Hello everyone and welcome to my Rengar Guide.

On every wall of his den, the trophy hunter Rengar mounts the heads, horns, claws, and fangs of the most lethal creatures in Valoran. Though his collection is extensive, he remains unsatisfied, tirelessly seeking greater game. He takes time with every kill, studying his prey, learning, and preparing himself for the next encounter with the one monster he never managed to defeat.

Rengar never knew his real parents, but was raised by a human who was revered as a legendary hunter. He was an ideal pupil, intently absorbing the lessons of his father, and improving them with his uncanny feral instincts. Before his mane had fully grown, Rengar set off on his own and claimed a wide territory for himself. Along its perimeter, he mounted the skulls of his slain prey - a warning to would-be aggressors. He thought undisputed reign of a region would fulfill him, but instead, he grew restless. No beasts in his domain proved challenging prey, and without formidable adversaries to push his limits, Rengar's spirit waned. He feared that no worthwhile game remained, that he would never again feel the thrill of the hunt. Just when things seemed their bleakest, he encountered the monster. It was a disturbing, alien thing, distinctly out of place in his world. It bore huge scything claws and devoured any animal that strayed across its path. Overzealous at the prospect of a challenge, Rengar ambushed the monster in haste. It far outclassed anything he'd hunted before. Their fight was savage, and each suffered crippling wounds. Rengar lost an eye, but the most grievous blow was to his pride. He had never before failed to make the kill. Worse yet, the severity of his injuries forced him to retreat. Over the following days, he hovered on the threshold between life and death. He was wracked with pain, but beneath it, he felt a glimmer of joy. The hunt was on. If such powerful beings existed in the world, he would find them, and stack their heads high. The monster, however, was a kill he wanted to savor. On his den's largest wall, he reserves a space for the beast's head, a trophy he swears will one day be the centerpiece of his collection.

''Prey on the weak and you will survive, prey on the strong and you will live.''

Greater Quintessence of Attack Speed If you combine the Attack Speed of the runes with you Savagery, you will get quickly attacks.

Offense Tree:
I put one point for the Exhaust, so i can reduce the armor and magic resist by 10.
A little bit of strenght.
More quick the attacks.
More armor penetration for the armor.
More Damage.
When you get you Zeal or Trinity Force it will works very good.
Just in case that the enemy have extra armor.
If you combine the 6% with the Havoc you will have 7.5% of damage dealt.

Defensive Tree:

Mag.resistance for the AP jungler
You will need it cause at early game your armor is very weak.
Maybe the same case with Hardiness if you want to stay more time in fights.
Veteran's Scar A good amount of life

Wriggle's Lantern
I like to take this item cause it will give you armor,attack damage and a decent percent of life steal also that his passive is useful in the jungle with the monster and the active also.

Boots of Mobility
There are sometimes that you will need more speed, that is why i choose these boots, to travel in the jungle more faster and to catch the enemies more easy.

Bonetooth NecklaceBonetooth Necklace
An item that will give you differents bonus effects based on the number of trophies he has.

Trinity Force
I like to start building Phage, so i can slow the enemy and kill them if they try to runaway.

Maw of Malmortius
I start with the Hexdrinker if i have problems with the AP carry at early game, because the shield that have it can save you the life several times, then i can build it more later in the Maw of Malmortius.

Guardian Angel
I love this item on Rengar cause if you are in a team battle and you did good like killing 2 champions, but the other champions with the low health killed you, you have a second chance to finish them.

The Bloodthirster
I placed a seventh item because you are going to change your Wriggle's Lantern for this item in late game because it have more life steal and more damage which offset the lost
