Hello fellow League summoners.
This is my first guide and I am really excited, how it will look like at the end:D!
If you have any Questions or criticism, PLEASE write them in the comments & help me improve!
First of all I want to tell you who I am. My name is "SneakyTwitch" an I am a new Shaco main. Last season I started to play League of Legends and ended the season as Silver V player.

I know, I still have to learn a lot about Shaco, but I really want to share my knowledge I have collected about him with you.
After my Promotion matches in Season 6 (I won 5, lost 5) I was placed Bronze IV.
I used to play some normals for a while and discovered Shaco. In Season 5 I always lost when I had a Shaco in my team and i began to hate this champion. (Like for real. I quitted the champion select, if some one locked in with him.)

Now everything looks different. I wanted to give him a chance in the new season and gave him a try. When I played Shaco for the first time I was really bad.
I could not invade, executed in the Jungle and was totally useless in the Teamfights. Anyways, it was a very funny champ & I decided to learn more about him. From now on I started to main him.
Its true that he is a very high skilled champion if you want to play him good.
The hard thing about Shaco is: estimate the situation & act right and carefully. He is a high burst, split pushing assassin.

To the proper thing I wanted to tell you. I am not Bronze IV anymore, I`m Silver IV. Do you know how I did this? Shaco.
You can not pick him in every situation. You need to look what champions your team wants to play & think about how your Teamfight will look like. If you have no tanky Champions its game loosing to pick a Shaco in the team. ( I will explane later)
You have to look that you team has at least 1 Tank, 1 Off tank and 1 Ap-Carry.

I played Shaco in every role, Top, Mid, Supp, Adc and Jungle. Tank, Ap, Ad and Hybrid.
But this is the stronges Shaco build in my opinion. Its a creation of myself.

I hope you enjoy the guide & learn something!

Runes

Runes

Precision

Fleet Footwork

Dark Harvest

Phase Rush

Marks: I take 9x Attack-dmg Marks for early jungle clear.

Seals: 9x Seals of heath for early sustain.

Glyphs: 6x CoolDown Reduction for your boxes at the beginning.
3x Attack-dmg for early jungle clear.

Quintessences: 3x Attack-dmg for early jungle clear.

Of course, all of the attack-dmg runes are useful for the late game autoattack burst too. But the main reason I take them is because of the jungle clear. Because this build is autoattack based.

Masteries

Ferocity: 12

Fury : Get the attackspeed for jungle clear & faster burst dmg.

Double Edged Sword : Shaco, needs all the dmg he can get. So these 3% additional dmg are worth to get 1.5% dmg more.

Natural Talent : Its perfect for Shaco because his abilities scale with AP & the 15 free AP on lvl 18 are totally worth it.

Oppressor : Since he got a slow with his "E" he deals additional dmg. Thats why you should open a fight with your "E" first.

Cunning: 18
Wanderer : The faster you are, the better.

Assassin : Its awesome for invading or split pushing. You are often alone & u are not angry about more dmg, thats why you should get a point on this.

Merciless : The enemies die faster, good if you have to dive them.

Dangerous Game : Since you are not on the lane, the other masterie is pretty useless. This gives you some sustain.

Precision: It`s good if they build some armor or magic resist.

Thunderlord's Decree : You will probably always land at least 3 on a enemy, so this is the best keystone for Shaco in my opinion. You can also go with "Stormraider`s Surge" if you prefer that.

Resolve: 0
I did not put any masterie points in here.

1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18

Invisibletext!Invisibletext!Invisibletext! > >
First we get 1 point in "W" for the early Jungle camp clear.
After we got lvl 2, we put 1 point in "Q" for the invade.
From there we max "E".
The reason we max "E" always first, is: we cant miss it! It is a point to click ability what does insane dmg, even as AD Shaco.
If we max & we don't get our enemy to run in our box, its pretty useless beside of jungle clear.
Our "Q" is good for taking it early but maxing is not really the thing we want, because the additional invisible time is not worth to give away our "E" dmg. At lvl 6,11 & 16 we skill our ultimate "R".

Second we max "W".

The rest of the points we invest in our "Q".

Skills

Quoted:

Why so serious?

- ShacoThe spells are the thing that makes Shaco, Shaco.

His passive "Backstab" is so AWESOME i still cant believe it ;D! When ever you attack a enemy form behind, you deal 20% more dmg.

Passive, use ingame

Try to get behind the enemies, that is really easy with ! Also if you go for Dragon, Baron, or Herald. Just ask some one if he can tank the dmg so can you deal 20% more. Remember, this passive also counts for your abilities. Chasing people down with your "E" is so easy.

I think everybody know this ability of Shaco, it`s his trade mark!
Its the "Q" from Shaco. You get invisible for a period time & get a gap closer in a pointed direction. The next auto attack does critical dmg.

Deceive, use ingame

You have to know, the enemies see the smoke of your "Q", also if you are in a bush & they dont`t have warded there.
Use this ability to get use of you passive.
Its perfect for escaping (specially in jungle, because they don`t know int wich direction you jumped) because of this ability you are an extreme slippery champion and almost uncatchable.

Your second ability is your "W", Jack in the box.
It is a box that gets invisible & last for 1 minute (invisible). If some one comes near to it, it fears the individual & attack it. In active condition it lasts for 5 seconds.

