I love Shaco pretty much. But I hate it, that he can be countered pretty easy especially in the lategame. It's easy to get so fed, that you carry a game alone, but this will only happen at low elo and normal games. I tried to work out a build that makes him also pretty awesome in the lategame. Even if countered with , or alot of burst. So I build a tanky version of Shaco, who has also some utility and still the ability to pick off the enemies ad carry quickly.

Since Mobafire wont show the real stats I will sum them up.

Shaco has 114.7 basic AD at lvl 18. Your masteries will give you additional 12 AD at lvl 18.

He will get 30 AD from and 150% of your basic AD from the proc.
So it deals 1.5 x 114.7, what is 172 damage.

will empower your damage to a new level. 80 AD and 0.5 to your critmultiplier.

increase your damage by 2% of your total health:
1953 (basic) + 250 ( + 330 ( ) + 138 (Masteries) = 2671 health!
2671 x 0.02 = 53.42 AD, since you have 114.7 basic Atma's will give you 54 AD.
With you would also hit 2906 hit points and so on 58 AD from .

Finally a will buff your AD by 100!

And now... let's sum it up :D

114 + 12 + 30 + 172 + 80 + 54 + 100 = 390 + 172

Since the proc wont scale with your critmultiplier I wont count for further math.

Your basic critmultiplier is 2.0.
Masteries give you 0.1.
give you 0.5.
So your critical basic attacks will deal 2.6 x 390 = 1014 + 172 = 1186 damage. If you combine your basic attack with you will also deal 1216.8 + 206.4 = 1423 damage.

will deal a lil bit more on it max rank.
Your critmultiplier will be at 2.8 with on rank 5.
Since has a 100% critchance it will deal 1092 / 1264 damage and 1310.4 / 1517 together with .

Think about that damage! - And don't forget , it deals 75% of your basic attack damage!

Shaco is an kickass assassine, who is strong on every map. His physical burst is incredible and it's always fun to play him. To be an assassine there is only 1 thing to do:
Avoid wards and from a hidden location...

It's pretty easy to hit an enemy carry from behind with ,
then with another autoattack, which has a 58% to be critical and then a , which will make escaping impossible and deal 395 magic damage. In the most cases your target will be down after Q + critical autohit from behind. Enemies start stacking armor? Who cares you can also rip non tanks apart if they have 150 armor. If you get focused in teamfights, you will still have your CC with ,your ultimate, your tankiness and a combination of and . Aslong your enemies dont have tons of cc and oracles they wont be able to kill you, especially if you kill their carrys with two hits.
