I originally posted this expecting critical advice. I know that my build is kind of underdeveloped but I really hit a rut making one for this guy. I hope to update it based on the public opinion but I'm not getting much for comments, feel free to speak your mind!

@ Shin Usually ap does make your abilities hit harder. However, Ren and Pantheon are unique in that they are physical casters. This means thier abilities scale off their auto-attack damage instead of their ability power. The only benefit AP gives to Ren is on his ult- there is some magic damage associated. The rest of his damage is physical and scales with AD.

such a ripoff lol

Why does he not need ap? i thought adding ap would make ability attacks more powerful?

Awesome build. I used this for a few games, my records were like this: 12/2/15, 20/0/9, 6/3/10. I agree with it completely, I'm glad I found it since I was having trouble making one myself.
