I would like to give this builds credit to WTBpwnage because all I did was tweak his.
For a description of how to play, read his.
This is just showing a few variations that will improve his build.
I changed up the runes to fit my play style, this change is very minor and lacks importance, but I threw it in.
As you can see, I took out his third sunfire and added zhonya's to the end, this helps a lot and makes for some serious damage when combined with your majai and Lich bane.
3. Summoner Spells/Masteries
I replaced the heal in his build with ignite and changed the masteries to support the new change. This new change makes for added damage when you just need that little bit more "pew pew for you laser" in the early and sometimes later game.
Thanks WTBpwnage, Hope people like this.
If you like this build please give WTBpwnage's build a +1 also.
