeah, just get this one for the damage. Even with Stalker's Blade if the lane isn't in the middle or pushed you won't be doing a lot of useful stuff with it. Only get Stalkers if you have a REALLY slippery enemy team and you see no other option of catching up.

Enchantment: Warrior - Looking at all the benefits that Enchantment: Cinderhulk gives versus the early benefits of Warrior, I choose to give Warrior the edge over the reason that it helps your early game too much to pass up. Since Renekton's resourceless his biggest hindrance is Cooldowns. So bring those down, right? Early damage benefits Renekton.

Tiamat / Titanic Hydra - Tiamat can be activated while using Ruthless Predator meaning the damage increases entirely for free. The HP gains from Titanic Hydra are too good to pass up along with the damage. It also means we die less quickly in fights. Plus, this active also benefits us greatly.

Black Cleaver - Breaking someone's armor is incredibly easy for Renekton. Along with this, we move faster if we hit the enemy, provides us with HP and Damage, and dear god yes CDR. Too good to pass up.

---

Sterak's Gage - This is generally also considered a main item. In fights, we gain more damage while also getting our HP to go up tremendously after it activates. But if need be I don't mind substituting it out for the next item on this list;

Frozen Mallet - Kind of an odd choice. The reason I run this is 700 HP along with the passive. It allows people to catch up as it slows the enemy, whilst making you stick like none before with Black Cleaver's Phage passive carries us forward. This one provides more utility, basically.

Maw of Malmortius - Defensives, CD, bit of Damage. Nothing else to say. Useful but not priority.

Stormrazor - The oddest choice on my list in terms of all items. The reason I choose it is because it makes you more of a threat when you catch someone, lets you build more fury and do more damage as a result of attack speed, and the movement speed passive along with Black Cleaver's makes you speed gonzales for a moment.

Sunfire Aegis / Gargoyle Stoneplate / Adaptive Helm - These are generally items you should build if you find yourself in the center of a teamfight. One provides defensives, one deals damage that synergizes well with your ultimate's damage. Helm actually gives you some CDR as well and is more magic damage oriented.

Dead Man's Plate - My personal choice. The defensive additions are good, but the movement speed passive makes you a shark in the water. Slight slow when you proc the stacks, more damage, and catch capability. Not bad, not bad at all.

Zeke's Convergence - Huh? A support item? Well the defensives are good and who doesn't like a bit of CDR. But the main reason you'd build this is to help your team and your ADC. Since you'll be using your ult every teamfight, this gives your team the opportunity to catch up when they're slowed. Plus, all slowed enemies receive more dmaage from the ADC's auto attacks. It's pretty useful and really damn underrated in my eyes.

Renekton is not typically seen as a jungler, but actually packs quite the threat with his Ruthless Predator (W) skill. An empowered Ruthless Predator will instantly trigger Press the Attack, leaving Slice and Dice along with Cull the Meek to finish the job.

Renekton is extremely strong in 1 versus 1 situations when he has 50+ fury which is quite easy to build up. People looking to engage when he is level 6 and you're on even playing ground will find them quickly decimated. His Ruthless Predator with stun and proc Press the Attack while the empowered Cull the Meek will deal insane flat damage, heal and leave you begging for mercy.

Early on his items aren't super required, but once he gets going he's hard if not almost impossible to stop on your own, unless you can kite him.
