normal shaco early game tend not to invade buff if they are a fast jungler because of lack of ignite, so more gank focused pre6, try to have an idea of where you want to gank first by whose in your team, so if you want to gank top, start bot side, (red, blue, gromp wolves, if your ganking mid, skip wolves if ganking top)(blue, gromp, wolves red for bot lane gank and sometimes mid), rush level 6, should hit it from your second blue/red then rush dragon, there are no bad dragons for shaco, prioritize ganking whenever predator is up, has 15 second window so activate it on the way to the gank not just for the gank

mid game is after tiamat boots and static shiv... waveclear just went through the roof son, time to take out bot or top tower (either works although pushing out bot lane alows your bot to roam top whilst you split farm bot), after the towers down you want to grab rift and look for a good opportunity to use it, best to get a good early opportunity cause we want early inhibitors, if your team has a good splitpusher like udyr or trundle/tryndamere etc, run to their lane and push out with them, keeping in mind to save ghost as an escape

ignore team and split to create pressure, if you have pressure split bot, using preadtor, ghost and hopefully yomuus to keep safe, and just sit in the lane until you either get inhib, or drag multiple people to the lane (only do this if you have the early lead so that they dont 5v4 and get baron), then rinse and repeat, making sure above all else not to die, making the enemy chase you for a long time is also a win (only if your team can capitilize), for the most part ignore going for kills, unless they are free, predator can be used whilst invisible, so if you need the speed and are surrounded invis before poping it, also dot affects cancel it so dont use if you have a dot ie red smite or teemo poison on you, try to only group with team if you have both the side inhibs and need mid inhib, or a free baron presents itself, constantly clear out enemy jungle (can "almost" ignore own jungle because you will always be in enemy territory)

predator is good for reaching fights you wouldnt normally make (early game pref save for splitting/escaping late game)
no ignite means worse counter jungling
however ghost means you can chase down people who flash when you gank, meaning that instead of just wasting flash you can also wither kill them or make them back (or just permaslow them so that your laner can catch up)
this build can make you outrun teemo, and alot of faster champions, use this to try and get people to chase you

tiamat and static shiv are not optional, you can grab what boots you like, however pref beserker for attack speed, swiftness are good too, pref not defensive, cause you wont be teamfighting,mobis are good early game for ganking, but selling them late game loses money, and sometimes they prevent you from running away, which is what we want boots for, if you have to, ninja over merc, merc only if neccasary
zzrot is a good pick if you are dueling 1v1 alot at their inhibs, it can get good damage off while enemy is distracted but often does drop fairly quickly, dont be afraid to drop even if it wont last long (pref if you have ult up so they get confused as to who to focus and switch agro between clone and you whilst baiting multiple people)
use ult to dodge, or when the enemy initiates on you, never use it when chasing as it delays you for half a second, making it hard to catch back up (lost lots of kills because i ulted)
build isnt squishy if you build titanic and zzrot, so last item can be whatever you want, could be triforce, could be deadmans, Guardian angel is rediculously good for tilting because it often allows q to come off cooldown. can get banner of command instead of zzrot, but would only do so if you have the gold to buy it imediately after taking baron, i only ever get jungle items if im doing terribly int he early game, and get sent back to base at 650 gold and already have boots
