Hi fellow Summoners. Just a few words with You and I won't waste your time anymore.
1) I won't bother me or you to write 10 paged guide. I'll make it as short as possible, I'll give what you need (build) and just a few words on it + some advices and OFC Farm-Timer.
2) You do not have to follow item purchase order i gave to you (Choose your own path), but i higly recommend it.
2a) Don't forget to use active part of Yuomuu's Ghostblade. If you do forget to use it it's worthless item then....
3) Just a small advice: DO NOT ****EN USE E TO CLEAR MINION WAVE. You will loose your Q stacks, and that ain't good.
4) Don't like my masteries, don't use 'em.
5) Don't like my runes, don't use 'em.
6) The reason that i don't have VS. Champions section is because it is not champion that counters you. It is the other player, and other player ONLY that can counter you. Not some "over powered" champion; that is just a bad excuse.

Farm tips:
1) Always Q Siege minion, and as much other minions you can.
2) Once again, don't use your E spell for wave clear, it will **** up your farming on Q.
3) Don't buy AOE items that can mess with your farm on Q (Sunfirecape & Ravenous Hydra; Iceborn Gauntlet is dependeble item....)

Farm-Timer: Something i tried to make, but can't call it accurate. It will show you how much farm on your Q you should have at some game stages:
12:00 minutes: from 80 to 100 Q stacks
20:00 minutes: from 300 to 400 Q stacks
30:00 minutes: from 450 to 700 Q stacks
Later on: Whell if you manage to hit 700 stacks on Q it should be GG for your team.

That should be it. If you do not like my guide, don't bother to leave negative comments, just derate it, or if you like it just rate it up.

Farewell my fellow Summoners, see you on Fields of Justice.
