Hi I am The TimeTraveler and I came from the future to say you, haw to make an amazing and unstoppable build as Shaco. Before I start to write descriptions I would like to say a little bit words. Some builds are simply great, but it doesn't work for every player. Each other likes difference strategy, BUT I made build which I think is suitable for everybody. If you will complete it in a game you will be a huge dominate player there. So lets start..read carefully.
P.S. sorry for my English :-p

Shaco was no doubt one of the most overpower champions in League of Legend. The bosses reduced him to normal champion (R.I.P. old buddy) but he is still a Legend if you know how to up great him with items.

Advantages

- Great Assassin
- Insane pusher
- Good tower defender
- On of few, who can take golem down at the beginning of the game
- Great escaper
- Makes confusion at battlefield
- FUNNY GAME WITH HIM

Disadvantages

- Low health champion
- Bad farmer
- In CD is very vulnerable
- Not so strong in team fight (but he will..read more)

So I played Shaco many years thanks to Time Traveling :-D..and I have some good time and bad time with him. But now, I have to say, that I am Shaco specialist and win almost every game with him. How?? I took a think about what he needs. And I simply gave it him with items and it worked.

So what he need?
I think, that most important thing is farming. Because it is at the beginning of the game and it is building stone for late game, because it gives money. So this thing I gave him with Tiamant and believe me or not, but it usually gives me more than 20k in game which takes 45 minutes and I kill about 300-350 creeps. So this about farming.

Second thing, what he really need is Attack Damage..and I mean huge attack damage. There is many items, which gives good damage, but nothing is good like Bloodthirster (my the most favorite item) because other thing what Shaco need is lifesteal. Tell me which item gives you more dmg than this. 60dmg +40 bonus dmg = 100 damage (and with Tiamant you have quickly collected 40 creeps)

Shaco need huge attack damage because of his critical attacks. This is the main ability of this champion. Because deceive gives you certain crit. attack..and now lets go back to school and count :)..with runes on critical damage you will have about 48 bonus critical damage, that means your crit. will give 250% of bonus damage to your enemy. (don't buy infinity edge..it is expensive and final effect is not good for this money) So if you buy two Bloodthirster and one Tiamant you will have about 4k damage..and 250% of 400 damage is...1000 damage..BUT..you will sell Tiamant and buy instead of this another item..and it will depend on situation, but mainly I buy another Bloodthirster because you will not need more money after, because you will not have a space in inventory thanks to two Phantom dancers.

Just routine spell with Shaco..thanks to Cripple also reduce targets armor. This spell is good for attacking quick or tanker champion or simply if you want help your buddy to safely escape.

I almost all the time played with Teleport, but i changed to Ignate and it is really great. Use it to enemies who ran away.

Dont use other spells..if you need some..you are making something badly..think about it..takes buffs for mana and don't use clarity...

For game without special champ I use this build

and after I usually sell Tiamant and buy The BloodThirster

But if you are facing with Malzahar, maybe is not bad to invest money to Quick Silver or if you play against Trynda..buy Thorn Mail..it is really funny after.

I would like to say true informations about his skills because here are old. R.I.P. old buddy :(
- Shaco deals 20% bonus damage when striking a unit from behind. It is important for farming..try to attack from behind.
- Shaco instantly stealths for 3.5 seconds, teleporting to a target nearby location. If he attacks while stealthed, the attack is guaranteed to crit for bonus damage.
Cost: 90 / 80 / 70 / 60 / 50 mana; Bonus Damage: 40 / 60 / 80 / 100 / 120 %; Range: 500; Cooldown: 11 seconds (triggers only when you leave stealth)
- (Active): Shaco creates a Jack in the Box at the target location. It will Stealth after 2 seconds, and pop out when an enemy comes near, fearing nearby enemies for a few seconds and attacking them. It deals magic damage, and lasts 90 seconds stealthed or 5 seconds while firing. Casting Jack In The Box breaks stealth. Cannot be cast inside walls.
Cost: 50 / 55 / 60 / 65 / 70 Mana; Fear: 0.5 / 0.75 / 1 / 1.25 / 1.5 seconds; Magic Damage: 35 / 55 / 75 / 95 / 115 (+0.25 per ability power); Cooldown: 16 seconds; Range: 400; Jack in the Box Attack Speed: 1.359
- (Passive): Shaco's attacks poison his target, reducing their movement speed for 2 seconds. (Active): Deals half weapon damage plus extra damage to target enemy, and poisons them for 3 seconds. The passive is not in effect during the cooldown. Slow Works With Backstab.
Cost: 50 / 55 / 60 / 65 / 70 Mana; Mov. Speed: 20 / 22.5 / 25 / 27.5 / 30%; Magic Damage: 40 / 80 / 120 / 160 / 200 (+1 per ability power)(+0.5 per Attack Damage); Cooldown: 8 seconds; Range: 625
- (Active): Shaco creates an illusion of himself nearby, which deals 25% less damage and receives 50% extra damage. This illusion deals half damage to towers and inhibitors. On death, the illusion explodes, dealing damage to nearby enemies. Lasts up to 18 seconds.
Cooldown: 100 / 90 / 80 seconds; Magic Damage: 300 / 450 / 600 (+1 per ability power); Cost: 100 Mana; Range: 500

Hallucinate clone: now is too simply to know which Shaco is true (clone does not have items, buffs and his life is much quicker down) so it lost main point of this spell to confuse enemies :(. But clone has all of your items (but they are not visible) All of attributes from items what I recommend here has also your clone. Your clone has also crit. damage. Seduce hallucinate is not break deceive!! You can control move of your clone with holding alt!

Combo: first consider carefully if attack from deceive immediately or leave it for finish your enemy. I usually chose the second variant because you never know if your enemy has some hide buddy. So come there, put jack in the box, hallucinate, and hitting, your critical and passive from Two-shiv poison make rest of work. If target start running use Two-shiv poison to slow him and deceive to finish him. (deceive ant late game gives about 1000-1500 dmg)

Fight: try to fight squishy champ like Twich..to attack tank try find some buddy, it is better. Do not risk your life, attack only if you have some advantage for win like 1000 dmg critical :)

Your teammates are often idiots..so do not be angry..just relax and enjoying the game, take always buffs because you are the One who need it..blue buffs gives also cool down! Try to find line where is not tank..if your buddies do not understand it, stay there...much better then be with tank at the beginning.

About kill stealing..Shaco is really great in this..and sorry if you think something other but for kill are money..and kill champ is skill..and you have for it great potential..they will fear you with report or others things but thanks you they will win the game. One more think..if you kill champ with deceive (1000 or more dmg) it is not steal buddies..it is half of life of your enemy.

So thanks for reading..I hope you will have so many fun in game. And remember one thing..it is only game..so take it easy ;) and if you meet some idiot show him, who is better player.

I wish you many wins..lets show them, that....Shaco is still a Legend
