Standard AD runes will work most of the time. CDR is not needed since you will reach 40% through the build path. Hybrid Penetration Runes are pretty nice on Rengar Tank since most of the time you will be using your W to trade.

Hey guys! My name is Spaghettis Mom, I go my Mook to most people that do not know me personally. I started to play LoL first in Season 3, but I did not really give the game a chance. Mid Season 4, around May, I decided to come back to the game and I fell in love. I got placed in Silver 5 in season 4 and stayed there.

In S5 I climbed to Platinum 2 playing mainly full damage Rengar top but I decided to take a break from the game in the summer and decayed to Platinum 5. My love for Rengar came from a streamer by the name if Avaail, who still streams to this day.

Season 6 was a hard time for me since Rengar was banned almost every game in the begging and then some nerfs to him made him a less favorable build. I then started to experiment around with different Rengar building that I had known about and decided that bruiser Rengar was the best way to currently play him.

Like I said before, Standard ad runes should work for this build. However I do recommed taking Hybrid Penetration marks as they will really help you with some extra damage.
