con's
there isn't really any con's he has

The reason i got the runes is because Renekton uses Cool Down reduction for his moves. He also needs health to help him stay in the lane longer or turret dive with out any worry. He also needs the extra attack speed early for his passive. if you want even more attack speed to support your passive get more runes that have the name alacrity in it if you want more attack damage get attack damage glyphs or seals such as greater glyph of strength and greater seal of might.

Well the masteries are pretty straight forward. exhaust to help slow them even more or help you early game, deadliness for the critical chance early game which might help you, alacrity for the attack speed to support your passive, sunder for the armor pen, offensive mastery to help you farm more minions, brute force for the attack damage, lethialty for the critical damage for late game when u start to crit, havoc for the bonus 5% attack damage.

I got the dagger first for your passive to get furry quicker. get boots of lucidity for the cool down reduction to help you use moves quicker. i picked sheen to help support your Ruthless Predator move so you will deal even more damage. frozen mallet is helpful when they are faster than you and your exhaust is down plus the bonus health. zeal is for you attack speed and crit. Brutilizer is for you attack damage and cool down reduction. Trinity force is helpful with your attack speed and critical chance plus your movement speed. The BLACK CLEVER is one of the most important items it gives you attack speed and attack damage, even better it gives you even more armor pen. the ghost blade is to support your cool down reduction and gives you attack damage. if your going up against good carry's and your team feeds then get another phantom dancer if your just completely owning them then get a inf edge or a sun fire cape since it will stack with you ultimate. if your a noob and just dies a lot then i would recommend getting a guardian angel that way you won't die as much its pretty straight forward. if your going up against a lot of casters and cant stay alive then get some magic resistant and get the wit's end

max out cull of the meek as soon as you can except when you can level up your ultimate. get ruthless predator to help your sheen get stronger. slice and dice to run away or to harras the enemies. your ultimate of course to get you a lot of kills although i doubt you'll need it.

i picked ghost to help you to either run away or chase them. exhaust to help you kill them, save your partner, or run away.

the summary is that he's pretty easy to use and he get's a lot of kills and carry's most teams and isn't that easy to kill with this build i don't know about other builds, but yeah what ever. please comment and rate also i will take criticism or other wise i wouldn't have of made this awesome build that owns
