this is my firtst build. before you rate pls comment.
With this build nothing will stop you in the endgame. in early and mid game you can get aggressiv ,but only with the right partner!! one rule: everybody with stun/snare etc. is a good partner for you.

skills:

Reckoning: this is a very stron ability and great to harris. try to use it everytime it'a possible
Divine blessing: with this you can heal your self instead of going to base and the speed boost allows you to get the enenemy.
Rightous fury: this ability kicks *** man!

Early/mid game: With the right partner you can start kill the oppenent ,but even if you play devens you can harris with reckoning or righteous fury.

Late game: right now nothing can kill you. even if you get ambushed you can try to kill one of them and then get away with blessing and your ulti. with all the ap you have your dmg shout be awesome!!

Items;

i like starting with an dorans ring, becasue it gives you healt,ap and mana reg and this is brilliantly fot u. after that i try as long as possible on my lane and get as much gold as i can so that i can buy at the first time back in my base boots of speed and the hole ragebalde,
if you are able to get the rageblad very early its gonna be very funny. it will be like this:
you walk back to your lane, see an anemie , say somthing cool liek "lets rock" and just facstomp him befor he can realize what happened. th next itme i get is the hextech gunblade, because if you have rage+gunblade and activat you range attacks you will do hellarious dmg and heal yourself incredible strong. actually the game should be over at this point, but if not i really like to buy a nashhors tooth ,because kyle is abit slow with her attacks. wehne the game isnt over after that there are two things to do: 1. flame your team ,because you do all the dmg 2. get a starks fever. with the complet build you heal yourself with each striks for somthing about 40 i think (without fury!)

i must say at this point that i never got farer then to nashor,but this match took sth about 1h.

One kast tipp: kyle is very dependend to items so dont be to aggresiv at the begining (exept for the fact that you have full ap glphyss and seals and marks and quintesences)

have fun with this build and let them know what Kyle can do!! pleas comment your rating ;)
