Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Renekton, Hitter or Tank? We have own different build for our own different champion. The only question is "Do you want to stay longer in battle and kill each of your enemy?". Check this build and use it in the real world of league of legend.
Armor Penetration, helps you to lower your opponents armor to increase your skill damage. Remember Renekton's 1st, 2nd and 3rd skill are all Physical Damage.
Health Regen, helps you to regenerate your health faster in early game. Also remember less pots less variant.
Cooldown Reduction, helps you to decrease your skill cooldown. Remember most of the time this Renekton doesn't use normal attack. This Renekton can kill only using it skill so be smart use this rune.
Armor Penetration, just like greater mark of desolation rune.
Every battle this build will act as a tank not a hitter so get 21 points in defensive mastery and 9 only in offensive. Remember TANK not a hitter.
As you can see in my items most of it are for tank items, You know why? Simply because it will help you to stay longer in battle. And the only thing I use to increase my damage is the Atma's Impaler. Imagine if Renekton's maximum health is 4000, 2% of it is 80 and that 80 will add to your attack damage. That's the Effect of Atma's Impaler, see it really helps.
This item helps you a lot in starting game. +100 health, +10 armor and +8 health regeneration per 5 seconds.
Mercury's Treads adds you +25 magic resistant to reduce the damage from magic skills and to reduce the duration from disabled skills.
You see that I only add my 2nd skill at level 13. 1st skill and specially 3rd skill helps you a LOT in creeping and jungling so you can buy your items in no time. 3rd skill also for escaping and entering the battle, be sure only that if you use dice you must also you dice to double the damage.
I use Exhaust and Heal. Exhaust for slow and to escape from one opponent. Heal is optional.
One thing is for sure, If you have brain "You Can KILL while You Tank".
