How was your day? - League of Legends edition

So apparently, my friend recommended me to try out Renekton. He's sort of okay but I'm kind of confused on how he works.
If I understand it right, his fury part activates when he attacks a minion/champion, right?

Any Renekton pro out there who would like to share their tips and tricks?

First off, play this song:

Okay, here we go. Renekton is mainly a lane bully early on. You will pomegranate on most people, it's an eventuality.
He gains Fury when he autoattacks (also applies from non-fury enhanced W, but fury-enhanced W will not get you more fury), from targets hit by his Q, and periodically when his ultimate is active. Combined with his passive, this means that he doesn't really have to focus on autoattacking when he has his ult up because he's going to be getting a lot of fury. To make it so that you can comfortably sit at <50% HP in a teamfight, you want to stack health. Sunfire and Warmog's are both naturally good pickups for Wizard Lizard because of this, and even more so since health is so strong right now. You use your fury to enhance your Q W and E. There isn't a set fury-enhanced ability that you want to prioritize, each ability is good in different situations. When you have more than 50 Fury, the next basic ability you use is enhanced and consumes 50 fury.
One of the annoying things about him is that his W basically stuns him as long as he stuns his target which is bad in a teamfight. Fortunately, the Crescent active from Ravenous Hydra or Tiamat actually completely cancels the animation of W. Abuse this. Black Cleaver is a good item for him as well. You'll probably want to rush sunfire and either tabi or mercs after sunfire (you can get tier one boots before sunfire but meh) then Cleaver if you want to focus on damage and Warmog's if you want to focus on never dying. Hydra should come around this point now. Throw in a Frozen Mallet somewhere if you like sticking to people or just get whichever one of Cleaver or Warmog's you didn't get, whatever. Maw/Hexdrinker is situational but can be very good given its synergy with his tendency to stack health and stay at low health. If you want to focus less on damage but still need MR, hit up that Spirit Visage.
He's extremely good at using Slice/Dice to get to the back line and maneuver in a teamfight and can effectively shred tons of armor with the Fury empowered Slice/Dice (even more so with Cleaver). But his main strength is definitely in how he can bully people in lane by abusing his E W (Q) E combo fairly early on and just get kills. Keep in mind thought that without kills or a significant advantage going into midgame, he's not that good.