Jack in The Box, use ingame

You can use it in so many different ways. After you used Deceive for the gank on a lane, get a distance between you & the enemy laner, so u can place a "W". Then u are visible & you will attack the enemy laner. He will automaticaly run to his turret, where u you have placed your "W". He will be feared & its usually a free kill.(Here I started at 00:45 with placing boxes. I had 4 when the Red came up.

Your next ability is your "E"
Two-Shiv Poison Is a point to click ability, scaling with AP.
It slows enemies when it hits them.

two-shiv poison, use ingame

Two-Shiv Poison is an exccelent ability to get low life people while they are going back. You just jump over the wall with Deceive and kill them with your "E".
Of course it does 20% more dmg if you hit them from behind. Thats why, they should never run away from a Shaco!:D

His last ability is hallucinate!
It is a better version of the passive from LeBlanc
You get a clone, wich you can control & does auto attacks. When it dies or the time expires, he explodes & does magic AOE dmg.

hallucinate, use ingame

It is the perfect ability to confuse your enemies. They see a low life Shaco, he disappears, & suddently THERE ARE TWO OF HIM!! You can get out of every situation if u know how to use him.>1.TIP- Use it when u are invisible with you "Q"
>2.TIP- Move with it ( While pressing R left clicking on the screen)
>3.TIP- If you run away, send it in the other direction, it will be a 50/50 chance that they follow you!
>4.TIP- Keep a eye on the remaining time of your clone, & send him to the enemies if he will explode soon, its free dmg.

Spells

Always take Smite with you. It helps you in jungle clear, & Drake / Rift Herald & Baron Nashor secure.
I prefer to take Ignite with me, over every other summoner spell. It gives you higher chance for first blood & will hurt low life enemies in the late game.

I dont think Shacois a champion who needs Flash because of his Deceive. It already makes him very mobile & it is totally enough if used correctly!

Teleport: Maybe, for efficiently split pushing. But also there, with Deceive & boots you have enough mobility.

about Heal... umm... no!... just no....

Cleanse is actually a pretty good pick because sometimes the enemies have hard CC-champions like Alistar, Riven, Leona or Ashe.

Items

Now we come to the part why i wrote this guide.

The essential item we will buy first is: Skirmisher's Sabre - Devourer.
Stated Devourer is the upgraded item of the normal one. You need to get 30 stacks on it; Gromp, Blue, Wolves, Raptors, Red, Golems 1 stack - Rift Scuttler 2 stacks - Dragon, Rift Herald, Baron Nashor 5 stacks. After you got your 30 stacks it automatically turns into "stated devourer". From then on, it`s passive is active wich triggers every second auto attack on-hit twice. This passive is extremly strong, specially with our following build.
The second item we rush is Guinsoo`s Rageblade.
This item will helps us to clear the jungle very fast. Also, after we have ganked successfully we can help the lane to push more efficiently. It increases out ability power we can need for our boxes, our "E" two-shiv poison and our ulitmate hallucinate.
The additional attack dmg increases the dmg of our auto attacks, & IT GIVES US DMG ON-HIT! Thats exactly what our stated devourer will double every second auto attack!
The last Core item we build is Wit's End.
It gives us more attack speed what shortens the time until we got the 8 Stacks of Guinsoo's Ragebalde, a little bit of magic resist and again DMG ON-HIT!
With this item we have successfully used our passive from TWICE!
Now we got our core items and can check how the game is going.

In my first example build where the 3 additional items are: We have the perfect build. You can easily go for solo baron, if you are unsure, get at least red buff.
All other Items are as I said different to the situation.
The good thing about Shaco is, he can be a really good off tank with the different tanky items you can build on him.

How to?

Now I will explain you, how to gank & how you counter jungle as Shaco!

In my following pictures there are drawn lines. Here is the explenation
-Red line, here you walk normally
-Blue line, here you used your Deceive"Q" to jump
-Yellow dot,there you place a Jack In The Box"W"

In-Depth

COUNTER JUNGLING
First of all I tell you how you start in your jungle. We always start red, & do not need a leash/pull/help. We place our first Jack In The Box at the time 00:45. As soon the cool down is refreshed, we place the next box in the same place. If we continue, we have 4 Jack In The Box at our red camp. After we killed the red & one of the small minions, we place a other Jack In The Box box wich clears the camp up.
Now we walk out of the camp while the box & the last minion are fighting. On the way to the enemies blue, we get lvl 2. We Deceivejump over the wall & walk in to the grass. There we place a other box & steal the blue buff. Now we can fight him because we are full life, mostly first blood.
If he did not start at blue, its a free buff for you!

Ganks, Top, Mid, Bot

The only thing I really want to tell you again is: GET USE OF YOUR PASSIVE!
For top lane the best ganking routs are these:
For Midlane I gank like this:

and our last lane, bot:

Teamfight

We use Deceive to enter the team fight. With the gap closer we get behind the carry. Why we are invisible, we press "R" Hallucinate for more dmg. We also put a Jack In The Box"W" so we can fear some enimies who are near. If you are getting focused, run. If they do not notice you you can attack them from behind & deal as much dmg as you can.
If your team does not need you, or is not fighting at the moment, split push!
get objects & invade the enemy jungle.[/spolier]

My last TIP for you guys is, always have enough mana to use your "Q". Like this you get incredibly slippery & almost uncatchable:D
