Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
when you use shaco his ult comes in handy because when used the clone does half damage that u do so it comes in handy.
first the saphire crystal u will be using a lot of jack in the boxes which makes you lose a lot of mana and it is one of the items u get before sheen.sheen u get because u will do bonus damage after deceive.
2nd boots of swiftness for attack speed.
3rd vampire scepter then malady malady will give u attack speed and life steal and a little bit of over time damage.
4th bf sword then infinty edge because now u got enough attack speed so a little damage would help once shaco get this u guys won !! your decisive and ult will just do so much u wont believe how much it does.
if the game isn't over yet a sword of divine because if u have not noticed yet shaco misses a lot so the sword of divine will keep u attacking.
now a black cleaver for facing tanks and that should make your attack damage 270 and more if u attack more then 3 times it ill be crazy strong plus your clone.
