Yes,I do have a clue of my runes.

You dont have a clue about your runes do you.

I would like to tell you aquaboi,thanks for the guide! It will really imrpove me and help me play Xerath,because i'm a total noob with him. Thanks!

For xerath's combo, I'd suggest w q e r r q r. Keep in mind your cool downs can assure you more damage output.you should also add that if you try to land an e and q combo too quickly while using w, you can miss your stun because your q can hit your target before your e does even if you use e first.

Xerath benefits from AP to power up his passive. The more AP he has,the more bonus armor he'll get.

I got three things to say to you
1.Wall of text
2.No Bcoding
3. Why do you seperate runes into bunch of stats? Would Xerath benefit more Mp?
