Not Updated For Current Season
This is a correction to my prior build, i wasnt logged in when i made it.
Ok this is a simple build, relies on critacal strike and damage, mixed in with some Attack speed. Start with a LONG SWORD + MANA POTION to start off the game. Then build into madreds blood razor and eventually into wriggles lantern. When u get wriggles lantern u can place it anywhere to use as a vision ward for 3 minutes.
Shaco is somewhat strong early game but he is very prone to be targeted and does not have much health. So if you choose to fight other champions let your laning partner engage then quick hit and get back. Just harass and minion grind. Dont be too eager to get the kill its better to let a kill go then to die trying or even go 1 for 1. When you get to level six your ultimate is strong and an be used multiple ways.
Shaco now should look somewhat to gank on squishy opponents and other champions with low health. He is strong and will b able to get some kills with a combo and you might have to pop an ignite. With lifesteal and attack damage now stacking up he hits hard... and the posotive is he can almost always Get The **** Out(GTFO). With Decieve.
Shaco should be somewhat fed and hitting extremely hard, squishes will fear shaco and never know where he is lurking. Your quick Combos will most definitely severely injur foes. Try to stay with team fights because you will be able to finish off some kills, but try not to kill steal, your teamates will not enjoy that. The great thing is he can cahse down very well due to decieves jump, and Two shivs slowing effect. So with a combo of those 2 moves and a ghost if necassary its a gauranteed kill.
Most people who play shaco start fights with decieve and then pop behind them, this is a useful way to enter.. My thoughts behind this are because the knee jerk reaction to shacos decive is to start running. The problem is they have full health when theyre running. Instead try saving decieve for when there running. Try tossing your shiv to start then engage for a bit so ur both about 2/3 or 3/4 health they will probably be lower health. Then when they run decieve, two shiv and by then they shld be dead or will be with the slow.
