Rengar is a melee assassin champion, who is an extremely well jungler, but can also lane as well. He fights using high damage abilities to take his enemies down quickly. In this guide, I will explain his item build, masteries, runes and tricks he can use.

this is one of my first build's i'm not pro guider.

Pros

very good assassin
Amazing early game
Good farming capabilities
skill that collaborate well
good at escaping


Cons

squishy early game
not very good without farm
CC=Worst enemy
weak against tanky Champions.

I take 21/9/0 in masteries taking damage and armor penetration, as well as some extra damage to minions and monsters for jungling and farming. In the defense tree, i take the magic resist/armor and health masteries, for extra durability.

In runes i take pure damage marks, health seals, attack speed glyphs, and movement quintessences. This helps with his abilities at the beginning of the game. The marks and quintessences help with more damage en follow speed that can get kills in the beginning. The glyphs and seals give extra attack speed en health for quicker damage and a strong health in in early game so you can take more damage.

So what i suggest is taking Ignite and Flash. Ok so personally i prefer flash over ghost but if you want to take Ghost in place of flash as a replacement if you like that more. And if you want to get rid of ignite because you just don't like i guess i would suggest replacing it with Exhaust or Heal for the sake that they are the only possibly good summoner spells i have used on Rengar or at least found useful.

I start at the wraith's Camp, followed by the wolf camp. Next I move to the Lizard Buff, followed by the Golem camp. Lastly is the Ancient Golem buff. The entire time look for ganks. At level 11, Rengar can kill the dragon if used correctly.
