Here is a build that works really well for me. If you dont think its any good oh well. This build is awesome I dominate with this. Everything goes really smooth together as in the reason i got some thing is because it balances out what i already have. So its a pretty balanced build.

The runes help you a lot at the start. The marks boost your magic penetration which helps push enemies at the start. The seals give you a killer defence letting you lane a lot longer and to push and tank a turret. The glyphs do the same as seals just against magic. The quintessence just boost everything even further.

This mastery is great it give a ton of defence so its easy to just attack a enemy with running away. You can just sit there and take all the damage from you enemies while you attack and your allies can easily defeat them thats if you dont kill them first.

The item build is really good at the end of a game you'll dominate and you dont really need to rush to get it, it takes a little time because as i mentioned the runes and mastery helps a lot in the start.

This is just the best way i see to lvl you abilities cause you wont need brutal strike til closer to the end.

Ghost is for if your are heavily damaged you can get away easily and the Exhaust is for when your enemy tries to escape when they are low on life really helpful.

Well you can try this build its really fun and can be a very affective build.
