Rune Build:
Crit chance FOR THE F'ING WIN!
Quintessence: See the late game tip.

TALENT TREE:
Depends on your two secondary SKILLS.

SKILLS:
Flash/Exhaust/Ignite/Sprint
Depends on what you want to do.
Me my self use Flash and Ignite.

I use ignite for last hit K.O dmg when in need of money.
Or to harass so one have to recall so he loses EXP. 1 or 2 lvls ahead of an opponent
makes it easier for you to chase him away from minion EXP range.
Flash for Tower escaping or escaping opponents.

Sprint:
Better for moving to a location to help a team mate with gank or survival.

Exhaust:
Waste in my eyes but good for keeping your range. Run shoot, Run shoot. Or exhaust and let a team mate with more health do the base dmg where you stand in the background firing and TUBMLING back to not get in danger.

Start off with dagger and spec your "CONDEMN" abillity first for knockback into the wall so the opponent gets stunned, BUT! dont be too greedy with a kill. And ofc go lane with someone
so you can get an early kill/assist!
After a kill or assist and some minion kills. You have Berserker Greaves early
game, which is good!
This is the point where you choose to spec the "SILVER BOLTS" for more minion kils.
Two shot then move all the time and take the last hit for easy gold.

OR you can spec "TUMBLE" for easy dodging or harassing the opponent which is good early game, because you might meet some players with high damage early game. Like Trynda + Crit rune build and so on.

Choose your abillitys carefully!
Are you going for early game assist Vayne (recommended): THE CONDEMN - TUMBLE all the way till level 6 were you spec your ulti mate FINAL HOUR ofcourse.
Early game gold farmer: SILVER BOLTS - TUMBLE
or are you going for early game harass ganker: TUMBLE - THE CONDEMN - TUMBLE
or hybrid action: SILVER BOLTS - THE CONDEMN - TUMBLE. (for gold farming and assist/kill)

MID GAME TIME!

okey, so.

You're about level 6.
You finally got your Ultimate. You have like boots, almost phantom dancer if
you went hybrid action: SILVER BOLTS - THE CONDEMN - TUMBLE.
You have full crit runebuild:
CRIT CHANCE
QUINTESSENCE: CRIT DAMAGE.

YES MY FRIEND! Crit damage! Because of your SILVER BOLTS, TUMBLE AND FINAL HOUR.
The Quintessence runes are so damn nice late game too! which im coming back to later
in the "Late Game Tip" Guide..

REMEMBER! Do NOT get too greedy with the ganking. You might fail and the small ammount of 300 gold might be enough to make you a kitten in a cage with a gang of animal loving rapist.

Because of your "THE CONDEMN" you can make your lane mate gank mid or bot/top.
Just tower hug. In the end one smart *** will tower dive. So make sure you stand between the tower and the wall. Thats when you ran back towards your base, TUMBLE towards mide THE CONDEMN the opponent in to the wall(make sure he hits you once so he gets TOWER AGGRO)
POP FINAL HOUR fire, tumble, fire, fire and he should be dead by now.

Tell your lane mate to SS back wile you tumble back towards your next tower if you can still see the other opponent next to the tower furthest away from your base.

After having your sexy boots, *****luving phantom dancer.. You take a FAPPPP and start going for INFINITY EDGE - go for B.F sword first because of the dmg. You have the CRIT RUNES for CHANCE and DAMAGE. So B.F sword will help your ultimate FINAL HOUR to deal more damage.

Go mid lane and gank there for a mice and luvely assist or kill. Then pick up your mid lane team mate and charge for bot gank/harrass so bot lane can bring down a tower.
If you're in trouble you have THE CONDEMN and TUMBLE.

REMEMBER! Jungling wile towers are safe = BEST YOU CAN DO!
Money = most important so you can build up your item build.

You should now have smuud luving BOOTS, ***rippin PHANTOM DANCER and the hardcore rape machine INFINITY EDGE!

Start building up for THE BLOODTHIRSTER

Final stage of the guide. I will post more later on ofcourse!
Just throwing in my game style for now.

You should have BOOTS, PHANTOM DANCER, INFINITY EDGE and BLOODTHIRSTER(Good for jungle minions to get up your stacks and buffs)

this is where your QUINTESSENCE runes CRIT DAMAGE will be awesome!
You now have INFINITY EDGE and PHANTOM DANCER which gives CRIT CHANCE
but still! NOT ENOUGH! your goal is to get 100% CRIT CHANCE.
So get ready to go for two more PHANTOM DANCERS.

ATTACK SPEED, LIFE STEAL, CRIT CHANCE 100% and CRIT DAMAGE 14% ++

Remember in huge group fights. You should be the one last charging in for your own safety.
Make sure one of you mark one opponent to focus. If you're the first in or second one in. The other team will focus you because they KNOW you're dangerous now and you need to be brought down!

DO NOT pop FINAL HOUR at start. Kill the first one. THE CONDEMN one oppononet which is after you, TUMBLE away him but towards your next target. Pop FINAL HOUR kill! now run towards your next opponent flash behind him, TUMBLE towards your base if needed or closer to an team mate. Keep moving till your THE CONDEMN are ready. Bait one of the away from the group fight to split the other team up THE CONDEMN on the opponent into a wall so his stunned. IGNITE, fire, TUMBLE and run.

YOU are the key player to kill opponents or assist your team mates to kill one wile he tanks the damage or to save your team mate in danger.

IF you want to be able to solo BARON. Go for 3 PHANTOM DANCERS, 2 BLOODTHIRSTERS and INFINITY EDGE.

You gain movement speed from the PHANTOM DANCERS so 3xPHANTOM'S will be as good enough as boots and some more speed. Make sure to stack up your two BLOODTHIRSTERS before going for BARON. This is also good. Your team mates can keep the opponents bussy wile you kick BARON'S ***. Still make sure your team mates DO NOT DIE! Tell them to harrass, keep moving and dont let them come to BARON. In that case.. YOU'RE RAPED and the other team gets BARON. THE END...

I will update the guide later.
Please feel free to comment. Negative comments GTFO.
I would rather prefer tips from others that are helpfull or what you think about the guide
and if it worked well for you.

HAVE FUN! GOOD LUCK! AND KILL SOME WIMPS OUT THERE!
