Shaco is one champion of Life Steal, Attack Damage, Attack Speed and Ability Power.
So i made 3 builds.One is of Life Steal, Attack Damage, Attack Speed and a small Ability Power.
Other is of Ability Power, Life Steal, Attack Damage and a small Armor.
And the third build is of Life Steal, Attack Speed, Attack Damage and a small Ability Power.
Shaco can are jungler, AP and DPS.

Team work is good to feed shaco.In the second build when you finish rabadon's deathcap you kill easy the enemies.
One team work in the game is the most importantly.

JUNGLE=To to Shaco jungle you need learn the second spell for first.
Go wait the golems are summoned.First place a Jack-In-Box in the front of the golems, more care, place they far of the golems to they no attack the golems.After your spell is ready again place more one in the same place.And place more one in the same place(When your spell is ready).
After place the 3 Jacks-In-Box attack the golems and push they to your Jacks.Obs:When your Jacks are dying use smite in one of the golems and kill the other (If the other golem is live).
