Shaco is very … adaptive. He has a very high skill level due to the attitude that needs to be adopted in order to succeed with him.
Attitude? - Yes attitude. Shaco is an assassin by default, however he's not just that. He's a major team player and only thrives on helping his team via ganking.

Shaco should be played very, very aggressively in the early game, try to take most of the early-game kills (upto 3) and then try giving SOME (not all) kills away to others.

I say this because as a Shaco, it's quite easy to fall off the wagon early and thus putting you so far behind it's difficult to catch up. You aim in the game is to constantly gank, feeding your team kills / assists, so much infact; that they don't need you, at all.

When your team is at the point where they can 4v5 successfully; That's when your attitude needs to adapt and thus split pushing becomes almost a sure-win tactic.

Now this isn't always 100% true; Split pushing isn't just about being absent minded in regards to your team or the progression of the game; if you notice that your team begins to fall behind in kills / farm. You should re-join your team, pop the squishes and focus on key-objectives such as Turrets > Baron > Drakes.

Keep in mind; Drake and Baron respawns; Turrets don't!

There are times when taking turrets are more beneficial than taking Drake / Baron - Experience will tell you when.

I have provided a full run-down of Shaco in the Build and Skill Allocation notes.

Shaco is not for the faint hearted and does require some experience in order to get to grips with what he can and can't do. Shaco has the ability to 1v3; however this requires a large amount of focus and planning, utilising Shaco's boxes to provide chain CC + Bonus Damage. It is possible to place the boxes in such a way to where 1 box will trigger a long chain of fear's with other boxes resulting in upto ariybd 8 seconds of fear.

Read the guide notes and find your own style.

Good Luck.

With this setup, you have a choice on starting.
If you're on Red Team (Starting on the south of the map), request a pull from your team mates and start [Blue Buff]
[Blue Buff] > Take Q second and run straight into [Baron Pit] > Q over the wall and take the enemies [Red Buff] - Depending on the enemy Jungler, by the time you've finished their [Red Buff]; He'd just about be finishing his [Wolves].

Run into the bush near the enemies [Wraiths] and set up a box to trap. Now at this point you'll have Blue and Red buff + you have ignite.

Just before the enemy Jungler walks into the brush and into your trap (literally just before) > Q behind them and once the enemy has been feared, [Backstab] and proceed to slap away, igniting him and praying to the RNG gods.

Typically this means you get your first kill of the game. By this time your [Smite] will be back up, take his [Wraiths] and then proceed into the river to take [Top Crab].

Check your health and consider ganking [Top] or [Mid].

If you can't get a gank off and your HP is okay, go take your own [Gromp] > [Wolves] > [Wraiths].

If you have enough monies at this point to buy your Tiamat, head back. If not; Look for another gank around [Mid Lane].

If there's no gank available, check to see if you can take [Bot Crab] - Now be careful around here as the enemy Jungler will be around.

> Take [Red Buff] then look for a gank in [Mid Lane] or [Bot Lane] - If there's no ganks available and your HP is okay, you have a choice depending on who the enemy Jungler is playing.

You can try to invade the enemies bottom jungle or take your own [Golum's].

> Recall and buy your next item then proceed to farm your jungle / invade / gank.

Shaco excels at ganking, his entire skill set is based around it. Q behind an enemy, place a box behind him to cut off his escape > [Back Stab] the enemy > E to finish or apply a slow so you can finish.

It's important to note that your E's (Shiv) passive applies a slow to your auto attacks, however it can then be used as an active to throw the Shiv causing large damage and applying a slow. You'd wanna get a few slaps in before using your E, however when your build begins to formulate; use this as a sheet execute.

If you start [Blue Team] (North Spawn) - You can reverse the process, starting on your [Blue Buff] > Q over [Dragon Pit] in attempts to [Smite] the enemies [Red Buff] from under his nose. For this to work; you need to ask your team mates for a good pull, so that you essentially kill [Blue Buff] the second it spawns. If your opponent has taken his [Red Buff] - Try to catch him at his [Wraiths]. By this stage, he would have used his [Smite] on [Red Buff] and would be weak. Go in for the kill and/or try to steal [Wraiths].

> Take [Bot Crab] > [Wolves] > [Wraiths] > [Top Crab] > [Red Buff] > Gank.
