Okay I made this guide because I looked at some of the guides on here and didn't see my idea which I believe is original and great. The Zeke's Herald is one of the best items for Rengar. I mean when they changed starks fervor into this item I was wondering if it would even have any use but the cooldown reduction is so needed on him and takes care of his need for lifesteal for sustain and who doesn't love a little extra health and the attack speed bonus and team help is amazing. This guide is centered on the AD with it's great burst and a tanky survive-ability. This build is recommended if you have another teammate tanking.

The runes are pretty straight forward AD per level to add to the late game burst and some extra hp to make the ferocity W heal more and just that much more survive-ability.

The 21 in the offensive tree just for that burst and the 9 in defensive for that survive-ability to make sure you get that burst off preferably at least two full times in a team fight.

The trinity force is pretty straight forward it helps with the great burst and gives you about everything you need (with a little unnecessary mana). The bonetooth necklace is a must have on Rengar and berzerkers greaves help with his Q's attack speed bonus. The reasoning behind the Zeke's Herald is explained in the but it is the perfect item for him. A frozen mallet gives him the hp for sustain and combined with your E, ultimate, and ability to jump from bushes no one will be getting away from you. The black cleaver just makes it so that you can kill people that much faster but can be swapped out for a madreds bloodrazer if you need more armor or a maw of malmortius if you need more magic resist.

His Q is his main damage ability so I max it first followed by his W for the bonus armor, magic resist, and AoE damage leaving his E for last.
