JUST WANNA SAY SOMETHING FIRST.DON'T SAY THAT THE STATS ON LVL 18 SUCK CUZ WHEN YOU GIVE MORE THAN 6 ITEMS HERE IT DOESEN'T COUNT ALL OF THEM SO YOU WILL HAVE WAY BETTER STATS THEN THE ONES DISPLAYED HERE.I just wanted to give the full order and then i saw the stats.


Ok hi ppl that is the first build I post here so maybe it will suck a little.The reason i post it cuz i see many renekton builds here but i don't think that they are good enough and i see ppl suck with that champion every day :X and i don't mind but they are giving me a bad name cuz when i enter a game whit renekton and ppl say omg another one that will suck screw us.So maybe you won't like a lot of things in the build like for example the runebuild cuz everybody are like oh yea i must have max dps runebuild for my champ i have to be a care and so on.Just leave me feedback whit your opinion and i'll fix something if i am wrong.

PROS:
-good farmer
-pusher
-high mobility
-off-main tank when needed
-easy multikills in teamfights or alone cuz of his 3 AoE abilities
-great healing ability whit cull the meek

CONS:
-Squishy early game
-silece ***** him up if chain silence
-can't think of anything else

Ok many of you will say that the champion is squishy and need to be played whit tank masteries but for me the point of that champion is not to be a tank,he is just made to be a tanky dps.So i think the masteries in offense are clear.So for the other 9 extra point you have.Why do i have the points in extra armor and magic resistance because you are squishy before you get you warmog and some extra def against dmg is aways a good idea in early game.The other thing i think ppl will have problem whit is why are the other 3 points in utility on perseverance and why didn't i put them on dodge for example or improved ghost.The thing is i will get 2% dodge ppl wake up 2% dodge procs on every 50hit so i won't count on it.Why not improved ghost thats a good question if you want it is a great idea but for me the hpregen is better.

Why do you go for cull the meek first?
It is a very underrated ability the healing is great and the AoE dmg is not bad its good to max it first cuz you have better chances of living from harass or ganks better used in the midle of as much possible creeps for max heal
high dps ability best use when you have rage 250% physical dmg +1,5 sec stun
best harass ability ever.just use it like on the champion spotlight.You can use it to escape ganks or to chase someone down too.

Ok the runebuild will be the thing that will make most of the dislikes.Many ppl don't like the runes but in a combination with the masteries and items you will be good from lvl one.
Ok first of all why armor penetration mark why not flat AD or pet lvl AD.Ok the answer is simple cuz in mid-late game you get more bonus dmg from them.(they buff the abilities that do physical dmg too).
Now that will be the most hated part of all the seals.Why the hell HP/per lvl man you suck.Ok again its pretty simple you can die easy and the other primary runes are not soo god on my opinion.
-The 0,75% dodge one hmmm don't know not a big fan of the by chance things i don't want to nerd rage because it didn't proc.
-The armor ones don't know think will be better to have defense against both physical and magic dmg and what is better than more hp ofc ;P
-Why per lvl ones and not flat.Cuz the per lvl ones will give you more hp on lvl 5-6 than the flat ones(flat runes bonus hp:50hp ; per lvl runes:180hp on lvl 18).
Ability cd reduce is one of the best thing for renekton cuz he is dealing most of his dmg with abilities not with normal attacks.
I think that hp quints are the best ones and since renekton is squishy and need some extra hp they are the best choice for him.

andwhy did i pick ghost yes you are a high mobility champion but from time to time you need a little boos to catch someone or to run away.As for the exhaust spell it is away good to have a slow or debuff for less dmg (pls don't forget that from last patch riot changed the spell so now it reduces ability dmg too so if you see a caster that is about to burst you maybe its not a bad idea to exhaust him).
Ok some other good choices are:
It is away good to have extra dmg for someone who is trying to get away and the healing reduce from the spell is very underrated it is so awesome against champions like mundo,vlad and so on all the champions whit heal effects you get the point.
is very good too cuz a big part of the time the enemy team will focus you because you will repeatably stun them whit the cd reduce and deal good AoE(area of effect)dmg whit all of your other abilities.
what can i say one of the most imba summoner spells in the game you can chase with it,towerdive with it teleport over walls for chase,ambush,run etc. so ye mostly its good for every champion to have.

Ok its a bit late now and i don't want to explain why all the others suck but if someone in the comments ask for a spell i will post it.

Why the hell do you start with pendant cuz its a good idea to rush warmog's armor.

BASICALLY THESE ARE THE 3 COREITEMS OF THE BUILD:

(warmog's armor)-the reason this item is the first you get is that you are a mele champion whit a squshy hp(when you don't have ult) it just gives you the hp kick you need till the end of the game.
(Atma's impaler)-is a great item for you cuz now you are a tanky dps so the extra dmg from hp is great (don't forget that you get extra AD when you use ult because of the extra hp it gives you) and you get some more armor and crit chance which is basically the greatest thing ever.
(Youmuu's ghostblade)-the item is from the recommended ites and its rly great some extra armor penetration,more crit and extra movement and attackspeed on use just don't forget to use it the item is rly imba.

OK NOW FOR THE OTHER ITEMS:
Ok now for boots you can get whatever you want depending on the enemy team but for me the cd reduce ones are the best.

Items for the last 2 spots:
I go for a crit build but you can go for more armor penetration or lifsteal they are all good you can even make one more def item and it will be good so its your choice but i highly recommend the crit build
(Phantom dancer)-is one of the best items for the crit build it gives you more ms(movement speed) it gives you crit and attack speed what else do you need to be a insane good mele.
(Infinity Edge)-is there a crit build whitout it? the item speaks for itself.

Other good items you can use:

FOR OFFENSE:

1.If you wanna make a lifesteal build:

2.If you wanna make an armor penetration build:

3.You just have a high hp team against you:

FOR DEFENCE:

1.A little more hp and slow:

2.Against a high physical team:

3.Against a high magic dealer team:
4.If you just die too much:


Didn't explain a lot of the posible last 2 items,i just think they speak for themselves.
Will update with new info if you give me interesting ideas in the comments thx for wasting your time reading my guide ^^ .
